Shangyou County uses sawdust pellet combustion machine

The biological particles selected for biomass combustion machines are single pure wood particles. Normally, pure wood particles are not prone to coking. If coking occurs, the raw materials must have been mixed with some substances by the supplier during procurement Due to my previous experience in running a pellet factory and our own production of material incinerators, the use of biofuels in our own incinerators must not cause coking. However, the pellets I produce still cause coking, which I am puzzled by. Later, when entering the raw materials, I inspected each truck of wood shavings and found that some of them had been sanded Another biofuel plant also discovered this phenomenon So don't think that just because you haven't participated in something, you must not have participated. Sometimes it's someone else who has participated that you may not know Secondly, the raw materials for the selected biological particles cannot all be based on trees. Generally, the better materials on the market now are miscellaneous wood, such as wood, pine wood, and rosewood. If they can withstand it, rosewood can be used. Pure rosewood particles have a higher calorific value than other particles and do not coke, of course, this refers to particles made without other raw materials

Biomass pellet combustion equipment belongs to the category of biomass energy-saving stoves. The stove is designed with a comprehensive ventilation and oxygen supply system that ensures full combustion. It also utilizes secondary oxygen supply technology, adds secondary air technology and air path channels, and uses the oxygen deficient effect to heat the reaction conversion process to produce gasification, which causes biomass fuel to undergo oxidation reaction after high-temperature cracking, generating some combustible gases (carbon monoxide, hydrogen, methane, etc.). Under the action of secondary oxygen supply, jet combustion occurs, improving the utilization efficiency and combustion efficiency of the fuel, thereby achieving energy-saving and environmental protection effects, while significantly reducing the emission of harmful pollutants such as carbon dioxide and sulfur dioxide. This technology extends the swirling distance and time of high-temperature flue gas flow in the furnace by setting insulation layers and adding fire blocking rings, thereby reducing heat loss and improving thermal efficiency. It saves fuel and time, and is safe, hygienic, and easy to use.
From the perspective of thermodynamic principles, biomass pellet fuel stoves have basically met three conditions:
One is the ability to fully burn fuel, converting the chemical energy in the fuel into heat energy more efficiently;
Secondly, it has good heat transfer and insulation effects, which increases the effective utilization of heat value and reduces the heat dissipation heat value;
Thirdly, waste heat can be effectively utilized to minimize exhaust heat and other heat losses. At the same time, solid fuels can be used under high temperature and oxygen deficient conditions, while controlling the excess air supply coefficient reasonably
