炉子点火及火焰监测系统作业指导书

炉子点火及火焰监测系统作业指导书一、编制目的:为了提高自控仪表维护人员的技术水平,在生产维护中能及时处理仪表故障,特编制此指导书。
二、适用范围:本作业指导书适用于自动化仪表专业班组维护人员在处理石油化工装置加热炉、转化炉及焚烧炉的自动点火及火焰监测系统故障三、结构及原理:自动点火系统由点火枪、高压包、程控器和火焰监测器等组成。
点火系统是由程控器控制点火变压器产生的几千伏甚至上万伏的高压在点火枪的阳、阴极间产生的连续间隔的电火花,将可燃气点燃。
同时由火焰监测器监测火焰的有无,如果检测点火正常,则停止点火,如果在规定时间内没点着火,则自动停止点火。
火焰监测器由探头和监测仪表组成,它主要分成电离式和紫外线式两种。
电离式火焰监测器是火焰产生电离使之产生微电流,而判断是否有火焰。
紫外线式是监测火焰中紫外线的有无,从而判断是否有火焰。
自动点火系统结构如下图:图1-6.1四、危害分析及安全措施:由于点火枪在点火时有高电压产生,因此在检查点火枪和点火变压器时要注意防止电击,带电时不能直接接触,避免高压电击伤人。
一般情况下应关闭电源检查。
由于炉堂中有可燃气,有的炉子还有有毒有害气体,点火前炉膛必须按程序进行吹扫,确认吹扫干净后才具备点火条件吹扫完成后才能点火,绝对禁止未吹扫,先进燃烧气再点火,这样炉子有发生爆炸的可能。
同时在检查炉膛里面点火枪和火焰监测器等控制元件时应该先关闭燃气控制阀门和介质入口阀门,并且检查时应配戴防护眼镜和防护面罩。
在检查程控器线路时,由于线路一般都带220VAC高压电,为了防止电击,必须使用绝缘工具和仪器,并且要防止短路。
由于炉膛内部温度高,检查火焰监测器时不能随便关闭其冷却风,防止损坏火焰监测器。
五、点火系统常见故障及排除方法1、自动点火系统不点火故障分析步骤:程控器点火控制程序是否正常,如不正常检查软件及硬件,逐一排除,更改或更换。
达不到点火条件,程控器不能启动,必须满足点火条件2、点火时有火花点不着火:点火枪位置是否插对,如不对调整到合适位置,确保点电火花能量点火枪阳极是否洁净,如有污垢,清理干净检查燃烧气电磁阀是否打开。

Do not swap the burner caps around.Switching on manually1.Press the chosen burner control knob and turn itanticlockwise to the required setting.e any type of lighter or flame (cigarette lighter, matches,etc.) and bring it close to the burner.Switching on automaticallyIf your hob can be switched on automatically (ignition sparkers):1.Press the chosen burner control knob and turn itanticlockwise to the maximum power setting.While the control knob is still pressed down, sparks are produced on all burners. The flame ignites.2.Release the control knob.3.Turn the control knob to the required setting.If it does not come on, turn the control knob to the off setting and repeat the steps above. This time, press and hold the control knob for longer (up to 10 seconds).: Risk of deflagration!If after 15 seconds the flame does not ignite, switch off the burner and open a nearby window or door. Wait at least one minute before trying to switch the burner back on.Safety systemDepending on the model, your hob may have a safety system (thermocouple) that prevents the flow of gas if the burners accidentally switch off.To ensure that this device is active:1.Switch on the burner as usual.2.Without releasing the control knob, press and hold it downfirmly for 4 seconds after lighting the flame.Additional wok pan support Only for use on wok burners with pans with a round base.The additional wok pan sup-port should be used to pro-long the appliance's usefullife.5Switching off a burnerTurn the corresponding control knob clockwise to the 0 setting.Power levelsThe progressive control knobs can be used to control the power needed, from minimum to maximum power.WarningsIt is normal to hear a soft whistling noise while the burner is operating.When first used, it is normal for the burner to give off odours. This does not pose any risk and does not indicate a malfunction. They will disappear in time.An orange-coloured flame is normal. This is caused by the presence of dust in the atmosphere, spilt liquids, etc.If the burner flames are accidentally blown out, switch off the burner operating control knob and do not try to relight it for at least 1 minute.A few seconds after the burner is switched off, a sound (thud) will be produced. This is not a fault - this means that the safety device is no longer operating.Keep the burner as clean as possible. If the ignition sparkers are dirty they will not light properly. Clean them periodically using a small non-wire brush. Bear in mind that the ignition sparkers must not suffer any serious impacts.Cooking guidelinesSuitable pansPrecautions for useThe following advice is intended to help you save