Abstract

The invention relates to the technical field of modern agricultural industry and discloses a method of reducing the combustion clinkering rate of a corn straw biomass particle fuel. By means of combustion characteristic and combustion principle of dynamics, prepared porous ceramic particles with an adsorption function are doped into the corn straws, so that the condition that low-melting-point compounds are generated by alkaline metal elements such as potassium and sodium in biomass ash can be prevented, so that the clinkering rate is reduced and the melting point of ash of the corn straw particle fuel is improved, and the problem that the corn straws in the combustion process are easy to agglomerate and clinker is solved. By simulating a combustion test, the prepared corn straw biomass particle fuel is not coked fully at 1300 DEG C. The method solves the problem that the clinkering rate of the existing corn straw biomass particle combustion fuel is high is solved effectively, can achieve extreme utilization of resources and practical significance of environmental protection, has application value in development of biomass energy sources, and is a technical scheme which is worth being popularized and used extremely.

Description

technical field [0001] The invention belongs to the technical field of modern agricultural industry, and in particular relates to a method for reducing the slagging rate of corn stalk biomass particle fuel combustion. Background technique [0002] Biomass fuel: refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry waste (such as straw, sawdust, bagasse, rice bran, etc.), which is mainly different from fossil fuels. In the current national policy and environmental protection standards, direct combustion of biomass is a highly polluting fuel, which is only used in large stoves in rural areas and is not allowed to be used in cities. The application of biomass fuel is actually mainly biomass briquette fuel, which uses agricultural and forestry waste as raw materials, and is made into various shapes (such as lumps, granules, etc.) through crushing, mixing, extrusion, drying and other processes. A new type of clean fuel that can be directl...
