Problems solved by technology

[0003] The inventions with the application numbers of 201610088251.9 and 201510353869.9 disclose that the raw materials are mixed and placed in a fermentation tank for fermentation. After two fermentations, a combustion aid is added to reduce its ignition point, and finally a biomass fuel is obtained through molding and pressing. There are disadvantages of complex and troublesome fermentation technology, high cost and high cost of biomass fuel components, and long fermentation time
[0004] Biomass fuels are prepared by application numbers 201510670010.0, 201210412146.8 and other inventions. Although they can be stably molded, they are unstable after molding and cannot be maintained for a long time. They are easily affected by environmental humidity, temperature and other factors. At the same time, their combustion will produce a lot of smoke.

Abstract

The invention relates to the field of biomass fuel, in particular to a preparation method of stable biomass briquettes fuel. The method is characterized by including the following steps that firstly, raw materials are fermented after preprocessing to prepare fermentation broth, wherein an inoculant capable of decomposing cellulose is added in the fermentation process; secondly, the obtained fermentation broth is dried to obtain a dried product; thirdly, the dried product is squeezed to prepare the biomass briquettes fuel, wherein the inoculant is one of or multiple of bacillus licheniformis, bacillus subtilis, decondensation emulsion bacilli and bacillus tequilensis. By means of the technology, the aim of waste comprehensive utilization is achieved, dense smoke emission is reduced, and environment friendliness and safety are achieved. Deoiled aromatic plant leaf residues obtained after fermentation are formed more easily.

Description

technical field [0001] The invention relates to the field of biomass fuel, in particular to a method for preparing a stable biomass briquette fuel. Background technique [0002] Biomass energy has become the fourth largest energy source in the world because of its renewable, abundant resources, and environmental friendliness. It is also the only clean renewable energy that can be transported and stored. It mainly uses modern biomass energy technology to convert agricultural waste and logging residues and other raw materials are processed into end products such as biomass pellet fuel, biodiesel, and biofuel ethanol. Biomass fuel has almost no SO in the later utilization process 2 It reduces the harm of acid rain and greenhouse effect caused by the flue gas produced in the process of utilization, and makes biomass energy have a broader application prospect and development space. Therefore, the development of biomass fuel has become a human solution to energy problems and An ...
