Abstract

The invention provides a biomass moulded coal and a preparation method thereof, relates to a fuel coal, and solves the problems of coal slurry such as poor quality, insufficient burning, lower heat and high cost while the coal slurry is adopted in most of the existing moulded coal. The biomass moulded coal is prepared from the following raw materials by weight percent: 65-75% of the coal slurry, 23-33% of straw carbonized powder, 0.5-1% of adhesive and 1-2% of water. The preparation method comprises the following steps: carbonizing straw by a straw carbonized oven to obtain straw carbonized powder, mixing and stirring evenly the straw carbonized powder with the coal slurry, the adhesive and the water by weight percent, and putting the mixture into a coal briquetting machine to obtain the biomass moulded coal. In the invention, biomass is added into the coal slurry, so that waste plants improve the moulded coal quality. The invention has the advantages of sufficient burning, high heat improved by 7.6-15% compared with the existing coal slurry-type coal, less energy consumption and low cost.

Description

technical field [0001] The invention relates to fuel briquette and its preparation. In particular, it relates to biomass briquettes and a preparation method thereof. Background technique [0002] At present, common briquettes are made from coal. But coal resources are limited, and it is a serious waste of energy. Most of the existing briquettes use coal slime. Because the coal quality of coal slime is poor and the combustion is not sufficient, the calorific value is low and the cost is high. Contents of the invention [0003] The present invention solves the problem that most of the existing briquettes use coal slime by adding biomass to the coal slime. The coal quality of the coal slime is poor and the combustion is insufficient, so the calorific value is low, and a biomass briquette and Preparation method, the concrete technical scheme that solves this problem is as follows: [0004] A kind of biomass briquette of the present invention is prepared by mixing the follow...
