1减温器作用及结构减温器的作用是调节蒸汽温度,一般分为表面式减温器和喷水减温器,电站锅炉一般采用喷水减温器。超临界锅炉(主蒸汽压力P≥22.1MPa)过热器的蒸汽温度由燃料/给水比和两级减温水来控制。一级减温器一般位于低温过热器出口集箱与屏式过热器进口集箱的连接管道上;二级减温器一般位于屏过出口集箱与高温过热器进口集箱的连接管道上。每一级
1 desuperheater role and structure The role of desuperheater is to regulate the steam temperature, generally divided into surface desuperheater and water desuperheater, power plant boilers generally use water desuperheater. Supercritical boiler (main steam pressure P ≥ 22.1MPa) superheater steam temperature by the fuel / water ratio and two levels of water to control. A desuperheater is generally located in the low temperature superheater outlet header and the screen superheater inlet header connection pipe; two desuperheaters are generally located in the screen over the outlet header and high temperature superheater inlet header connection pipeline. Every level
