Contact SupplierAir preheater are heat exchanger to preheat or air heating of the combustion air by means of flue gas, steam, water or thermal oil. Air preheaters are used when exhaust temperatures of combustion systems are particularly high. This extracts the hot exhaust valuable energy, which discharged otherwise unused into the atmosphere and warming means of this exhaust heat the combustion air of the combustion process.
GANESHA air preheater can be retrofitted easily behind all boiler makes and sizes.
Functionality
Air preheater are liquid and air heat exchanger or exhaust and air heat exchangers. They are designed and carried out individually depending on the application. Air preheater can be performed in counterflow, co-current flow, co-current flow-countercurrent or cross-countercurrent or cross-co-current flow. The design depends on the media and the temperature conditions. For small construction, finned tubes are suited to arrange in a small space much heating surface. Is in the exhaust gas or in the air containing dust or other particles, so that deposits are expected, preferably smooth tubes are used, which are less prone to deposits and will be clean easier.
In most cases, an air preheater is performed in several stages, that means, it consists of several individual heat exchangers connected in series on the air side.
At steam boiler plants, the first stage often is a water or condensate heat exchanger, a steam-operated low-pressure heat exchanger connects in the seco
