附录8 专业外文资料翻译一.英文资料Boiler Circulation&Water TreatmentAn adequate flow of water and water-steam mixture is necessary for steam generation and control of tube metal temperatures in all the circuits of a steam-generating unit. At supercritical pressures, this flow is produced mechanically by means of pumps. At subcritical pressures, circulation is produced either naturally by the action of the force of gravity, by pumps, or by a combination of the two.Fig-1Simple natural-circulation circuit (diagrammatic)including primary steam separator in drumThe force of gravity available to produce flow in natural circulation comes from the difference between the densities (1b/cuft) of the fluids in the downcomer (downflow) and riser (upflow) portions of the circuit (Fig-1). Maximum pumping effect occurs if the fluid in the downcomers is water at or slightly below saturation temperature and free of steam bubbles. Heat-absorbing rises at saturation temperatureconvey to the boiler drum a water-steam mixture of less density than that of the water in the downcomers. This difference in density establishes the force available for circulation.The flow in the various circuits of boiler units designed for forced circulation at subcritical pressures, is produced by mechanical pumps. There are two general types of forced-circulation systems, a “once-through ”system and a “recirculating”system.The “once-through” force-circulation type receives water from the feed supply, pumping it to the inlet of the heat-absorbing circuits. Fluid heating and steam generation take place along the length of the circuit until evaporation is complete. Further progress through the heated circuits results in superheating the vapor. Conventionally this type of force circulation requires no steam-and-water drum. A modification of the “once-through”type evaporates to partial dryness(90%quality) removeing the excess water in a separator.The “recirculation”forced-circulation-type unit has water supplied to the heat-absorbing circuits through a separate circulating pump. The water pumped is considerably in excess of the steam produced and, like a natural-circulation boiler, a steam-and-water drum is required for steam separation. The separated water together with feedwater from the feed pump is returned through downcomer circuits to the circulating pump for another “round trip.”In the recirculating type of forced circulation there is a net thermal loss for the boil unit because of the separate circulating pump. While practically all the energy required to drive the pumps reappears in the water as added enthalpy, this energy originally came from the fuel at a conversion-to-useful-energy factor of less than 1.0. If an electric motor drive is used, the net energy lost, referred to the fuel input in a plant with 33%thermal efficiency, is about twice the energy supplied to the pump motor.Natural circulationIn a natural-circulation system, circulation increases with increased heat input (and increased steam output) until a point of maximum