energy and prevent pan damage:Setting ÛControl knob offHigh flame —Maximum capacity or aperture and elec-tricity onLow flame˜Minimum capacity or apertureBurner Very high - HighMediumLowWok burnerBoiling, steam-ing, griddling,toasting, paellas, Asian food (wok).Reheating and keeping things hot: cooked and pre-cooked dishes Rapid burner Escalopes,steaks, ome-lettes, frying Rice, white sauce, ragout Steaming: fish, vegeta-blesSemi-rapid burnerSteamed pota-toes, fresh vege-tables, vegetable stews, pasta Reheating, keeping things hot and making tasty casse-rolesAuxiliary burnerCooking: casse-roles, rice pud-ding, caramelDefrostingand slowcooking: veg-etables, fruit and frozen productsMelting: but-ter, choco-late, jelly Burner Minimum pan diameter Maximum pan diameter Wok burner 22cm 30cm Rapid burner 22cm 26cm Semi-rapid burner 14cm 20cm Auxiliary burner12cm16cmUse pans which are the right size for each burner.Do not use small pans on large burners. The flame must not touch the sides of the pan.Do not use damaged pans, which do not sit evenly on the hob. Pans may tip over.Only use pans with a thick, flat base.Do not cook without using a lid and make sure the lid is properly fitted. This wastesenergy.Always centre the pan over the burner, not to one side. Otherwise it could tip over.Do not place large pans on the burners near the control knobs. These may bedamaged by the very high temperatures.Place the pans on the pan supports, never directly on the burner.Make sure that the pansupports and burner caps are correctly positioned before using the appliance.Pans should be placed on the hob carefully.Do not strike the hob and do not place excessive weight on it.Never use two burners or heat sources to heat one single pan.Do not use grill pans,earthenware casserole dishes, etc. for a long period of timeon maximum power.6CleaningOnce the appliance is cool, use a sponge to clean it with soap and water.After each use, clean the surface of the respective burner parts once they have cooled down. If any residue is left (baked-on food, drops of grease etc.), however little, it will become stuck to the surface and more difficult to remove later. The holes and grooves must be clean for the flame to ignite properly. The movement of some pans may leave metal residue on the pan supports.Clean the burners and pan supports using soapy water and scrub with a non-wire brush.If the pan supports are fitted with rubber rests, ensure thatthese are also cleaned. The rests may come loose and the pan support may scratch the hob.Always dry the burners and pan supports completely. Water droplets or damp patches on the hob at the start of cooking may damage the enamel.After cleaning and drying the burners, make sure the burner caps are correctly positioned on the diffuser.Caution!■Do not use steam cleaners. This could damage the hob.■Never use abrasive products, steel scourers, sharpimplements, knives, etc. to remove bits of hardened food from the hob.■Do not use knives, scrapers or similar implements to clean the point where the glass meets the burner trims, the metal frames or the glass/aluminium panels, if fitted.MaintenanceAlways clean off any liquid as soon as it is spilt. This willprevent food remains from sticking to the hob surface and you will save yourself any unnecessary effort.Never slide pans across the glass surface, as you may scratch it. In addition, try not to drop heavy or sharp objects on the glass. Never strike any part of the hob.Grains of sand that may come from cleaning fruits and vegetables will scratch the glass