Anticorrosion flammable sawdust-based biomass particles and preparation method thereof

Abstract

The invention discloses anticorrosion flammable sawdust-based particles. On one hand, the sawdust is subjected to carbonization treatment and then modification, the toughness and density of inorganic carbon particles are improved, the combustion heat value of sawdust carbon residue is increased, volatile components in the combustion process are reduced, and the sulfur content of the discharged waste gas is low while peculiar smell is avoided; on the other hand, by fermenting the peanut shells and ramulus mori sawdust, the structure layer of the raw material is changed to form a dense structure, high-content organic matter is obtained, and the organic matter composition is increased; by adding modified bentonite, rape seed cake residue and gypsum for further fermentation, the combustibles in the organic raw material are increased; and finally, through compatibility with other effective auxiliaries for extrusion moulding, the prepared sawdust-based biomass particle fuel is anticorrosion and flammable, the combustion value is relatively high, the combustion time is long, the storage space is small, the transport cost is low, and deterioration is avoided.

Description

technical field [0001] The invention relates to the technical field of biomass fuel, in particular to an anti-corrosion and flammable sawdust-based biomass particle and a preparation method thereof. Background technique [0002] With the increasing demand for energy, the widely used non-renewable energy such as oil, coal, and natural gas is facing the problem of depletion. In order to solve the energy crisis that mankind is about to face, it is necessary to develop renewable new energy sources to replace non-renewable fossil fuels. Biomass energy, as a cheap and clean renewable energy, is attracting more and more attention from people. As a large agricultural country, our country has comparative advantages in raw material supply, energy demand and government policy support of biomass energy. big advantage. The source of sawdust and straw is abundant, the cost is low, and the sulfur content of sawdust is very low. The biomass pellet fuel prepared from it as a raw material r...

AI Technical Summary

Problems solved by technology

However, the traditional biomass pellet fuel prepared by using sawdust and straw has many defects such as low calorific value, unsafe use of slagging boilers, excessive sulfur content polluting the environment, and large ash content.
