Boiler with annular upper furnace body deashing chamber

Abstract

The invention relates to a boiler with an annular upper furnace body deashing chamber, comprising a furnace body, a furnace cavity and a water outlet, wherein a water tank positioned at the upper end of the furnace body is internally provided with the annular upper furnace body deashing chamber; the upper end of each uplink flue is communicated with the annular upper furnace body deashing chamber, and the upper end of each downlink flue is communicated with the annular upper furnace body deashing chamber; the furnace body positioned on the side edge of the annular upper furnace body deashing chamber is provided with at least one deashing door; and the 2-3 deashing doors are distributed at intervals. The invention can conveniently and effectively clean the smoke dust positioned on the uplink flues and the downlink flues and has the advantages of simple structure, low cleaning cost, good safety and greatly prolonged service life of the boiler.

Description

technical field [0001] The invention belongs to a boiler with a dust-cleaning chamber on an annular upper furnace body. Background technique [0002] The traditional reciprocating flue boiler structure uses the upper and lower flues to pass through the water tank at the upper end of the boiler to increase the heat absorption area in the water tank and improve thermal efficiency. But the shortcoming of this reciprocating flue boiler structure with the upper and lower flues is that the smoke and dust from coal combustion in the furnace will be deposited at the intersection of the upper and lower flues due to the slowing down of the flow velocity, and the smoke will be destroyed for a long time. To block the intersection of the upper and lower flues, it is necessary to cut and dissect the boiler to expose the upper and lower flues to clean the smoke and dust. Repairing in this way will not only cost too much to dismantle the boiler, but also take too long, and the user cannot a...
