Description
Technical field
The present invention relates to a kind of boiler, more particularly to a kind of reclaiming type coal-burning boiler.
Background technology
The energy waste phenomenon of the coal-burning boiler of prior art, particularly Industrial Boiler is extremely serious.The energy knot of China Based on coal, the industry coal-boiler having a large capacity and a wide range will consume substantial amounts of coal to structure, and the most structure list of existing coal-burning boiler One, tail gas enters from top to bottom purifier by pipeline, and the setting of such pipeline easily causes coal dust deposit buildup in tail gas In the interface of connection purifier, the obstruction of pipeline is easily caused, tail gas circulation is obstructed, and flue blocks and boiler can be transported Row produces great inhibition, causes serious economic loss.
The content of the invention
