Revolving furnace disc

Abstract

The invention relates to a revolving furnace disc. The small revolving furnace disc solves the technical problem that an existing vertical type coal and biomass firing furnace can only depend on hand burning. Through the invention of the involute automatic deslagging revolving furnace disc, machine burning of the vertical furnace is achieved, manpower is saved, the heat efficiency of the furnace is improved, and energy conservation and environment protection ate achieved. According to the revolving furnace disc, a combustion zone formed by a scraper blade in an involute manner and a side wall is adopted, when continuously fed into the revolving furnace disc through a packing auger, fuel starts burning at the feeding position, gradually-burnt fuel (ash) rotates along with rotation of the furnace disc, and the ash will be discharged out of the furnace disc along the involute direction of the scraper blade when the ash rotating along with the furnace disc is in contact with the involute scraper blade. Due to the fact that accumulated ash has influences on the burning effect, continuous burning of the fuel on the revolving furnace disc is achieved, and the fuel is more sufficiently burnt on the revolving furnace disc. By means of the above reasons, the revolving furnace disc can be widely applied to the field of the vertical furnace.

Description

technical field [0001] The invention belongs to the field of vertical boilers, in particular to a rotary furnace pan. Background technique [0002] At present, most of the boilers used for coal and biomass combustion are large reciprocating and chain grates, which are all reciprocating, so they are not suitable for vertical boilers. Most of the small vertical boilers are fixed grate manual firemen, the ash and slag are easy to coke, the ventilation is not smooth, the combustion is not exhausted, the heat efficiency is low, and the combustion conditions are unstable. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention aims to provide a rotary stove. This small rotary stove solves the technical problem that existing vertical coal-fired and biomass-fired boilers can only be fired by hand. Through the invention of the involute automatic slag-discharging rotary furnace, the vertical boiler can be fired automatically, sa...
