Problems solved by technology

However, pellet fuel made from a single plant often has a low ignition point, high ash content, and the smoke produced is very polluting to the environment, and even if high-cost screening treatment is adopted, it cannot achieve full combustion, and the utilization rate is low
In addition, when producing pellet fuel in rural areas, a variety of different crop wastes are often mixed together for preparation. Due to the unreasonable formula, it is actually difficult to achieve a good combustion effect for the fuel obtained.

Embodiment 1

[0026] The steps for preparing biomass pellet fuel in this embodiment are as follows:

[0027] (1) Drying: the straw, branch leaves, larch wood waste, mahogany waste and elm waste are dried naturally.

[0028] (2) Pulverization: the dried straw, branch leaves, larch wood waste, mahogany waste, and elm wood waste are respectively pulverized to obtain straw powder, branch leaf powder, larch wood chips, mahogany wood chips, and elm wood chips.

[0029] (3) Screening: the crushed straw powder, branch leaf powder, larch wood chips, mahogany wood chips, and elm wood chips were respectively screened with a 40-mesh screen.

[0030] (4) Ingredients: Mix 50 parts of sieved straw powder, 45 parts of branch leaf powder, 26 parts of larch wood chips, 12 parts of redwood saw chips, and 30 parts of elm wood chips, and add 9 parts of calcium carbonate and 8 parts of waste oil and 5 parts of bentonite are uniformly mixed with a mixer to obtain a mixture with a water content of 10-20%.

Abstract

The invention relates to biomass granular fuel, which is prepared from the following raw materials in parts by weight: 40 to 50 parts of stalk powder, 40 to 50 parts of branch leaf powder, 20 to 30 parts of dahurian larch wood dust, 10 to 20 parts of redwood dust, 20 to 30 parts of hardwood dust, 8 to 15 parts of sulphur-fixing agents, 5 to 10 parts of lubricating agents and 4 to 8 parts of loosening agents. The invention also relates to a preparation method of the biomass granular fuel. The biomass granular fuel provided by the invention has the advantages of high calorific value, high combustion utilization rate and small environment pollution; the development of new energy resources can be promoted; the fuel can be used for providing life and production energy for rural areas.

Description

technical field [0001] The invention relates to the technical field of new energy fuels, in particular to a biomass particle fuel and a preparation method thereof. Background technique [0002] With the continuous development of the global economy, human demand for energy continues to increase, and the total amount of non-renewable energy such as oil, natural gas, and coal continues to decrease. Therefore, the development of renewable energy has attracted the attention of people all over the world, especially for developing countries. It means a lot. [0003] Biomass energy is a kind of renewable energy. It is the energy form of solar energy stored in biomass in the form of chemical energy. Conventional solid, liquid and gaseous fuels are inexhaustible and inexhaustible. Biomass pellet fuel is a typical biomass solid shaped fuel, which has the advantages of high efficiency, cleanliness, easy ignition, and zero emission of carbon monoxide. industrial field.
