Problems solved by technology

However, there are still major problems in my country's biomass briquette fuel. The processing technology is complicated, difficult, energy-consuming, and costly; the real calorific value, moisture content and ash content of briquette fuel are difficult to control; , easy to accumulate ash, so that the fuel combustion is insufficient, not only pollutes the environment but also corrodes the production equipment; because the raw material for processing and granulation is high-fiber material, the raw material is loose, the size and material are diverse, and it is difficult to press into dense particles when the particles are formed. shape; the rough surface and various shapes of the formed particles also affect the sales volume, these problems seriously restrict the large-scale production of biomass briquettes

Abstract

The invention discloses a high-efficiency biomass solid pellet fuel. The high-efficiency biomass solid pellet fuel is prepared from corncobs, magnesium oxide, calcium carbide slag, starch, lanthanum oxide, petroleum resin and polyurethane asphalt according to a weight ratio of 100:5-10:5-8:6-10:3-5:5-8:4-6 through crushing, molding and drying processes. The calorific value of the prepared biomass solid pellet fuel product is 24-28MJ/kg, the ash content of the product is 2.5-4.0%, the water absorption rate of the product is 8-10%, and all performances of the product are better than those of current commercial products. A preparation method of the biomass solid pellet fuel has the advantages of simple process, low energy consumption, low production efficiency, high molding rate and low cost.

Description

technical field [0001] The invention relates to the technical field of biomass fuel processing, in particular to a high-efficiency biomass solid briquette fuel. Background technique [0002] For a long time, fossil fuels such as oil, natural gas and coal have been the main energy consumed by human beings, and have made great contributions to the prosperity of human economy, social progress and improvement of living standards. However, since mineral resources such as coal, oil and natural gas are non-renewable, the resources are limited and are facing the danger of being gradually depleted. In recent years, energy and environmental issues have become increasingly prominent, energy prices have continued to rise, and the research and development of bioenergy has become a hot spot around the world. my country is a large agricultural country with abundant biomass resources. However, the utilization rate of crop leftovers is only 20-30%, and about half of the crop waste is aband...
