Problems solved by technology

[0003] The traditional biomass densification molding technology is to directly crush waste and hot-press molding to produce pellet fuel. The obtained pellet fuel has low strength, and the surface of the product is easy to crack during storage and transportation. After burning, the ash is easy to form glassy hard slag. Condensation on the inner wall of the boiler, resulting in hard-to-remove ash and slagging problems

Abstract

The invention relates to the technical field of biomass fuel production, and more particularly relates to a wood biomass fuel and a production method thereof. The fuel comprises the following raw materials by mass fraction: 70-90% of forestry waste, 5-10% of a binder, 0.5-10% of a combustion promoter and 1-15% of an anti-slagging agent. According to the invention, the combustion efficiency, the mechanical strength and the slagging resistance of the wood biomass fuel are improved by introducing composite functional additives.

Description

technical field [0001] The invention relates to the technical field of biomass fuel production, and more specifically relates to a woody biomass fuel and a production method thereof. Background technique [0002] Forestry waste is a large amount of waste generated during the growth and processing of forest crops, such as residual branches, leaves, wood chips and leftovers from wood processing. my country is rich in forestry waste resources, and hundreds of millions of tons of residual waste are produced every year due to production activities such as timber harvesting and processing. These wastes are small in density and fluffy in size, and can be processed into solid fuels for power generation through biomass densification technology Plants and used as fuel for industrial boilers, etc. [0003] The traditional biomass densification molding technology is to directly crush waste and hot-press molding to produce pellet fuel. The obtained pellet fuel has low strength, and the s...
