Postcombustion plant heat recovery type
They treat polluted air with solvents or organic substances at low temperatures. The air is first preheated to a temperature of about 350 ° C and introduced into the post-combustion chamber by duct burner that will use part of the air for burning the fuel (normally natural gas or LPG).
The temperature in the post-combustion chamber is automatically regulated between 750 and 850°C, the residence time can vary from 1 to 2 seconds.
Air flow to be treated: between 1000 and 6000 mc / h
Solvent concentrations: depending on the type up to 10gr / mc
There is the possibility of recovering heat, to produce hot air or hot water, by inserting a heat exchanger downstream of the preheater.
