Abstract

The invention discloses a sawdust biomass fuel, which comprises the following raw materials in parts by weight: 60 parts of wood chips, 14 parts of additives, 6 parts of attapulgite powder, 4 parts of rare earth minerals, 2 parts of oxygen enhancer, and 0.3 parts of oxygen increase synergist , 8 parts of biological asphalt, 3.5 parts of blue-green algae mud, 1.5 parts of ammonium sulfate, and the auxiliary agent is polyanionic cellulose. The wood chip biomass fuel prepared by the present invention has high combustion efficiency, good stability, is not easy to be oxidized, can be fully burned, and can reduce the generation of harmful gases. The optimal ratio is obtained, and then the wood chip biomass fuel has the best performance, high use value and good application prospect.

Description

Technical field [0001] The present invention relates to the field of biomass fuel, and more particularly to a marsh biomass fuel and a preparation method thereof. Background technique [0002] Biomass fuel refers to the combustion of biomass material as a fuel. It is generally mainly agricultural and forestry waste (such as straw, sawdust, sugar cane, rice bran, mainly distinguishing the fossil fuel, directly burning directly in the current national policy and environmental standards) Biomass belongs to high pollution fuel, only in the rural big stove, does not allow in urban use, biomass fuel application, actually mainly biological forming fuel, is a raw material, pulverized, mixed, squeezed , Drying and other processes, a new type of cleaning fuel that can directly combust directly, and the price of the international crude oil is constantly climbing, the fossil energy is facing non-renewable, and The post-production of atmospheric pollution, greenhouse gas emissions, etc. are v...
