Compound type sawdust-based biomass particles and making method thereof

Abstract

The invention discloses compound type sawdust-based biomass particles. On one hand, sawdust is subjected to carbonization treatment and modification in sequence, the toughness and density of inorganic carbon particles are improved, the combustion heat value of sawdust charcoal residues is improved, volatile components in the combustion process are reduced, and emitted exhaust gas is low in sulfur content; on the other hand, poplar leaves and pine tree bark are subjected to fermentation treatment, structural layers of the raw materials are changed to form a compact organization structure and form high content organic matter, and the organic matter composition is improved; modified pyrophillite powder, amygdalus comnnis husk and potato pulp are added for continuous fermentation treatment, the combustible content in organic raw materials is increased, compatibility with other effective auxiliaries is achieved, and extrusion forming is conducted. By means of blending and optimization of the formula and the collaborative combustion action of coke nut particles and biomass, the combustion efficiency can be greatly improved, ignition temperature is lowered, the combustion time is long, and no harmful gas or acid gas emits after combustion.

Description

technical field [0001] The invention relates to the technical field of biomass fuels, in particular to a composite 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 fossil fu...

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.
