Abstract

The invention discloses biomass granular fuel with a low sulfur number and a high combustion rate. The biomass granular fuel is prepared from the following raw materials in parts by weight: 18 to 24 parts of bamboo sawdust, 10 to 30 parts of pine sawdust, 35 to 45 parts of castor stalk, 40 to 50 parts of larch sawdust, 10 to 15 parts of elm sawdust, 10 to 15 parts of willow sawdust, 10 to 15 parts of aspen sawdust, 5 to 10 parts of sulfur-fixing agent, 7 to 11 parts of coupling agent, 15 to 17 parts of diatom ooze, 4 to 6 parts of magnesium metal powder and 8 to 14 parts of bonding agent. Compared with the prior art, the biomass granular fuel is simple in process, and is easy and convenient to operate; the bamboo sawdust and the pine sawdust are carbonized and modified, so that the toughness and density of inorganic carbon particles are improved, the combustion heat values of the bamboo sawdust and pine sawdust residual carbon are increased, volatile components in a combustion process are reduced, and the sulfur content of discharged waste gas is low.

Description

technical field [0001] The invention relates to the field of biomass pellet fuel preparation, in particular to a biomass pellet fuel with low sulfur value and high combustion rate and a preparation method thereof. Background technique [0002] With the increasing demand for energy, the widely used non-renewable energy such as oil, coal, and natural gas is facing the problem of depletion. In order to solve the energy crisis that mankind is about to face, it is necessary to develop renewable new energy sources to replace non-renewable fossil fuels. Biomass energy, as a cheap and clean renewable energy, is attracting more and more attention from people. As a large agricultural country, our country has comparative advantages in raw material supply, energy demand and government policy support of biomass energy. big advantage. The source of sawdust and straw is abundant, the cost is low, and the sulfur content of sawdust is very low. The biomass pellet fuel prepared from it as a...
