Catalytic air heater

схема вгск анг2.jpg

Provides economic and ecologically friendly fuel combustion, low metal consumption, reliable operation.
Heating of greenhouses, warehouses, working and service areas.

The operation is based on two-stage combustion of liquid or gaseous (natural gas) fuel.
The first stage is fuel flaring.
The produced fuel gas is mixed with air using a centrifugal vent to reach the required temperature and fed to the second chamber bearing a honeycomb monolith catalyst. At 400–800°C, the catalytic cartridge provides the full oxidation of carbon monoxide and products of fuel incomplete burning, as well as reduction of nitrogen oxides.
