Abstract

The invention discloses a biomass charcoal bar with high calorific value, and relates to the technical field of biology environment protection. The biomass charcoal bar is prepared by the following steps of crushing corn straw, so as to obtain the corn straw powder; treating the corn straw powder by a silane coupling agent solution, modifying the treated corn straw powder by polymer, and carbonizing the product by a pyrolyzing furnace, so as to obtain biomass charcoal; pressing the biomass charcoal into bars to obtain charcoal bar. The biomass charcoal bar prepared by the invention has the advantages that the combustion property of the forming fuel is enhanced; after compression molding is performed, the formed charcoal bar has certain external force-resisting ability; the easiness in crushing in the transportation or storage process is avoided, discharged smoke and dust in the combustion process is little, ash slag after combustion is little, the combustion property is stable, the slag forming-resistant ability is strong, and the slag forming and corrosion in the straw combustion process are effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of biological environmental protection, and in particular relates to a high calorific value biomass carbon rod. Background technique [0002] my country is a large agricultural country. According to statistics, about 600-700 million tons of rice, wheat, corn and other crop straws are produced every year. As agricultural production waste, these straws are usually directly incinerated, resulting in a large amount of smoke and dust, leading to serious air pollution, often causing traffic accidents and even fires, seriously affecting people's lives. Therefore, how to rationally utilize such a large amount of waste straw is not only a research hotspot in my country, but also worldwide. At present, the utilization of waste straw at home and abroad mainly includes returning to the field, fermentation and gasification, power generation, and production of biomass fuel. Among them, the use of straw to produce biomas...
