Problems solved by technology

[0003] Invention patent (CN101550374B) discloses a biomass solid molding fuel additive, using Al 2 o 3 , Fe 2 o 3 The mixture of kaolin and kaolin is used as an additive, which is uniformly mixed by a general method. The additive is mixed into the straw at a weight ratio of 3% to 8%. Although the invention has achieved the effects of increasing the ash melting point and reducing ash accumulation and slagging, The additives used are resource-based minerals or chemicals, resulting in high additive costs, and it is difficult to achieve uniformity of additive components by mechanical mixing

Abstract

The invention discloses biomass granular fuel with high adhesion. The biomass granular fuel is prepared from the following raw materials in parts by weight: 60-65 parts of corn straw, 55-60 parts of rice straw, 15-20 parts of waste paper pulp, 5-7 parts of magnesium oxide, 4-6 parts of sodium hydroxide, 2-4 parts of sodium chloride, 3-5 parts of potassium chlorate, 4-6 parts of manganese dioxide and 5-10 parts of lime milk or calcium carbide slag. The invention also discloses a preparation method of the biomass granular fuel with high adhesion. The biomass granular fuel with high adhesion adopts a composite binder prepared from the waste paper pulp and the magnesium oxide, so that the mechanical strength of the biomass granular fuel is improved; the composite binder plays an important rolein the production, transportation and storage of the biomass granular fuel; the wear of material granules on molding equipment is reduced, the fuel processing performance is improved, and the equipment power loss is reduced; the produced biomass granular fuel is good in adhesion, high in combustion value, low in combustion pollution and beneficial to the construction of an ecological environment.

Description

technical field [0001] The invention relates to the field of biomass pellet fuel preparation, in particular to a biomass pellet fuel with high cohesiveness. 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. CO released during combustion of biomass pellet fuel 2 Roughly equivalent to the CO absorbed by photosynthesis during its growth 2 , so the greenhouse gas CO of biomass particles 2 For zero emissions. Biomass fuel is a renewable energy source. As long as there is sunlight, the photosynthesis of green plants will not stop, the biomass energy will not...
