Abstract

The invention relates to a compound biomass granular fuel. The invention aims at overcoming the problems of low ash melting point, serious coking and the like of the existing maize straw biomass granular fuel and providing a novel compound biomass granular fuel. The formula of the fuel comprises the following components by weight percent: 70-75% of maize straw powder, 24-30% of rice hull powder and 0.5-1% of calcium oxide powder. The manufacturing method comprises the following steps: firstly processing maize straws and rice hulls into fine powder by using a smashing machine; then adding the calcium oxide powder, uniformly mixing according to the stipulated weight percent; and sending into a particle forming machine for extruding the mixture into the cylindrical granular fuel with the diameter of 6-10mm. The biomass fuel is the compound biomass granular fuel with excellent combustion characteristic, high ash melting property and low fluxing trend, and can be widely applied in various biomass combustion devices.

Description

technical field [0001] The invention relates to a renewable biomass briquette fuel, which is a composite biomass particle fuel made of crop straw, rice husk and additives. Background technique [0002] At present, energy and environmental issues have become the focus of global attention. Although oil, coal and natural gas are still the main sources of fuel, with the depletion of fossil energy and the increasingly serious environmental problems, the development and utilization of clean and renewable energy has become an important issue. pressing issues. In this context, biomass energy is the only renewable energy that can be stored and transported, and its efficient conversion and clean utilization are increasingly valued by the world. [0003] Biomass energy is a natural resource that uses green plants to store solar energy in plants through photosynthesis, and is a cheap way to store solar energy. The emission of biomass energy will not exceed the amount of carbon absorbe...
