Abstract

The invention discloses a biomass granular fuel. The biomass granular fuel comprises the following components in parts by weight: 30-35 parts of corn straw, 15 to 20 parts of poplar sawdust, 20 to 30parts of cassava stems, 3-5 parts of coffee grounds, 0.3 to 0.5 part of a leveling agent, 0.5 to 1 part of a sulfur fixing agent, 4-6 parts of a flame accelerator and 1-3 parts of an additive. The rawmaterials of the biomass granular fuel are wide in source and belong to waste; so the waste is turned into the valuable, pollution to the environment is treated, an ecological environment is protected from the source, certain ecological benefits are obtained, cost is low, income can be increased, and good economic benefits are obtained.

Description

technical field [0001] The invention relates to the technical field of bioenergy, in particular to a biomass particle fuel. Background technique [0002] The development of today's society is inseparable from energy. Traditional energy is mainly obtained by burning fossil fuels. However, fossil fuels are non-renewable fuels, and fossil fuels are likely to cause air pollution during the combustion process. Therefore, combined with With the advancement of science and technology and the development of social productivity, pellet fuel made of biomass has been gradually popularized and used by people. [0003] Biomass new energy refers to fuel ethanol and biodiesel produced from biological resources, which can replace gasoline and diesel produced from petroleum, and is an important direction for the development and utilization of renewable energy. , peanut shells, corn cobs, rice husks, branches, leaves, hay and other fuels that are directly used by compression molding. Biomass ...
