Burner is a system that uses biomass as fuel and generates heat energy through efficient combustion technology for drying various agricultural products and biomass fuels. This equipment adopts boiling semi gasification combustion and tangential swirl air distribution design, which enables complete combustion of fuel with a combustion efficiency of over 90%.
The working principle of a burner is to use fuel and air to react and convert chemical energy into thermal energy. Before entering the combustion chamber, fuel and air are first mixed in the combustion head. During the mixing process, the ratio of fuel and air is controlled to achieve the optimal ratio of the mixed gas, thereby ensuring full, stable, and efficient combustion of the fuel. The combustion of fuel and air produces high-temperature and high-pressure gas, which is discharged through the outlet of the combustion engine and completes the process of thermal energy conversion.
It mainly consists of the following parts:
1. Air intake system
The intake system of the burner introduces external air into the burner through pipes and thoroughly mixes fuel and air. The intake system mainly consists of an inner pipe, an outer pipe, an air guide plate, a regulator, a nozzle, etc.
2. Combustion chamber
A combustion chamber is a place where high-temperature and high-pressure gases are produced through the chemical reaction between fuel and air. The combustion chamber is divided into two types: direct combustion and indirect combustion. A direct combustion chamber burns directly after mixing fuel and air, producing high-temperature and high-pressure gas directly. Indirect combustion chambers first oxidize the fuel nearby, then mix it with air and burn it, producing high-temperature and high-pressure gas.
3. Combustion head
The combustion head is a place where fuel and air mix. After the fuel comes out of the nozzle, it mixes with the air entering the combustion head to form combustible gas, which is ignited by the igniter and produces high-temperature and high-pressure gas in the combustion chamber.
4. Control system
The control system of the burner includes ignition control, temperature control, and pressure control. Through the control system, the burner can maintain a stable combustion state, ensure the quality of the outlet gas, and also achieve high efficiency and energy conservation.