fluid flow is reached. Beyond this point, any further increase in heat absorption results in a flow decrease. The from of the curve, shown in Fig-2, is produced by two opposing forces, An increase in downcomers and risers as the heat absorption increases. At the same time, the friction and other flow losses in both downcomers and risers also increase. When the rate of increase in these losses (caused primarily by the increase in specific volume in the riser circuits) becomes greater than the gain from increasing density difference, is to design all the circuits to operate in the region of the rising part of the curve, to the left of the peak in Fig-2.When design conditions are limited to the rising portion of the circulation curve, a natural-circulation boiler tends to be self-compensating for the numerousvariations in heat-absorption conditions encountered in an operating unit. These include sudden overloads, change in heat-absorbing-surface cleanliness, nonuniform fuel bed or burner conditions,and even the inability to forecast precisely actual conditions over the operating lifetime.Fig-2 typical relationship between circulation in a boiler circuit (at a given pressure) and amount of steam steam produced(scale arbitraiy)No similar compensating effect is inherent in a forced-circulation unit operating at subcritical pressures, since a large part of the total resistance of the riser circuits, much greater than the natural circulation effect, is caused by flow-distribution devices required at the circuit inlets. Under these conditions, because of the disproportionately large resistance of the distributors, an increase in heat absorption to an individual circuit or group of circuits causes only a slight change in the flow rate.The method of producing flow in boiler circuits, whether natural or mechanical, has virtually no bearing on the effectiveness of heat-absorbing surfaces as long as the inside surface is werred at all times by the water in a water-steam mixture of suitable quality to maintain nucleate boiling. Provided this fundamental requirement is met, the water-film resistance to heat flow is negligibly small, and the overall heat conductance depends on gas-side and tube-wall resistances. Within the nucleate boiling regime, boiler heat-absorbing surface in the furnace or convection portion of the unit absorbs absorbs substantially the same amount of heat per sq ft regardless of whether the circulating flow is produced by natural methods or by pumps.With either type of circulation, any departure from the nucleate boiling regime requires special consideration of the forced-convection stearn-film heat transfer coefficient and its relation to permissible metal temperatures.Forced or natural circulationUnder certain conditions forced circulation can be usefully applied to steam generation. Mechanical means to move the fluid within the circuits are employed for boilers designed to operate above or near the critical pressure (3208.2psia.) There are instances, also, in the process and