High-efficiency non-coking solid particle fuel gasification combustor

Abstract

The invention discloses a high-efficiency non-coking solid particle fuel gasification combustor. The high-efficiency non-coking solid particle fuel gasification combustor comprises a gasification combustion core (1) and a sleeve (2) outside the core. The gasification combustion core (1) is tubular as a whole. A through cavity in the gasification combustion core (1) is divided into a combustion gasification chamber (11) and a fuel gas combustion chamber (12), and an opening in the bottom of the gasification combustion core (1) is an ash outlet (13) and is also a fuel combustion-supporting air inlet. An opening in the upper portion of the gasification combustion core (1) is a flame outlet (14) and is also a solid particle fuel inlet. The sleeve (2) outside the core is tubular as a whole, the gasification combustion core (1) is sleeved with the sleeve (2) outside the core, and an annular interlayer cavity between the gasification combustion core (1) and the sleeve (2) outside the core is an intake air preheating balancing chamber (22). Gas holes are formed in the gasification combustion core (1). Practice repeatedly proves that the problem that because fuel and fuel ash coke and become blocky in a fuel duct, the fuel duct is blocked will not be caused, and the combustor is high in efficiency, capable of saving energy, environmentally friendly and free of smoke.

Description

technical field [0001] The invention relates to a stove part, mainly a solid particle fuel stove part, especially a high-efficiency non-coking solid particle fuel gasification burner; it is installed in the hearth of a solid particle fuel stove, and the solid particle fuel is In which combustion and gasification, the flame and gasification gas generated in it are fed into the furnace. Background technique [0002] Solid pellet fuel mainly includes biomass pellet fuel, mineral pellet fuel, etc. [0003] Biomass pellet fuel is referred to as biomass fuel for short. Biomass fuel is mostly agricultural waste and wood waste (stem crops, peanut shells, bark, sawdust and solid waste (furfural residue, edible fungus residue, etc.)) after processing The resulting block (mainly cylindrical) fuel has a diameter of 6-8 mm, a length of 4-5 times its diameter, a breakage rate of less than 1.5%-2.0%, and a moisture content of less than 10%-15% on a dry basis , the ash content is less tha...
