Abstract

The invention discloses high calorific value biomass pellet fuel and a preparation method thereof. The high calorific value biomass pellet fuel is prepared from the following raw material components:straw, wood chips, peanut shell, bagasse, arundo donax, bark, a biological treatment agent, paraffin, turpentine and dilute sulfuric acid. The preparation method concretely comprises the following steps: (1) mixing the straw, the wood chips, the peanut shell, the bagasse, the arundo donax and the bark, and then crushing to prepare an initial material; (2) soaking the initial material into dilute sulfuric acid, and then carrying out heating treatment; (3) adding the initial material, subjected to the heating treatment, into the biological treatment agent, oscillating for dispersing in a magnetic field environment, and then drying to obtain a dry material; (4) melting the paraffin and then adding the turpentine, mixing and then adding the dry material, and oscillating for dispersing again; (5) pouring the treated dry material into a pelletizer to obtain the high calorific value biomass pellet fuel. The biomass pellet fuel prepared by the method has the characteristics of being inflammable, high in calorific value, full in combustion, waterproof, light in weight, convenient to carry, and the like, thus being widely applied to outdoor or field heating and cooking.

Description

Technical field [0001] The invention belongs to the technical field of bioenergy, and specifically relates to a high calorific value bioparticle fuel and a preparation method thereof. Background technique [0002] Biofuels generally refer to solid, liquid or gaseous fuels composed or extracted from biomass. It can replace gasoline and diesel made from petroleum and is an important direction for the development and utilization of renewable energy. The so-called biomass refers to various organisms produced through photosynthesis using the atmosphere, water, land, etc., that is, all living organic substances that can grow. It includes, animals and microorganisms. Unlike traditional fuels such as oil, coal, and nuclear energy, this emerging fuel is a renewable fuel. Biofuels generally refer to solid, liquid or gaseous fuels composed or transformed by living organisms. It is an important direction for the development and utilization of renewable energy and has good storability and ...