surface.Melted sugar, or foods which contain a lot of sugar which may have spilt, should be cleaned off the hotplate immediately,using the glass scraper.Sometimes certain faults detected can be easily resolved. Before calling the Technical Assistance Service, bear in mind the following advice:FaultPossible causeSolutionThe general electrical sys-tem is malfunctioning.Defective fuse.Check the fuse in the main fuse box and change it if it is damaged.The automatic safety switch or circuit breaker has tripped.Check the main control panel to see if the auto-matic safety switch or circuit breaker has tripped.The automatic switching on function does not work.There may be food or cleaning products stuckbetween the ignition sparkers and the burners.The space between the ignition sparker and the burner must be clean.The burners are wet.Dry the burner caps carefully.The burner caps are not correctly positioned.Check that the burner caps are correctly posi-tioned.The appliance is not earthed, is poorly connected or the earthing is faulty.Contact the installation technician.The burner flame is not uni-form.The burner components are not correctly posi-tioned.Correctly place the parts on the appropriateburner.The grooves on the burner are dirty.Clean the grooves on the burner.The gas flow is not normal or there is no gas.The gas supply is blocked by gas taps.Open all gas taps.If the gas is supplied from a gas cylinder, check that it is not empty.Change the gas cylinder.The kitchen smells of gas. A gas tap has been left on.Turn off the taps.Incorrect coupling of gas cylinder.Check that the coupling is sound.Possible gas leak.Shut off the gas supply, ventilate the premises and immediately notify an authorised installation techni-cian to check and certify the installation. Do not use the appliance until ensuring that there is no gas leak in the installation or appliance itself.The burner immediatelyswitches off after releasing the control knob.The control knob was not held down for long enough.Once the burner is on, hold the control knob down a few seconds longer.The grooves on the burner are dirty.Clean the grooves on the burner.7When contacting our Technical Assistance Service, please provide the product number (E-Nr.) and production number (FD) of the appliance. This information is given on thespecifications plate located on the lower section of the hob and on the label in the user manual.Warranty conditionsIn the unlikely event that the appliance is damaged or does not meet your expectations in terms of quality, please inform us assoon as possible.

附件 第一篇 技术说明 前言 “DZHJ型锅炉炉膛火焰电视监视系统”是深圳东方锅炉控制有限公司在吸取国内外先进技术的基础上,自行开发研制出的一种内窥式锅炉炉膛火焰电视监视系统。该系统将摄像镜管部件部分地插入锅炉炉膛,从炉壁上部总体监视炉膛内燃烧状态,其视场内可看到整个炉膛的火焰情况。运行人员在集控室通过彩色电视监视器能观察到炉膛火焰的真实图像。在锅炉点火、低负荷运行或发生危害锅炉正常运行的故障时,该系统有助于防止锅炉炉膛灭火放炮,是锅炉安全、经济、可靠运行不可缺少的设备。适用于电站各类型锅炉:四角喷燃、对冲、W火焰及流化床锅炉。
系统概述 DZHJ气冷内窥式高温工业电视系统采用微气量保护方式,通过电动执行器将摄像镜管伸入到高温炉膛内获取炉内图像,并将图像信号传输至监视器的特种工业电视系统。系统采用结构化设计,安装维修便捷,环境适应性强,抗干扰能力强,耐高温耐腐蚀,视场角大,图像清晰,用气量少,使用寿命长。
性能特点 采用专门研制的特种耐高温针孔镜头,视场角大(90º),分辨率高(32线对/mm),镜片采用耐高温材料制造,最前端为蓝宝石镜片,极大提高了镜头的耐高温性能、抗污染能力和使用寿命; 摄像镜管无需水冷却,也不需微型制冷器,只要少量压缩空气或氮气吹扫镜头。高温镜头具备自清洁功能,克服了传统水冷却摄像镜管易堵塞、腐蚀、漏水及管路复杂、易损坏、使用寿命短等缺点。同时,由于无需铺设冷却水管道,安装维护简单、工程费用少; 摄像镜管防护罩采用特种耐高温耐腐蚀材料及特殊的结构设计,有效保护高温光学镜头及摄像机,摄像镜管结构设计合理简单,维护方便,使用寿命长。采用重力式自锁炉门,结构简单动作可靠,不会因炉门受热变形产生机械故障,在冷却保护夹套退出炉膛后能自动关闭窥视孔以密闭炉膛; 图像采集单元采用先进的低照度、高动态范围、高清晰度彩色CCD摄像机,配合我公司开发的可以遥控调节光圈的高温镜头,保证清晰观察炉膛内部图像; 电动执行器采用永磁低速同步电机驱动及先进的链条式传动,动作灵活自如, 可电动/手动两用,克服了传统的丝杠螺母结构容易变形卡死的情况,整个系统结构简单、紧凑、精致,重量轻; 现场及控制室均可以对摄像镜管进退及镜头光圈大小进行控制。当压缩空气压力低于设定值或摄像镜管内部温度高于设定值时,摄像镜管能够自动退出炉膛,观察孔自动关闭并送出报警信号。
