GAS HEATER - EG
In gas heater with indirect heating, the ?owing air does not come into contact with a ?ame.
The air is heated using convection during the ?ow between the furnace tubes containing ?owing
hot gases which are the product of combustion. The exchanger consists of a combustion
chamber and an exchanger equipped with a system of tubes. The combustion gas is directed
through these tubes into the chimney. Gas heaters can operate periodically with burner turning
off, or in a continuous mode at power load of the burner. If the burner operates periodically
- when the combustion chamber is cooled - stream condensation takes place.
