This invention provides a
biomass fuel and its preparation method, belonging to the field of waste utilization technology. This invention mixes different waste materials to prepare
biomass raw materials, and simultaneously utilizes microbial strains to transform the organic
flame retardants contained in the waste raw materials into new flammable agents through
biochemical reactions. The prepared
biomass fuel has high calorific value, low
smoke and dust, and excellent
combustion performance, making
rational use of various waste materials, and is
environmentally friendly, efficient, and energy-saving. The results of the embodiments show that the biomass fuel prepared by this invention has a calorific value of 35.6 MJ / kg, a calorific value of 4100 cal / g, a
combustion efficiency of 99.1%, and low
smoke and dust.