waste-heat fields where temperature control or consolidating heat pickup from widely separated points can be economically effected by the use of pumps. The condition where forced circulation can be applied to advantage are quite specific.Natural circulation is most effectively emploved when large changes in density usually restricted to subcritical pressure designs where thereis a considerable difference in density between steam and water. At pressures above 2900 psi a natural-circulation system becomes increasingly large and costly,and a pump may be more economical to assure positive flow.The forced-circulation principle, however, is equally operable in both the supercritical and subcritical pressure ranges. The selection of the identifying name “Universal-Pressure”boiler reflects the broad applicability of the once-through forced-circulation principle. Its choice,as opposed to the retention of natural circulation in the subcritical range, is essentially determined by the economics of the installation.Fig-3 Densities of steam and water at saturated steam temperaturefor pressures from atmospheric to criticalThe differential in densities of steam and water for the range of 14.7 to 3208.2 psia is noted in Fig-3. A substantial differential persists well up toward the criticalpressure. As long as the maximum effectiveness off this differential is maintained by the efficient separation of the steam from the water in the circnlating system, as with the use of cyclone steam separator, mechanical aid to circulation is not essential.Internal Treatment of WaterThere are numerous chemicals ,some called boiler compounds, on the market and recommended for “internal” water softening and other treatment. Their duty is to stabilize hardness agents, prevent scaling or residual make deposits easily removable. Such chemicals are also used for neutralization of residual hardness in systems after external treatment. Chemicals of this nature are introduced at a more or less constent rate in dissolved state into feed tanks or systems. The most frequently used chemicals with calcium and magnesium salts results in consolable calcium and magnesium phosphates. Other internal treatment agents are calcium hydroxide, sodium carbonate, sodium hyates, tannins and amines.The most effective method of introducing internal treatment compounds to ensure a reasonable degree of quantity control is by means of dosage apparatus consisting of one or more containers having manual or motor driven agitators and a dosage pump.As a general rule internal treatment alone, for waters of much more than 5°(UK)(70p.p.m)hardness is not recommended because system and make-up quantities and water composition may become critical and precipitated sludge and salts are liable to increase density of water and solidification of sludge with consequent propensity to foaming and priming in steam plant and circulation complications.Internal treatment is generally used within limits for smallish systems, say up to 23MW or as residual treatment and