Embodiment 1

[0059] The production process of biomass fuel comprises the following steps:

[0060] (1) select poplar sawdust as raw material;

[0061] (2) drying poplar wood chips in a blast drying oven at 105°C until the moisture content of poplar wood chips is 10wt%;

[0062] (3) Compress the dried poplar wood chips into granules with a diameter of 8 mm through a granulator, and cool to room temperature to obtain biomass fuel.

Embodiment 2

[0064] The production process of biomass fuel comprises the following steps:

[0065] (1) select poplar sawdust as raw material;

[0066] (2) drying poplar wood chips in a blast drying oven at 105°C until the moisture content of poplar wood chips is 10wt%;

[0067] (3) The dried poplar sawdust is subjected to steam explosion treatment, the steam pressure is 1.2MPa, and the pressure is maintained at 210°C for 3 minutes, and the pressure is released instantly to obtain the steam explosion material; the steam explosion material is then compressed into granules by a granulator, The particle diameter is 8 mm, and after cooling to room temperature, biomass fuel is obtained.

Embodiment 3

[0069] The production process of biomass fuel comprises the following steps:

[0070] (1) select poplar sawdust as raw material;

[0071] (2) drying poplar wood chips in a blast drying oven at 105°C until the moisture content of poplar wood chips is 10wt%;

[0072] (3) The dried poplar sawdust was subjected to microwave treatment, the microwave treatment time was 3 minutes, the temperature was 50°C, and the microwave power was 600W; the microwave-treated poplar sawdust was compressed into particles by a pellet machine, and the particle diameter was 8mm, after cooling to room temperature, biomass fuel was obtained.

Abstract

The invention discloses biomass fuel and a production process thereof. The production process includes following steps: (1), selecting materials; (2), smashing; (3), drying; (4), extrusion forming. By studying heat release amount of the raw materials, factors having influence on burning rate and production process and analyzing burning dynamic characteristics of the formed biomass fuel, the fuel is simple in composition, reasonable in compatibility, low in cost, high in burning rate and low in slagging rate. The production process is safe, simple and convenient, burning performance of the biomass fuel can be improved effectively, running efficiency of a biomass boiler is improved, and utilization effect of the biomass fuel is promoted greatly.

Description

technical field [0001] The invention relates to the technical field of biomass fuel, in particular to a biomass fuel and a production process thereof. Background technique [0002] With the development of the world economy, the rapid increase of population and the continuous improvement of people's living standards, the world's energy demand continues to increase, resulting in a rapid increase in oil prices, and insufficient energy supply has become a bottleneck restricting the country's economic development. Energy is one of the key factors influencing the process of sustainable development. At present, my country is facing the constraints of conventional energy resources, excessive reliance on coal resources, serious pollution and low energy utilization efficiency in the use of energy. [0003] In order to reduce the impact on the environment caused by the use of fossil energy in our country and reduce our dependence on fossil energy, it is necessary to change the way of ...
