Problems solved by technology

[0003] Although biomass pellet fuel has many advantages, ordinary biomass pellet fuel contains high alkali metal elements such as Al, Ca, Fe, K, Mg, etc., which makes it easy to slagging, easy to accumulate dust, and difficult to burn during combustion. Sufficient, resulting in low combustion efficiency and low heat energy value, and biomass pellet fuel is easy to be damp, which affects its combustion quality

Abstract

The invention discloses a biomass particle fuel with a high calorific value and a preparation method. The biomass particle fuel comprises the following components in parts by weight: 30 to 50 parts ofsawdust powder, 20 to 40 parts of straw, 20 to 40 parts of rice husk, 5 to 10 parts of organic solid waste, 1 to 5 parts of bentonite, 5 to 20 parts of pulverized coal, 0.1 to 1 part of an oxygenate,2 to 5 parts of a combustion improver, 2 to 7 parts of a sulfur fixing agent and 1 to 5 parts of a moistureproof agent. According to the biomass particle fuel with the high calorific value provided by the invention, when the biomass particle fuel is actually used, biomass energy and organic solid waste are organically combined for use, the produced biomass particle fuel is high in caking ability,high in calorific value, high in combustion efficiency and less in combustion pollution and facilitates the construction of a biological environment, some pulverized coal is appropriately added, thecombustion effect can be strengthened, the calorific value of combustion can be improved, and the moistureproof agent is added inside the fuel, the storage of the fuel can be facilitated, the fuel isavoided from being affected by damp and moisture, and then the combustion quality of the fuel is improved, and simultaneously, the problem that the calorific value of combustion is low caused by the fact that the fuel is affected by damp is avoided.

Description

technical field [0001] The invention relates to the technical field of biomass particle fuel, in particular to a high calorific value biomass particle fuel and a preparation method thereof. Background technique [0002] Using wood chips, bamboo chips, branches, straw, plant shells, etc. as raw materials, through professional machinery, special technology, without any chemical additives, the granular fuel formed by high-pressure and low-temperature compression is collectively called biomass pellet fuel. Biomass pellet fuel has high calorific value and is clean and pollution-free. It is a high-tech environmental protection product that replaces fossil energy. The CO2 released by biomass pellet fuel during combustion is roughly equivalent to the CO2 absorbed by photosynthesis during its growth, so the greenhouse gas CO2 emission of biomass pellets is zero. Biomass fuel is a renewable energy source. As long as there is sunlight, the photosynthesis of green plants will not stop...
