Biomass burner and use method

Abstract

The invention relates to a biomass burner and a use method. The biomass burner is arranged inside a boiler cavity, biomass fuel is scattered at the center of a stirring disc, a motor I drives the stirring disc to rotate, a plurality of stirring rods of the stirring disc lay the biomass fuel on the surface of a burning disc, meanwhile, an air supplying motor conveys high-pressure air to an air cavity tray, the concentrated bunch high-pressure air is turned into high-pressure spiral air by air uniforming protective blocks to be conveyed to a burning space inside a boiler, oxygen filling aid-combustion is performed on the biomass fuel, the burned biomass fuel is circled and blocked by an ash block when entering the burning disc step by step to perform tail burning namely the carbon burning stage, the multiple stirring rods of the stirring disc stir residue after tail burning into an ash discharging box again, and the biomass fuel residue is smashed and discharged by two residue breaking devices. The biomass burner and the use method have the beneficial effects that the problem perplexing straw fuel burning for a long time of coking, slagging and being unable to be popularized and applied is solved, the purpose of innocuous treatment is realized, and discharged flue gas reaches the standard of clean energy.

Description

technical field [0001] The invention relates to a biomass burner and its use method, which is a burner used in various industrial and civil furnace bodies such as heating boiler body, steam furnace body, hot air kiln body, normalizing kiln body, etc. It is also used in the harmless treatment of medical and industrial, civil and other sludge, garbage, combustible waste, organic waste, pharmaceutical residues and various product residues, etc., in addition to various chemical agents and garbage disposal, Almost covers the treatment of various organic matter. Background technique [0002] At present, most of the existing biomass fuel boilers in China are transformed from traditional coal-fired boilers, which generally have disadvantages such as low combustion efficiency and high exhaust temperature, especially the fuel characteristics that cannot adapt to the high sugar content of straw, and serious problems will occur during the combustion process. The slagging phenomenon mak...

Problems solved by technology

[0002] At present, most of the existing biomass fuel boilers in China are transformed from traditional coal-fired boilers, which generally have disadvantages such as low combustion efficiency and high exhaust temperature, especially the fuel characteristics that cannot adapt to the high sugar content of straw, and serious problems will occur during the combustion process. The phenomenon of slagging makes it difficult for these boilers to be put into practical application
