Abstract

The invention discloses an environment-friendly biomass granular fuel, which comprises the following components in part by weight: 80-85 parts of sawdust, 5-10 parts of sludge and 0.1-1 part of illegally recycled waste cooking oil. A preparation method of the environment-friendly biomass granular fuel comprises the following steps: drying the sawdust and the sludge, adding the illegally recycled waste cooking oil to the sawdust and the sludge, agitating the mixture uniformly, and processing the mixture into cylindrical grains under conditions of a high temperature and a high pressure. By using the biomass granular fuel provided by the invention, the production cost is decreased; the energy consumption is decreased; the combustion heat value is high; the combustion time is long; the wear of a machine is reduced; the environment is protected effectively; the fuel problem is solved; simultaneously, the health is also protected; the biomass granular fuel is environment-friendly; the cost is decreased; after the biomass granular fuel is combusted, waste residues can be returned to the nature to be used as a fertilizer, and also can be used as a raw material of an environment-friendly brick; and the resource utilization and the harmless treatment of waste materials such as the sludge, the illegally recycled waste cooking oil and the like are achieved.

Description

technical field [0001] The invention relates to the field of new energy, in particular to an environmentally friendly biomass particle fuel and a preparation method thereof. Background technique [0002] With the development of social economy, the deterioration of the environment is also increasing. Low-carbon economy has also become a topic of widespread concern. At the same time, for human beings who are suffering from global warming, the development of low-carbon economy is also a solution A good way, low-carbon economy also drives the development of energy-saving and environmental protection industries. In recent years, with the rise of energy prices and the country's emphasis on rural ecological environment and farmers' indoor air quality, the scale and commercialization of my country's biomass briquette fuel industry have increased year by year, and the market has developed rapidly. Vigorously developing the biomass briquette fuel industry and utilizing agricultural a...