to raise pH value to a requisite amount.External Treatment of WaterExternal softening of system and make-up water is the more effective and comprehensive method of water treatment for any size of plant and network and it can suit most water characteristics. Nowadays external treatment involves the principle of ion-exchange, which ensures water of virtually zero hardness.The ion-exchange process can be described as follows. Molecules of dissolved salts are dissociated in from of free electrically charged ions in liquid solution. In the forch field they tend to be attracted to opposite charges: positive cations to the negative cathodes and negative anions to the positive anode. Ion-exchange materials are insoluble artificial resins to which activated chemical groups with tied dissociable ions, are attached. Ion exchangers are classified in accordance with dissociation characteristics of the activating groups, strongly, medium or weakly active.Base exchange water treatmentIn the base exchange process, raw water containing calcium and magnesium salts passes through a bed of cation synthetic resin activated by sodium base. Calcium and magnesium salts are exchanged for quantitatively equivalent salts of sodium (sodiumbicarbonate) and soft water.This neutral ion exchange does not change the salt content of free and tied carbonic acid remain constant. Water softened by the base exchange process is free of calcium and magnesium hardness agents. Sodium bicarbonate is dissolved in water and deposits are prevented. There is a tendency for dissociation of sodium bicarbonate at temperatures above 110℃resulting in some part-tied and tied carbon dioxide being released as aggressive agent.When the active exchange material ceases to be effective due to saturation by calcium and magnesium, its softening power is regenerated by flushing with solution of brine. The high concentration of sodium ions in the brine replaces calcium and magnesium chlorides in the exchange material and reactivates it. Calciumn and magnesium chlorides are flushed out with brine to sewage.There is no practical limit to regeneration and exchane material does not become exhausted. In the case of such mechanical impurities as iron content above 0.3mg/1 or manganese over 0.2mg/1 being introduced by raw water, the exchange material can become contaminated thus experiencing reduced capacity. If such impure waters are involved, introduction of a special pre-filter is good practice ; foreign bodies cannot be dislodged from the exchanger bed in the course of regeneration and frequent renewal of the material would be necessary.The base exchange softener consists of a specially lined steel cylinder, half filled exchange material and provided with suitable connections. The plant can be fully automatic with frequency of regeneration dictated by pre-determined quantity of water passing through or by presence of hardness indicated by test. Adjustment of water quantity is seldom required and chemicals other than salt are not necessary. Paralleling