Circulating fluidized bed boiler slag cooler cooling water series air heater system

The utility model discloses a circulating fluidized bed boiler slag cooler cooling water series air heater system which comprises a shaft seal heater, the output end of the shaft seal heater is divided into two paths, the first path is communicated with a No.7 low-pressure heater and provided with a water supply operation table adjusting door, the second path sequentially passes through a slag cooler cooling water adjusting door, and the third path is communicated with a No.7 low-pressure heater and provided with a water supply operation table adjusting door. And the slag cooler, the boosting device and the air heater are communicated with a No.7 low-pressure heater. According to the utility model, the temperature of the ash discharged by the slag cooler can be reduced, so that the slag discharge heat in the ash is deeply recovered, and the influence on a regenerative system of a turboset is small. 本实用新型公开了一种循环流化床锅炉冷渣器冷却水串联暖风器系统，包括轴封加热器，所述轴封加热器的输出端分为两路，第一路与7号低压加热器相连通，第一路上设置有给水操作台调节门，第二路上依次通过冷渣器冷却水调节门，冷渣器、升压装置
