One end is equipped with gas exit, the intracorporal heat exchanger tube of cylinder positioned at gas inlet and gas exit between, heat exchanger tube and gas inlet and
It is respectively equipped with baffle between gas exit, heat exchanger tube is corresponded in the cylinder equipped with soot blower.
Further, the heat exchanger tube, which is located between one end and cylinder inboard wall of gas inlet, is equipped with baffle, makes to pass through coal gas
The coal gas that import enters outside heat exchanger tube to gas exit through flowing.
Further, the heat exchanger tube, which is located between one end and cylinder inboard wall of gas exit, is equipped with baffle, makes through heat exchanger tube
The coal gas of flowing prevents coal gas short-circuit when circulating by gas exit.
Further, the steam inlet duct and steam outleting pipe extend respectively to outside cylinder.
Further, the soot blower is connected to nitrogen inlet duct, and nitrogen inlet duct extends to outside cylinder.
Further, the cylinder body bottom is equipped with ash bucket, and ash bucket is connected to cylinder, and the exterior contour of ash bucket is truncated cone-shaped.
Further, the heat exchanger tube is snakelike heat exchange tube, and heat exchanger tube is using light pipe, ratio-frequency welding winding fin or both combination
