Description
Technical field
The utility model is related to coal-burning boiler fields, are more particularly, to what a kind of improvement high basic metal coal stain coking
System.
Background technology
The higher coal of alkali metal content alkali metal elements such as contained sodium potassium in burning are changed into gaseous state at high temperature, when
When encountering the lower heat convection face of temperature, it can be deposited on heat convection surface in solid form.Because it is with higher stickiness
Heat-transfer surface can be caused to stain after absorption flying dust, and be not easy to be removed by soot blower, heat-transfer surface heat exchanged thermoresistance will be caused to increase, pot
Stove, which is contributed, to be reduced.
The existing technology to solve the contamination problems of high basic metal coal is broadly divided into three classes, and the first kind is before combustion to combustion
Material is pre-processed, and is recycled after carrying out dealkalize metal to raw coal：Such as Chinese patent CN202671513U uses slurrying system
