Solid fuel combustion apparatus

Abstract

Disclosed is a combustion device (100) for solid fuels. An air inlet side (101) is formed above a furnace grate (14) in a furnace (10) and on one side of a fuel stocking layer (1) of the combustion device (100), a combustion side (102) is formed in the furnace (10) on the other side opposite to the fuel stocking layer (1); a shuffle mechanism (6) is arranged in the fuel stocking layer (1) above the furnace grate (14) for receiving the solid fuels, and the fuels in a combustion state can be shuffled by controlling the movement of the shuffle mechanism (6), which is beneficial for discharging ash.

Description

technical field [0001] The invention relates to the field of solid fuel combustion, in particular to a solid fuel combustion device. Background technique [0002] From the perspective of fuel classification, solid fuel is the most widely used combustion material for modern humans because of its rich resources and safe use, especially coal. In addition, with the increase of demand for mineral solid fuel represented by coal, the reduction of resources, and the development of the global new energy movement, renewable biomass combustion materials, such as straw, straw, wood, sawdust, Dead branches etc. are highly valued by people. [0003] At present, the main method of using biomass combustion materials is to directly ignite and burn, which has a very low combustion efficiency and produces a large amount of black smoke, causing environmental pollution. [0004] For a long time, many people have tried to use existing coal-fired stoves to burn biomass fuel. Since the combustio...

Problems solved by technology

[0019] The working principle of the combustion device of the solid fuel of the present invention is described as follows. During the combustion process, the volatile matter and the fixed carbon combustion of the fuel are all in the stockpile layer. Under the action of gravity, it automatically moves downwards and is gradually ignited by the combustion flame in the lower layer. New fuel is automatically added to the stockpiling layer from the feed port, and the fixed carbon combustion of the fuel in the lower layer provides the required heat for the volatile separation of the new fuel in the upper layer. , the replenishment rate of the new fuel depends on the combustion rate of the lower fuel, thus naturally realizing the matching of the volatile matter precipitation in the upper layer and the burning rate of the fixed carbon fuel, effectively solving the safety hazards existing in the existing hot blast stove due to the mismatch of the burning rate
