Problems solved by technology

At present, the biomass solid molding raw material processed with eucalyptus bark has the characteristics of less slagging, but the calorific value is low and the ash content is large, which has become the main factor hindering the popularization and application of eucalyptus bark biomass solid molding fuel; while the use of bamboo residues The calorific value of the processed biomass solid briquette fuel is very high, but the slagging is more than that of eucalyptus bark, and the deposition and corrosion of the heating surface of the boiler are serious

Abstract

The invention relates to a biomass fuel, particularly to a compound biomass fuel briquette to solve the problems of low heat value and large ash content of single biomass solid fuels. The briquette comprises, by weight, 70%-74% of eucalyptus bark powder, 24%-30% of bamboo bran and 2%-3% of calcium oxide powder. The preparation method includes processing eucalyptus barks and bamboos into the eucalyptus bark powder and the bamboo bran through a pulverizer, adding the calcium oxide powder, evenly mixing the raw materials according to regulated weight ratio, and extruding the mixture into the fuel briquette in a square or cylindrical shape by using extrusion forming mechanical equipment. According to the briquette and the preparation method, the defects of low heat value and large ash content of eucalyptus bark biomass solid fuels can be overcome, coking and deposit corrosion of pure bamboo bran biomass solid fuels are reduced simultaneously to overcome the defect of the single biomass solid fuels, and therefore fuel characteristics are improved.

Description

technical field [0001] The invention relates to a biomass fuel, in particular to a composite biomass fuel briquette and a preparation method thereof. Background technique [0002] Biomass solid briquette fuel has the advantages of easy storage, convenient transportation and use, clean and environmentally friendly, and high combustion efficiency. As an excellent clean renewable energy, it has attracted more and more countries' attention. Biomass energy has completely replaced traditional energy sources in some western developed countries, and has made significant contributions to the energy security and environmental improvement of western developed countries. my country has started research on biomass energy since the 1990s, and has achieved certain results at this stage. [0003] There are extremely rich biomass resources of eucalyptus bark and bamboo processing residues in southern my country, which is also the focus of developing and utilizing biomass energy in this area...