of two interconnected units allows alternate regeneration and therefore contiunity of process.Ion-exchange demineralizationFeed water for modern high pressure plant must be of such quality as to have all salts and dissolved silica acid neutralised. With generation of steam, salts should remain as sediment and condensate virtually becomes distilled water.Much progress in development of methods of water treatment is due to evolution of insoluble artificial resins for the process of ion-exchange in order to render water to a degree of purity required for modern plant. In the demineralization process water is passed through such beds of granulated exchangers in series, to achieve purity of 5~20p.p.m.total dissolved solids.In the cation exchanger, cations in water (calcium,magnesium,sodium and potassium) are exchanged for hydrogen ions, forming free acids from water dissolved salts. In the second series connected anion exchange container,the abovemention ed acid water loses the free acids leaving silica and carbon dioxide. Water is then fully deminerelised.Treatment offering full demineralisation is employed in most power stations and also for manufacturing processes requiring optimum purity of water. Complete demineralization of fill and make-up is not necessary for small and medium sized installations; fully treated water or condensate possibly available from associated or adjacent boiler plant and power stations, proves to be most satisfactory for district heating systems.二.中文翻译锅炉水循环和水处理为了产生蒸汽和控制蒸汽发生设备中所有回路的管壁温度,需要充足的水和汽水混合物。

国产化低压动态煮沸设备在中国啤酒工业中的应用

国产化低压动态煮沸设备在中国啤酒工业中的应用Application of Domestic Low Pressure DynamicBoiling Equipment in China Beer Industry64刘尚义 上世纪九十年代以前中国啤酒糖化煮沸工序均是采用传统工艺。
传统工艺糖化二次蒸汽直接排放,能量不能回收,白白浪费掉。
煮沸时间长,总蒸发强度大,耗能高,不能有效去除可挥发性芳香组分,对蛋白质组分的凝聚有破坏作用,而且排放物污染环境。
“低压煮沸”是1976年由德国霍普曼(Huppmann)公司推出。
低压动态煮沸是从普通低压煮沸发展而来,1996年开始应用到啤酒生产中。
上世纪90年代初,我国开始从国外引进低压煮沸设备,主要厂家包括武汉中德啤酒厂、沈阳雪花啤酒有限公司、青岛啤酒二厂等。
低压煮沸主要以节能为目的,但对啤酒质量兼顾不足。
低压煮沸配备了二次蒸汽回收和热能贮存系统。
煮沸锅内压力在0.01-0.03M的恒定压力下煮沸。
通过提高煮沸过程的锅内压力,从而提高麦汁温度,使煮沸时麦汁对流强烈,缩短煮沸时间,即可以提高煮沸效果又可以节约蒸汽。
麦汁从暂存槽进入煮沸锅前,首先通过板式换热器进行预热。
糖化二次蒸汽将78℃的热水加热到98℃,再用其将72℃麦汁预热到93℃,进到煮沸锅内,98℃热水冷却到78℃。
这样,二次蒸汽回收的热量将麦汁从72℃预热到93℃,节省大量能源。
也有另加一组板式换热器将98℃热水加热到100-102℃,将麦汁从72℃加热到95—97℃。
使外用蒸气只加热5—3℃,便可以使麦汁加热到100—102℃。
回收热能中的40%用于煮沸前的麦汁升温,从72℃升至93℃—97℃,剩余的60%热能制备成85℃热水,供CIP和包装及锅炉用水。
到本世纪初期,我国一直都从国外引进“低压动态煮沸技术”。
2007年长春市万峰轻工设备有限公司首先独立自主的开发出国内第一套低压动态煮沸系统装置,并在华润雪花啤酒(宜昌)有限公司首次应用,一次试车成功。

动态低压煮沸——麦汁煮沸技术的发展现状
麦汁煮沸的目的
●对可挥发性芳香组分的汽提;
●蛋白组分的凝聚;
●酒花及酒花制品的异构化;
●煮沸过程中避免吸氧;
●加热及煮沸的最小耗能;
●沉淀槽中热凝固物的良好分离。
最佳的技术结果只能来源于对煮沸过程的整体把握。
麦汁加热到沸腾温度
过滤麦汁在大约72℃时被转移到煮沸锅中,并被加热。
在加热过程中,麦汁继续以72℃的温度进入煮沸锅。
这样在煮沸锅中形成不均一的麦汁混合物,不同温度的麦汁进到内加热器的底部。
“较冷的”麦汁破坏了加热管中的热平衡,从而打断了向上流。
这个物理过程可以在带有内加热器的煮沸锅中观察到,这就是酿造者常说的内加热器震动。
这种物理现象可以通过改变加热方法来避免,即改善煮沸锅中温度的均一分布;
1.根据一项专利技术,使用循环泵强制麦汁在内加热器中流动,可以产生连续流;
2.麦汁通过板式热交换器进行预加热,可以是:(a)蒸汽加热(由于较高的壁温,有蛋白组分凝聚的风险)。
或者(b)热水加热(避免了不必要的提前凝聚)。
在具有能量贮存系统的啤酒厂里(图1),从贮能罐中出来的97℃的水(循环水),在第二个板式热交换器(Booster HEX)中被蒸汽加热到101℃。
该热循环水逐渐把麦汁加热到期望的煮沸温度。
由于是用水作为热交换介质,麦汁一面的壁温低于麦汁的沸点,有效地减少了不必要的蛋白组分提前凝聚。
