Problems solved by technology

However, the briquette fuel technology using biomass as raw material in the forestry field is still under continuous research. So far, there are not many reports on the success of the briquette fuel technology using biomass as raw material in the forestry field, especially for forest waste. Adding any additives (such as softeners, binders, etc.) to the development and utilization of briquettes is rarely reported, and there are even fewer reports on the use of waste briquettes after logging for industrial production.

Abstract

The invention discloses a forest waste forming fuel and a processing method thereof. The forming fuel is formed by that single forest raw material is smashed into particles or various forest raw materials are smashed into particles and raw materials of the same-grade granularity or multi-grade granularity are smashed into particles and mixed, and then the mixture is extruded and is mutually embedded and twisted into a cylinder or a polygonal strip shape, wherein the sections of two ends of the cylinder or the polygonal strip shape are irregular sections. The processing method comprises the following technical steps of: collecting the raw material; smashing the raw material; smashing the raw materials into particles, and drying until the moisture content is 15-25%; feeding the dried raw material into a forming machine to be compressed and formed; classifying the formed product; classifying and packaging the classified formed product; and labeling and putting into storage. The forest waste forming fuel has the advantages that the internal cohesion of the forming fuel is good, the advantages of no carbon monoxide, flammability, high heat value, good firepower, no toxin and no pollution of the forest raw material are kept on the premise that no external additive is added, and the forest waste forming fuel is an ideal biomass solid fuel.

Description

Technical field: [0001] The invention relates to a biomass briquette fuel and a processing method thereof, in particular to a biomass briquette fuel without any additives and a processing method thereof, specifically to a forest waste briquette fuel and a processing method thereof. Background technique: [0002] Biomass molding fuel, also known as biomass compressed fuel, refers to the fuel that compresses biomass through special equipment. It is extruded from loose orange stalks, straw, shells, wood chips and other agricultural and forestry waste. A new type of modern biomass fuel. The national "National Economic and Social Development Eleventh Five-Year Plan" clearly stated that it is necessary to accelerate the development of biomass energy, and pointed out that "strengthening the development and utilization of renewable energy is the only way to deal with the increasingly serious energy and environmental problems. The only way for society to achieve sustainable developm...
