Problems solved by technology

The energy consumed by the latter two processes accounts for 25-35% in the whole process of granulation. In addition, the wear and tear on the machine is relatively large during the forming process, so the manufacturing cost of traditional granule forming machines is relatively high.

Abstract

The invention discloses a method for manufacturing bio-fuel from radix paeoniae alba extraction waste. The method includes steps of S1, drying radix paeoniae alba residues and then uniformly mixing the radix paeoniae alba residues and sawdust with one another to obtain mixtures; S2, pressing the mixtures to obtain bio-fuel lumps with the density of 0.8-1.2 kg / m<3>. The method for manufacturing the bio-fuel from the radix paeoniae alba extraction waste has the advantages that the bio-fuel manufactured by the aid of the method is easy to industrially produce and use, has high combustion values, is easy to clean and free of boiler corrosion and does not contain sulfur or phosphorus, and the costs can be reduced for enterprises.

Description

technical field [0001] The invention relates to the technical field of biofuels, in particular to a method for producing biofuels by extracting waste from Radix Paeoniae Alba. Background technique [0002] The research and development of bioenergy technology has become one of the major hot topics in the world, and has attracted the attention of governments and scientists around the world. Many countries have formulated corresponding development and research plans, such as Japan's Sunshine Plan, India's Green Energy Project, and the United States' energy farm, among which the development and utilization of bioenergy occupies a considerable share. Many bioenergy technologies and devices abroad have reached the level of commercial application. Compared with other biomass energy technologies, biomass pellet fuel technology is easier to achieve large-scale production and use. The convenience of using bioenergy pellets is comparable to that of gas, fuel oil and other energy sourc...
