Pure biomass barbecue charcoal and manufacturing method thereof

Abstract

The invention discloses pure biomass barbecue charcoal and a manufacturing method thereof. The pure biomass barbecue charcoal consists of the following components in parts by weight: 0-80 parts of bamboo chip charcoal powder, 0-70 parts of wood chip charcoal powder, 20-80 parts of cotton stalk charcoal powder, 20-25 parts of adhesive and 1-2 parts of boron mud, wherein the adhesive is prepared by uniformly mixing carboxymethyl cellulose, alpha starch and water according to a weight ratio of 0.5:1:5. The manufacturing method comprises the following steps of: preparing the wood chip charcoal powder, bamboo chip charcoal powder, cotton stalk charcoal powder and an adhesive; mixing the bamboo chip charcoal powder, wood chip charcoal powder and cotton stalk charcoal powder, and adding the boron mud for uniformly mixing and stirring; and finally, adding the adhesive, fully and uniformly stirring, pressing the mixture in a molding abrasive tool, demolding to obtain the molded carbon block, drying to the moisture content of 2-5 percent, and obtaining the pure biomass barbecue charcoal which is non-toxic, safe, environment-friendly, easily ignitable and high in heat value. The pure biomass barbecue charcoal has the characteristics of simple manufacturing method, wide raw material source and low production cost.

Description

technical field [0001] The invention relates to a civil solid fuel, that is, pure biomass barbecue charcoal and a production method thereof. Background technique [0002] Zhejiang and other places in my country have already started to produce bamboo charcoal, charcoal and machine-made charcoal, but most of them are produced in earthen kilns, with low technical content and high defective rate. Machine-made charcoal has the disadvantage of being difficult to ignite in use. [0003] For other easy-to-ignite barbecue charcoal, a mixture of nitrates is added as an oxidizing combustion aid, and NO will be produced when burning X and other harmful gases; CN101070499's "straw charcoal biomass environmental protection honeycomb ball" and CN101550370A's "environmentally friendly and flammable barbecue charcoal and its production method" have both explored and improved in this respect. The former uses straw charcoal as the main material, because straw charcoal The carbon content is ...