由于循环水最终仍然以78℃返回到贮能罐,这项工序并不影响啤酒厂的热水平衡。
从煮沸过程蒸汽中回收的占全部蒸发量的5%的能量完全可以用于麦汁的预加热。
图1 配有能量贮存和“Booster HEX”的麦汁预加热
在酿造过程的开始阶段,用蒸汽加热的Booster热交换器也可以用于贮能罐的加热。
而没有能量贮存系统的啤酒厂则使用来自80℃热水罐的热水,这和上面的过程类似(图2)。
80℃的热水在Booster热交换器中被蒸汽加热到101℃,并在煮沸完成后于80℃左右返回到热水罐中。
所以这种衍生的方法也不会对啤酒厂的热水平衡产生任何影响。
整合了这种麦汁预加热过程的啤酒厂就能避免内加热器的震动。
降低麦汁热应力的同时,有助于对麦汁中的泡沫蛋白组分作温和处理。
由于煮沸锅中温度的连续分布,在煮沸步骤中内加热器的突然启动以及麦汁在搅拌器周围的良好分布都可以实现。
动态低压煮沸
许多几何参数都必须和煮沸锅的设计相配套:内加热器和锥形盖,二级分配器及其在煮沸锅中的位置。
对于可挥发物的汽提,霍夫曼公司在“中国帽子”麦汁分配器的基础上,开发了二级分配装置(图3),这种装置能让麦汁到达麦汁表面两个不同位置,并配有垂直部件,以提高去除麦汁中有害芳香物质的效率。
对于内加热器的锥形盖和麦汁分配器的设计来说,目标是在麦汁煮过程中,锅里形成一种循环运动。
在一个小时的煮沸时间里.锅里的麦汁循环20~30次,完全避免了死角。
设备的设计与工艺的改革相结合,不仅减少了煮沸时间和蒸发率,也对啤酒质量产生了积极的影响。
动态低压煮沸的过程分成以下三个步骤:
● 常压下的预煮沸是为了除去煮沸锅、压力调节系统和蒸汽冷凝器中的空
气; ● 在煮沸锅中增压.然后再释放压力,这个过程重复6次(图4); ● 常压下的后煮沸使麦汁达到需要的浓度。

图3 二级麦汁搅拌器
图4 增压和汽提
在煮沸锅烟道阀附近安装一个旁路控制阀,结合蒸汽冷凝器流通速度的控制,使锅内的压力在规定时间内达到150mbar。
能量通过内加热器将麦汁加热到103℃的沸点。
当达到设定的最高压力时,便开始减压。
煮沸锅内的压力以一定速率降低到50mbar。
压力降低的同时,相应的沸点也降低到101℃,并且整个锅内都产生气泡。
这种称之为“瞬间蒸发”的过程是动态低压煮沸与其他煮沸方法最主要的区别,它对可挥发物的汽提效果很好。
而对于使用内加热器或外加热器的常压煮沸,包括使用双层加热锥体的煮沸方法来说,只有和加热面接触的麦汁达到或超过其沸点。
麦汁中到处都产生气泡。
增大麦汁和蒸汽间的接触面积能够提高对有害风味物质的汽提,同时也有利于热凝固物的凝聚。
上升的汽泡同时也产生一些泡沫。
内加热器在减压步骤中仍然工作,麦汁从搅拌器上喷洒下来,可以避免溢锅现象。
供能升压和瞬间蒸发降压过程大约重复六次。
最后,压力降低到常压状态。
后面一步的作用,是使麦汁达到要求的浓度。
采用这种煮沸方法,可以在45~50min内完成煮沸,保证蒸发率在3.5~5.0%。
对质量诸因素的高要求,使最后一次洗糟在较高的浓度下终止成为可能,其它影响该过程的参数与麦芽价格、浸出物损失以及所需的蒸发率有关。
从初始能量的实际价格考虑,降低浸出物收率及节能的综合效果是非常经济的。
除了经济上的优势,降低蒸发率也有利于环境保护。
麦汁加热如果结合了能量贮存系统,和采用常压煮沸的技术相比,其CO2排放甚至可以减少50%,这和京都会议的指标相吻合。
表1 动态低压煮沸试验的分析结果
表1是在一家德国啤酒厂中进行的试验分析结果,用46min,总的蒸发率能够达到4.4~4.9%。
蛋白组分达到较高的质量标准,最后麦汁中游离的DMS含量低于检测限值。
最终麦汁中总的DMS含量低于75mg/L,对于欧洲啤酒来说,这是非常好的结果。
表2 动态低压煮沸对泡沫的影响
在另外两个啤酒厂,我们检测了动态低压煮沸对啤酒泡沫的影响(表2)。
更新了原有的煮沸方法,蒸发率降低到4.5%。
在这两个啤酒厂中,泡沫NIBEM测定均增加了大约50sec。
这样,A厂就从泡沫中级上升到泡沫高级,C厂则达到了一级泡沫值。
降低蒸发率和能量回收系统的安装对啤酒厂的能耗有显著影响。
表3中可以看出两个啤酒厂的代表性数据,蒸汽消耗用kg/hl冷麦汁表示。
B厂采用浸出糖化法,从52℃开始,加热到75℃需要3.62kg蒸汽/hl冷麦汁。
如果没有能量回收系统,将过滤麦汁从72℃加热到沸点还需要5.98kg蒸汽/hl冷麦汁。
如果安装了能量回收系统.来自蒸汽冷凝器的能量可以将麦汁加热到94℃,这样只需要另外的1.1kg蒸汽/hl冷麦汁就可以将麦汁从94℃加热到沸点。
采用动态低压煮沸的啤酒厂的蒸发率是5.5%。
总的蒸汽消耗是15.8kg/hl,能量贮存系统节省了30%的能耗。
A厂的糖化温度是60℃,加热到76℃需要2.33kg/hl冷麦汁。
这与B厂相比低了35%。
A厂总的蒸发率是3.7%。
但是,回收的能量只能将过滤麦汁加热到90℃,要加热到99℃还需要1.96kg/hl的能量。
总的蒸汽消耗是8.48kg/hl。
动态低压煮沸也可以适当改变。
图5是去掉第一次添加酒花这个步骤的一个例子。
为了避免溢锅,我们在95℃到沸点这个阶段安装了蒸汽的脉冲休止模式,分段加热。
这段时间里蛋白组分适度凝聚,也避免了溢锅现象。
到达99℃的煮沸条件后,动态低压煮沸程序就开始“预煮沸”,酒花在100℃时添加。

麦汁预冷——减少麦汁中游离DMS含量的简单方法
最终产品中的DMS含量取决于原料中DMS前体的含量和煮沸程序的效率与参数的设定。
在煮沸过程中,麦汁中的DMS前体总能转变成DMS。
而游离的DMS则被汽提除去。
麦汁倒到沉淀槽后,对DMS的汽提就终止了,而DMS前体向DMS的转变却仍然在继续。
只有添加像真空蒸发塔或者表面积很大的薄层蒸发器才有可能减少最终产品中的DMS含量。
因为反应速度跟麦汁的温度有关,由此产生一种简单有效的方法:通过一个独立的板式热交换器或者用麦汁冷凝器,将煮沸终麦汁在送入沉淀槽之前,使其温度降到89℃。
DMS含量将被减少近30%,TBA将被减少近20%。

热应力和DMS的进展
图6和图7不同煮沸技术对游离DMS和热应力组分(用TBA表示)的影响。
这些数据来自四个具有不同煮沸设备的啤酒厂。
内加热器、机械蒸汽再压缩和动态低压煮沸系统可以得到相似的结果:DMS 含量在倒锅时减少,在沉淀槽静置时增加。
而锥体加热系统,则需在沉淀槽静置后增加一个汽提步骤,使冷麦汁的DMS含量降到33mg/L。
图6不同煮沸技术的游离DMS比较
图7不同煮沸技术的热应力(TBA)比较
图7的最后一组数据表示的是这些煮沸方法的热应力增加(ΔTBA)情况。
蒸汽压缩煮沸系统由于供给加热器的压力、温度都比较低,所以其ΔTBA只有16个单位。
接下来的是只有预加热程序的动态低压煮沸系统,使用内加热器加热并煮沸麦汁,ΔTBA达到最大,在这个例子中,满锅麦汁与冷却麦汁的ΔTBA达到33个单位。
总结
动态低压煮沸对麦汁质量和能耗的影响有以下几个内容:温度、沸腾次数、预煮和常压后煮沸。
除了高度的灵活性,这种有效的方法有可能与降低能耗、提高啤酒质量的相关措施广泛联系。
这里提到的每个系统都可以单独安装,甚至各个啤酒厂也可以通过对现有装备的改造来实现。
