Clean biomass fuel and preparation method thereof

Abstract

The invention discloses clean biomass fuel and a preparation method thereof. The clean biomass fuel comprises the following raw materials in parts by weight: 40 to 70 parts of peanut shells, 15 to 35parts of wheat straws, 15 to 35 parts of soybean straws, 15 to 35 parts of tea-oil tree shells, 0.5 to 5 parts of an antichlor, and 2 to 8 parts of a sulphur fixing agent. The clean biomass fuel is energy-saving, environmentally friendly, high in combustion efficiency, calorific value and ash fusion point, not easy to cause ash erosion and soot formation, reduces corrosion to combustion equipment,can replace fuel, such as raw coal, liquefied petroleum, natural gas and firewood, and is widely applied to daily stoves and various boilers.

Description

technical field [0001] The invention relates to a clean biomass fuel. Background technique [0002] With the continuous development of society and the shortage of energy, the shortage of traditional energy such as oil, natural gas and coal is becoming more and more serious. Biomass energy, as a new energy source, has become an energy source with great development potential among new energy sources due to its renewable and zero-carbon emission characteristics. In the existing biomass energy, the heat generated by combustion is low, and the residue after combustion is serious, and the production cost is too high, which is not conducive to production and use. [0003] my country is rich in biomass resources. Currently, the resources available for utilization and development mainly include: crop straw, rice husk, chaff, resin, sawdust, leftovers from wood processing, animal manure, firewood, municipal solid waste, etc. Biomass energy has the dual attributes of being renewable ...

AI Technical Summary

Problems solved by technology

Biomass fuel has the advantages of high density, small volume, and less pollutant emissions. However, compared with traditional fossil energy, the energy density of biomass fuel is still low, the combustion is insufficient, and the combustion efficiency is low; in addition, because it is rich in alkali Metals and chlorine elements are easy to cause ash fusion. During the process of biomass combustion and gasification utilization, there will be two main problems due to ash fusion: ① At high temperature, the ash will become molten and form slag, which is bound in the gasifier. ②For biomass fixed bed combustion and gasification technology, the temperature in the furnace should not be too high. If the temperature rises, sintering will immediately occur in the furnace and damage the The air permeability inside the bed will block the gas path and produce no gas when it is serious

At present, the existing biomass fuels still cannot avoid the problems of low combustion efficiency and serious corrosion of equipment. Therefore, at this stage, the development of a clean and efficient biomass energy with high combustion efficiency and high ash melting point has become an urgent problem to be solved.
