High-strength sawdust-based biomass particles and manufacturing method thereof

Abstract

The invention discloses high-strength sawdust-based biomass particles. According to the invention, on one hand, the sawdust is subjected to charing processing and modification, the toughness and the density of the inorganic carbon particles are improved, the combustion heat value of the sawdust carbon residue is increased, the volatile component during a combustion process is reduced, the sulfur content of discharged exhaust gas is low; on the other hand, walnut shell, pine and cypress branches and hot pepper seedlings are subjected to fermentation processing, a raw materials structural layer is changed to form a compact organization structure, a high-content organic matter is formed, the composition components of the organic matter are increased, the modified dolomite powder and pineapple waste are added for continuous fermentation, the combustible matters in the organic matter raw materials are increased, other effective auxiliary agents are combined for extrusion moulding, the produced sawdust-based biomass granular fuel has the advantages of high intensity, large density, full combustion, and durable firepower, and greatly increase the gas production speed and gas production amount, through compression bonding of the biomass particles by the pineapple waste, the biomass fuels intensity is increased.

Description

technical field [0001] The invention relates to the technical field of biomass fuels, in particular to a high-strength sawdust-based biomass particle and a manufacturing 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 replaces fossi...

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.
