Air 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

Air preheater tubes are made from Cold Drawing process and are generally of Carbon Steel material. The application of these tubes is in an area where the tubes is not subjected to extremely high temperatures and pressures. Hence, the use of Carbon Steel tubes in applications for Air Preheater Tubes is generally preferable. There are various types of Air Preheaters; one of them widely used is Tubular Type Air Preheater. In this type of Air Preheater, straight tube bundles are used, which pass through the outlet ducting of the boiler and open at each end outside of the ducting, The hot furnace gases pass around the air preheater tubes, transferring heat from the exhaust gas to the air inside the preheater. Ambient air is forced by a fan through ducting at one end of the air preheater tubes and at other end the heated air from inside of the tubes emerges into another set of ducting, which carries it to the boiler furnace for combustion.
