锅炉采用床下油点火方式；流化床布风板采用水冷布风板结构，布置钟罩式风帽，锅炉采用3台给煤机由炉前给煤；分离装置采用高温汽冷旋风分离器。

1×75t/h CFB for power plant, whose type is YG-75/5.29-M circulating fluidized bed boiler, is produced by Jinan boiler group Co., Ltd. The boiler is circulating fluidized bed boiler of 75t/hintermediate pressure, intermediate temperature, which has the characteristics of high combustion efficiency, low pollution and fuel saving and easy to be regulated, etc. The boiler structure is simple and compact, and the profile is similar with the traditional pulverized coal fired boiler. The boiler is composed of combustion equipment, coal supply unit, ignition unit under bed, separation &return unit, water cooling system, superheater, economizer, air preheater, steel frame, terrace stairs, oven wall, etc. The boiler adopts the ignition method by oil under bed; the grid plate for fluidized bed adopts water-cooled grid plate structure, bell-shaped hood, and boiler adopts 3 feeders to supply coal from the front of boiler; separating device adopts high temperature steam cold cyclone separator.额定蒸发量：75t/hRated evaporating capacity: 75t/h过热蒸汽压力：5.29MPaSuperheated steam pressure: 5.29MPa过热蒸汽温度：485℃Superheated steam temperature: 485℃给水温度：150℃Water supply temperature: 150℃排烟温度：145℃Exhaust smoke temperature: 145℃一次风预热温度：140℃Primary air preheating temperature: 140℃二次风预热温度：140℃Secondary air preheating temperature: 140℃石灰石颗粒度要求：≤2mmLimestone grain: ≤2mm脱硫效率：80%Desulfuration efficiency: 80%钙硫比2-2.5Ratio of calcium to sulfur 2-2.5燃料的颗粒度要求：≤10mmFuel grain: ≤10mm锅炉热效率：87％Boiler heat efficiency: 87％锅炉燃料所需空气分别由一、二次风机提供。

一次风机送出来的冷风经过一次风空气预热器预热后，分别进入炉后的三个点火风道再引入水冷风室中，通过安装在水冷布风板上的风帽，进入燃烧室；由左右两侧风道还分别引出一根播煤风管道，两根播煤风管在炉前汇合形成播煤风母管。

二次风经过二次风空预器后由前后墙进入炉膛；为保证二次风充分到达炉膛，本炉采用炉下部锥体段前后墙进风结构；二次风喷嘴分三层布置，以利燃烧的调整和控制氮氧化合物的排放。

燃煤在炉膛内燃烧产生大量烟气和飞灰，烟气携带大量未燃尽的碳粒子在炉膛上部进一步燃烧放热后，经过高温过热器，进入两个旋风分离器中，烟气和物料分离，被分离出来的物料经过返料器再返回炉膛，实现循环燃烧。

经分离后的“洁净”烟气经转向依次通过高温过热器、减温器，低温过热器、省煤器、二次风空气预热器、一次风空气预热器由尾部烟道排出。

燃煤经燃烧后产生的炉渣，较大颗粒可经炉底三个φ108的排渣管排走再经滚筒冷渣器冷却后排出，较小颗粒的炉灰可以从旋风分离器下部的返料器的细灰管排出。

The air required by boiler fuel is respectively supplied by primary air fan and secondary air fan. The cold air which supplied by primary air fan respectively enter into the 3 ignition air flues behind boiler after being preheated by primary air preheater, then into water cooled wind room, and through the funnel cap which installed on water cooled grid plate to enter combustion chamber; From left and right air flue, one coal distribution air duct goes out, and two of which join together before boiler to become the main coal distribution air duct. Secondary air passes secondary air preheater to enters the furnace from the front & rear wall. So as to guarantee secondary air fully reaches furnace, this boiler adopts air inlet structure of furnace bottom cone section front & rear wall; Secondary air nozzle is arranged in three layers in order to conveniently adjust combustion and control the emission of oxynitride. Fire coal is burning in furnace, which produces much flue gas and fly ash, the smoke with a large number of unburned carbon particles, then after further burning in furnace, they pass high temperature superheater to enter the two cyclone separator, thus the flue gas separates from materials which return to furnace by material returner to realize recycled combustion. The separated “clean” flue gas is been discharged from the rear flue when they successively pass through high temperature superheater, desuperheater, low temperature superheater, economizer, secondary air preheater, primary air preheater. Big grain of cinders which generated from burned coal can be discharged by the 3φ108 slag discharge pipes at bottom of furnace, and the small ones be discharged by the thin ash pipe for material returner which is located below the cyclone separator.锅筒内径为Φ1500mm，壁厚为600mm，筒体全长10204mm,两端采用球形封头，正常水位在锅筒中心线以下100mm处。
