Problems solved by technology

[0002] Most of the small and medium waste incineration plants are built in the urban-rural fringes of small and medium-sized cities and towns. Due to the constraints of planning and regional economic development and the smoke generated by waste incineration contains a large amount of corrosive gas and a large amount of fine dust, the heat generated by small and medium waste incineration has not yet It has been actively and effectively developed and utilized, and a large amount of incineration is discharged into the atmosphere with flue gas, resulting in a great waste of heat resources

Abstract

The invention discloses a waste heat boiler for a small waste incineration plant. The waste heat boiler comprises a waste heat boiler body, a steam pocket and a lower header. One end of the waste heat boiler body is connected with an incinerator through an expansion joint, and the other end thereof is connected with a dust remover through an expansion joint. One end, close to the incinerator, of the lower header is connected with the steam pocket through an anti-coking pipe. One end, close to the dust remover, of the lower header is connected with the steam pocket through a convection heat absorption tube bundle. The convection heat absorption tube bundle comprises a light tube bundle and a fin tube bundle which are sequentially arranged along a smoke coming direction. A safety valve is connected to the upper surface of the steam pocket. A blow-down valve is disposed on the lower surface of the lower header. Dust cleaning openings are symmetrically formed on the sides of the lower header. The waste heat boiler is capable of fully utilizing waste heat.
