Problems solved by technology

However, due to the high ash content of the crop waste itself, when processed into biomass fuel, affected by the ratio of raw materials and the structure of biomass particles, the burning performance is poor, and there will still be problems of insufficient combustion and a large proportion of residual ash.

Abstract

The invention relates to the technical field of modern agricultural industry, and discloses a method for reducing the ash content of crop biomass fuel combustion. The fuel activation is enhanced, the ignition point is reduced, the ignition speed is fast, the combustion speed is fast, the combustion process is more complete, the combustion performance is improved, the combustion residual ash is reduced, and the desulfurization effect is also available, which can reduce the emission of polluting gases. The present invention effectively solves the problem. It solves the problem of large residual ash in the combustion of crop biomass dyes, improves the utilization value of crop waste and the combustion value of biomass fuel, and can realize the practical significance of maximizing the utilization of resources and protecting the environment. Technical solutions.

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 burning ash of crop biomass fuel. Background technique [0002] Biomass fuel: refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry wastes (such as straw, sawdust, bagasse, rice bran, etc.), which are mainly different from fossil fuels. In the current national policies and environmental protection standards, the 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 is made of agricultural and forestry waste as raw materials through processes such as pulverization, mixing, extrusion, drying, etc. A new type of clean fuel that can be directly burned. [0003] As a broad source of crop waste, direct combustion ...
