Problems solved by technology

[0004] The above-mentioned raw materials have not been used as fuel reports except cow dung. The reasons are as follows: first, these raw materials have a high water content and are not easy to burn directly; It cannot be directly used as fuel; second, even if the general treatment method is used to dry and then compress, the calorific value of the obtained product is still very low, and the economic value is not high; third, no suitable material compression method has been developed to obtain suitable compression Ratio of fuel, inconvenient to burn

Abstract

The invention discloses a biomass fuel belonging to the technical field of renewable energy. The biomass fuel comprises at least one of vinasse, bacterium buds, camphortree leaves and cow dung; when the biomass fuel comprises two and more than two of the components, the components are mixed in any mass ratio, and the components have 10-25 percent of water content in terms of the mass ratio. The invention also discloses a preparation method of the biomass fuel. Four raw materials are independently prepared or prepared in a mixing way; and the process of independent preparation comprises the following steps of: firstly respectively adding coalification agents to carry out coalification treatment on the vinasse, wherein the added amount of the coalification agents is 1-3 percent in terms of the mass ratio, and the time of the coalification treatment is 8-10 hours; then airing or drying till the water content is 10-25 percent; and finally grinding for forming. The biomass fuel has the advantages of high calorific value, environmental friendliness, energy saving, simple preparation method, good economic benefit and recycling.

Description

technical field [0001] The invention relates to a biomass fuel and a preparation method thereof. Background technique [0002] According to the forecast of the International Renewable Energy Organization, the reserves of underground oil, natural gas and coal can only be used for about 60 years according to the current exploitation and utilization rate, and the energy crisis is getting worse. In order to solve the energy crisis, people have long started to develop renewable energy and clean energy, such as wind energy, solar energy, etc., but due to the dependence on equipment and the limitation of conversion and utilization technology, the development and utilization of these energy sources still need to be further improved. On the other hand, the development of biomass energy is a development direction of renewable energy in the future. In particular, the use of industrial, agricultural and other waste materials for recycling, development and utilization has become a hot s...
