300MW循环流化床锅炉压火及热态启动方案

300 MW CFB Boiler Pressure Fire and Hot Start-up Scheme

分析了300 MW循环流化床锅炉压火的目的及意义,压火及热态启动操作步骤及注意事项。压火时应严格控制床温、汽温、缸温、汽压下降速率;热态启动时应调整好风量,控制好投煤时机及投煤量;压火期间及热态恢复过程中应控制好环保指标。

The purpose and significance of 300 MW circulating fluidized bed boiler fire pressure,the operation steps and precautions of fire pressure and hot state start-up are analyzed.The bed temperature,steam temperature,cylinder temperature and steam pressure drop rate should be strictly controlled.
