Problems solved by technology

The existing pellet fuel still has the following disadvantages: because the raw materials are all crops, the content of alkali metal elements is high, resulting in a low ash melting point, and serious slagging during use; when the fuel is burning, oxygen is not easy to enter the interior of the fuel center, resulting in poor combustion of the fuel. Adequate, low burn rate issues

Abstract

The invention relates to the technical field of biomass fuel and specifically relates to environment-friendly biomass particle fuel and a processing method. The particle fuel is prepared from the following raw materials in parts by weight: 45 to 65 parts of woodwork waste mixture, 10 to 20 parts of mulberry stalk, 5 to 15 parts of straw, 5 to 8 parts of tobacco stem, 3 to 5 parts of flame accelerator, 2 to 3 parts of anti-slagging agent and 1 to 2 parts of sulfur fixing agent. The invention further discloses the processing method of the particle fuel. The processing method comprises the steps of preparing the flame accelerator, the anti-slagging agent and the sulfur fixing agent according to selected parts by weight; mixing and smashing; drying: drying an obtained wood pellet mixture at high temperature; extrusion forming: sending the dried solid fuel into a granulator to be extruded and granulated and finally cooling to obtain the environment-friendly biomass particle fuel. The environment-friendly biomass particle fuel and the processing method disclosed by the invention have reliable performance, and the environment-friendly biomass particle fuel can meet the requirement of energy conservation and environmental friendliness and meanwhile has long combustion time and high combustion ratio.

Description

technical field [0001] The patent of the invention relates to the technical field of biomass fuel, in particular to an environment-friendly biomass particle fuel and a processing method. Background technique [0002] The rapid economic development is inseparable from energy, and the shortage of traditional fossil energy oil, natural gas and coal is becoming more and more serious. Biomass energy, as the fourth largest energy source, has become an energy source with great development potential among new energy sources due to its renewable and zero-carbon emission characteristics. Biomass pellet fuel, also known as Biomass MouldingFuel (BMF for short), uses agricultural and forestry wastes as raw materials, and after crushing and drying processes, it is made into various shapes (such as granular) and can be directly burned. A new type of clean fuel. The existing pellet fuel still has the following disadvantages: because the raw materials are all crops, the content of alkali m...
