Abstract

The invention discloses a processing method a biomass fuel and relates to the technical field of biomass fuels. The processing method comprises the following steps: (1) crushing; (2) adding of a binder; (3) heating and heat insulation; and (4) shaping. The biomass fuel prepared by the processing method is high in shaping rate. Crushed materials are subject to fumigated by water vapor, and then a sodium cocoyl sarcosinate solution is adopted to soak the fumigated materials, so that the physicochemical property of the crushed materials can be greatly improved, the crushed materials are easier toshape, and the shaping rate is effectively increased. Meanwhile, cationic etherified starch is adopted to prepare a starch slurry to serve as the binder, the biomass raw materials can be shaped undera simper condition. Besides, the shaping rate, the product density and durability, and the lower calorific value of the granular fuel can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of biomass fuel, and in particular relates to a processing method of biomass fuel. Background technique [0002] As the reserves of coal, oil, and natural gas on the earth become less and less, it is urgent to find energy sources that can replace coal, oil, and natural gas. As we all know, the earth provides humans with extremely rich plant resources, and some of these plants have always been used by humans as fuel. However, it is still difficult to directly use plants as fuel to replace coal, oil, and natural gas. The main reason is that these plants have relatively low combustion value, short combustion time, large storage space, perish easily, and high transportation costs. Contents of the invention [0003] The object of the present invention is to provide a processing method of biomass fuel aiming at the existing problems. [0004] The present invention is achieved through the following technical so...
