Abstract

The invention provides biomass fuel and a preparation method thereof. Quartz sand is added into a biomass raw material; on one hand, the quartz sand can be used as a core to capture fly ash, so that combusted ash is gathered and thus is not dispersed on the surface of a furnace wall pipeline, and the problem that coke is formed on a furnace wall is prevented; on the other hand, the quartz sand andmetakaolin can be used for improving the stability of whole condensation of the biomass fuel and a phenomenon that the biomass fuel is collapsed so that inner fuel is not completely combusted when alarge batch of fuel is combusted and the combustion utilization rate is influenced is avoided. According to the biomass fuel provided by the invention, galling treatment is carried out on the surfaceof the biomass fuel in a processing process, so that the roughness of a biomass surface is higher; a phosphoric acid solution is sprayed, so that the combustion rate is further increased and the biomass fuel is convenient to combust and ignite.

Description

technical field [0001] The invention relates to the technical field of biomass fuel preparation, and more specifically, to a biomass fuel and a preparation method thereof. Background technique [0002] At present, coal-fired boilers dominate my country's industrial boilers, and low fuel costs are a major advantage of industrial coal-fired boilers. According to decades of practical experience, coal-fired boilers have two unavoidable disadvantages: first, the thermal efficiency of the boiler is low, generally around 70%, and the fuel combustion is insufficient; second, the blackness of the flue gas is large, and the content of SO2 and NOX is high , serious environmental pollution. Therefore, the development of clean energy and global climate change have become the focus of common attention of the international community. In the 200 years of industrialization in the world, only developed countries with a population of less than 1 billion have achieved modernization, but global...
