thermal power 750,000 kcal biomass pellet hot air furnace is an efficient and environmentally friendly heat energy conversion equipment. Its core is to convert biomass pellet fuel into hot air for various industrial or agricultural applications. Its working principle combines the efficient utilization of biomass energy with the essence of modern combustion technology. The following is a detailed explanation of its working principle.The biomass pellet hot air furnace first feeds the compressed biomass pellet fuel into the combustion chamber through a feeding device. These biomass pellets usually come from wood, crop straw or other biomass waste. They not only have high calorific value, but also have no sulfur emissions during combustion, and are highly environmentally friendly.In the combustion chamber, the biomass pellet fuel is ignited by the burner and fully burned under specific combustion conditions. In this process, the combustible substances in the fuel undergo a violent oxidation reaction with oxygen, releasing a large amount of heat energy. Advanced combustion technology and structure are incorporated into the design of the hot blast furnace, such as the auxiliary combustion chamber, which allows unburned carbon particles and combustible gases to continue to burn in an environment with sufficient oxygen, thereby improving the combustion efficiency of the fuel and reducing the emission of black smoke and harmful gases caused by incomplete combustion.The high-temperature flue gas produced by the combustion then enters the heat exchanger system. This is a key component in the hot blast furnace, which is responsible for transferring the heat in the flue gas to the air. The hot blast furnace is usually equipped with a water-cooled wall or a metal heat exchanger. During the flow of the hot blast furnace, the high-temperature flue gas transfers its heat to the air flowing through the heat exchanger by conduction and convection. In this process, the air is heated to become high-quality hot air.The hot blast furnace is equipped with an intelligent control system, such as a PIC programmable controller, which can accurately control the combustion intensity, hot air temperature and flow rate. This system ensures the stable operation of the entire hot blast furnace and optimizes the thermal efficiency. By adjusting the control system, the hot blast furnace can output hot air of different temperatures and flows according to actual needs to meet the needs of various application scenarios.During the operation of the hot blast furnace, flue gas treatment also needs to be considered. The flue gas after the heat exchanger still contains certain pollutants, such as particulate matter, sulfur dioxide, etc. In order to meet the emission standards, the hot air furnace is usually equipped with dust removal and desulfurization equipment to further treat the flue gas. This not only helps to reduce environmental pollution, but also improves the environmental performance of the hot air furnace.In summary, the thermal power 750,000 kcal biomass pellet hot air furnace converts biomass pellet fuel into high-quality hot air through efficient combustion technology and advanced heat exchanger design. Its intelligent control system ensures the stable operation of the system and the optimization of thermal efficiency, while the flue gas treatment equipment further improves the environmental performance of the hot air furnace. This equipment has broad application prospects in many fields, such as agricultural drying, industrial production, etc.
