Description
Technical field
The present invention relates to a kind of boilers, more particularly to a kind of reclaiming type coal-burning boiler.
Background technology
The energy waste phenomenon of the coal-burning boiler of the prior art, especially Industrial Boiler is extremely serious.The energy knot in China Structure is based on coal, and the industry coal-boiler that has a large capacity and a wide range will consume a large amount of coal, and the most structure list of existing coal-burning boiler One, tail gas enters purifier from top to bottom by pipeline, and the setting of such pipeline be easy to cause coal dust deposit buildup in tail gas In the interface of connection purifier, it is be easy to cause the obstruction of pipeline, tail gas circulation is obstructed, and flue is blocked and can be transported to boiler Row generates great inhibition, causes serious economic loss.
Invention content
