Blockage-proof horizontal type combustion chamber

Abstract

The invention provides a blockage-proof horizontal type combustion chamber. By adoption of the blockage-proof horizontal type combustion chamber, fuel can be combusted sufficiently and is prevented from being coked and accumulated, and cyclone pipes can be prevented from being blocked. The blockage-proof horizontal type combustion chamber comprises a horizontal type hearth, the rear end of the hearth is closed, and an outlet of a fuel feeding channel is formed in the closed end of the hearth. An auger is arranged in the fuel feeding channel, a plurality of cyclone pipes are arranged on the inner wall of the hearth, and the rear ends of the cyclone pipes penetrate through the closed end to communicate with an air inlet channel; and air outlets are formed in the cyclone pipes, an acute angle is formed between the axis direction of each air outlet and the radial direction of the hearth, so that vortexes which rotate in the same direction are formed in the hearth by gas entering the cyclone pipes from the air inlet channel and coming out from the air outlets. The blockage-proof horizontal type combustion chamber is characterized in that through holes are formed in the front ends of several cyclone pipes close to the bottom of the hearth.

Description

technical field [0001] This technology relates to burners, and more particularly, to a non-clogging horizontal combustion chamber. Background technique [0002] The traditional biomass pellet burner has a flat-bottomed fixed grate at the bottom, and the combustion uses a blower to force the air from under the grate. This kind of grate needs a certain gap to meet the oxygen supplement during the combustion process of biomass fuel. However, during the combustion process, biomass fuel will always form coke due to incomplete combustion, so it is necessary to deal with coke continuously to prevent coking and cover the fixed grate completely, otherwise black smoke will appear. Disposal will cause the furnace to go out. However, even if a non-coking fuel is selected, a large amount of ash will accumulate on the grate after long-term operation, causing the effective fuel area of ​​the grate to become smaller, and the fuel cannot be fully burned.

Problems solved by technology

[0002] The traditional biomass pellet burner has a flat-bottomed fixed grate at the bottom, and the combustion uses a blower to force the air from under the grate. This kind of grate needs a certain gap to meet the oxygen supply of the biomass fuel combustion process. However, during the combustion process, biomass fuel will always form coke due to incomplete combustion, so it is necessary to deal with coke continuously to prevent coking and cover the fixed grate completely, otherwise black smoke will appear. Processing will cause the furnace to go out

However, even if a non-coking fuel is selected, a large amount of ash will accumulate on the grate after long-term operation, causing the effective fuel area of ​​the grate to become smaller, and the situation that the fuel cannot be fully burned gradually increases, and it is necessary to stop regularly to clean the grate
