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 method for preparing biomass briquetting fuel from sisal hemp residues. Sisal hemp residue powder, magnesium oxide, manganese ore slag, starch, cerous sulfate, sodium carboxymethylcellulose mucilage and epoxy asphalt with the weight ratio of 100:(8-12):(5-10):(10-15):(2-4):(10-15):(5-8) are adopted as raw materials, and the biomass briquetting fuel is prepared through the procedures of smashing, forming, drying and the like. The method has the advantages that the preparation process is simple, energy consumption is low, production efficiency is high, the forming rate is high, and cost is low, the prepared biomass fuel is low in density, high in heat value, low in ash content, not prone to looseness, good in moisture resistance, capable of being saved for a long time and suitable for industrial production, and internal gaps of the product are small.

Description

technical field [0001] The invention relates to the technical field of biomass fuel processing, in particular to a method for preparing biomass briquette fuel from sisal residue. 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 c...
