Biomass fuel with good formability

Abstract

The invention relates to environment-friendly biomass fuel with good formability. The biomass fuel is renewable biomass fuel free of any harmful substance, which is prepared by mixing wood dust powder and an additive, wherein the additive is high clay having high viscosity and strong adsorptive power; and the biomass fuel is prepared by mixing the wood dust and the additive according to a ratio of 9:1. The high clay additive is beneficial to formation of wood dust particles, and the multiporous fiber-like structure of the high clay additive can adsorb tar in flue gas from a heating system in the biomass fuel processing course, thereby preventing the tar from being attached to a granulator and a chimney and further avoiding influencing the granulating effect. Besides, the additive also solves the problem that the tar is difficult to remove and clean.

Description

technical field [0001] The present invention relates to the technical field of solid fuels, and more specifically can be described as a biomass fuel mixed with additives. Background technique [0002] Biomass fuel refers to the processing and compression of agricultural and forestry waste such as straw, weeds, sawdust, shrub branches and even fruit shells and peels into regular-shaped combustion particles to solve the problems of biomass raw material transportation, storage and combustion. Since the material to be processed and granulated is a high-fiber material, and the raw material is loose, with various sizes and materials, it is difficult to press into a dense granule during granulation. [0003] In recent years, people have also studied a lot of biomass energy and its high-efficiency compression molding methods. For example, in the Chinese invention patent with the patent application number 200710034411.2, a biomass pellet fuel and its production method are disclosed. ...

Problems solved by technology

[0003] In recent years, people have also studied a lot of biomass energy and its high-efficiency compression molding methods. For example, in the Chinese invention patent with the patent application number 200710034411.2, a biomass pellet fuel and its production method are disclosed. In order to make the product molding effect Well, potatoes or sweet potatoes are added as a binder, the production process is complicated and the production cost is relatively high

Another example is an invention patent with the Chinese patent application number 200510076609.8, an economical biomass fuel (environmentally friendly charcoal) production method, which is characterized in that the mechanism charcoal is composed of discarded biomass materials and some combustion aids, and biomass waste accounts for 95%, and the rest is chemical material combustion accelerant, although this invention can burn without smoke and taste, and can burn fully, but it uses chemical components, and its combustion still has problems such as environmental pollution
