Low Nitrogen Combustion System

The biomass pyrolysis gas burner in the carbonization system is a dual-fuel flue gas recirculation low-ammonia burner. It can burn biomass pyrolysis gas, diesel or natural gas and so on. In terms of controlling nitrogen oxides, the structure of the burner is reasonably designed to reduce the amount of nitrogen oxides generated during combustion, and then the return flue gas is used to reduce the oxygen partial pressure of the combustion air and reduce the flame center temperature, so as to reduce the emission concentration of nitrogen oxides.

Equipment Features:

1.Pyrolysis gas and combustion air are distributed in stages to avoid flame concentration and inhibit the generation of nitrogen oxides.
2.The oxygen partial pressure of the combustion air is reduced by using the return flue gas, reduce the flame center temperature, thereby inhibiting the concentration of nitrogen oxides.

Heat Absorption Heat Exchanger

It is mainly composed of four parts: generator, condenser, evaporator and absorber The basic working principle is as follows:

The use of working heat sources (such as water vapor, hot water and gas, etc.) in the generator to heat the dilute solution transported by the solution pump from the absorber, and the water in the solution evaporates out.

Water vapor enters the condenser and is condensed into refrigerant water by the cooling medium.

The refrigerant water is throttled into the evaporator, absorbing the heat of the refrigerant water and intensifying into water vapor.

In the generator after the process of remaining concentrated solution into the absorber, mixed with water vapor from the evaporator, absorb water vapor and return to the original concentration, into a dilute solution. The dilute solution passes through the solution pump and then enters the generator for continued circulation.
