Abstract

The invention discloses an anti-slagging biomass solid granular fuel and solves a problem that a biomass solid granular fuel in the prior art is liable to slag and is low in combustion efficiency. The anti-slagging biomass solid granular fuel is prepared from following raw materials, by weight, 60-70 parts of crop straws, 10-15 parts of wood chips, 5-10 parts of bagasse, 3-5 parts of a combustion-promoting agent and 1-3 parts of an anti-slagging agent. The anti-slagging biomass solid granular fuel is simple in components, reasonable in formula, low in cost, high in combustion efficiency and low in slagging rate.

Description

technical field [0001] The invention relates to a biomass fuel, in particular to an anti-slagging biomass solid particle fuel. Background technique [0002] Biomass solid briquette fuel refers to a solid fuel that uses agricultural production residues such as crop straws and is compressed into a specific shape by special equipment to increase its density. When using CO 2 Net emissions are approximately zero, NO X , SO 2 The low emissions are conducive to reducing the phenomenon of straw burning in vast rural areas and improving the atmospheric environment. [0003] However, due to the inherent high content of alkali metal elements in biomass such as straw, the ash melting point is low, and the slagging phenomenon is serious during use, which not only reduces the combustion efficiency, but also causes serious corrosion to the combustion equipment and reduces the performance of the combustion equipment. and service life. [0004] For example, the application publication...
