Abstract

The invention discloses a low-corrosivity environment-friendly biomass solid briquette fuel which is prepared by the following steps: pulverizing a biomass raw material, mixing the pulverized biomass raw material with fuel additives, drying, and carrying out hot pressing. The biomass raw material is composed of crop straws, peanut shells and shoddy and little fuelwood; the fuel additives are composed of a dehydrating agent, a combustion improver and a solid absorbent; and the weight ratio of the biomass raw material to the fuel additives is 100:(4-9). By using the shoddy and little fuelwood containing abundant lignin as the main biomass raw material, the abundant lignin performs the function of bonding under the combined actions of temperature and pressure, thereby enhancing the bonding strength and durability of the biomass solid briquette fuel; and thus, the biomass solid briquette fuel can not easily become loosened, and has favorable completeness in the transportation process. Nano aluminum powder used as the combustion improver can greatly enhance the combustion efficiency and combustion stability. Kaolin powder and/or coal gangue powder are/is used as the solid absorbent, thereby greatly improving the soot deposition and corrosion conditions of the heating surface, and prolonging the service life of the combustor.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of biomass fuels, in particular to a low-corrosion and environment-friendly biomass solid briquette fuel. [0003] 【Background technique】 [0004] In recent years, with the rapid and continuous development of the global economy, the demand for energy in various countries is increasing day by day, resulting in the rapid consumption of existing fossil energy, and has gradually faced the crisis of energy depletion, and the use of fossil energy has seriously polluted the environment, leading to an increasingly harsh global environment. Biomass energy is a renewable, environment-friendly clean energy with good industrialization prospects and huge development potential. It occupies an important position in the energy structure of various countries. Among them, biomass solid briquette fuel is biomass One of the important ways of energy conversion and utilization. Biomass solid molding fuel is rich in raw m...
