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 preparation of composite biomass fuel. The preparation comprises: drying mulberry twigs in the sun and adding the dried mulberry twigs in a pulverizer for pulverization to obtain mulberry twig powder having the size in a range of 40-60 mesh; adding mulberry twig powder, magnesium oxide, manganese slag, perlite and cerium nitrate in a stirrer and adding a proper amount of water for stirring to obtain paste; putting the paste in a muffle furnace and performing roasting in a temperature range of 600-800 DEG C for 2-3h to obtain a carbide; uniformly mixing the carbide with a petroleum resin and epoxy asphalt to obtain a mixture, conveying the mixture to a forming machine, and performing extrusion forming in a temperature range of 120-140 DEG C at the pressure of 80-100 Mpa to obtain formed fuel; and drying the formed fuel, cooling the formed fuel to the room temperature, and performing packaging to obtain the biomass fuel. The preparation has advantages of simple technology, low energy consumption, high production efficiency and forming rate, and low cost. The obtained biomass fuel is small in density, high in calorific value, less in ash, small in inner gap and good in moisture resistance, is not loose, and can be stored for a long time. The preparation is suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of biomass fuel processing, in particular to the preparation of a composite biomass 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 abandone...
