waste heat thermal oil boiler auxiliary accessory boiler air preheater
The air preheater is a heat exchanger that uses the flue gas heat from the rear of the boiler to heat the air needed for combustion.The tube and tube plate can be sealed with heat resistant packing, and can be sealed by welding.Customers can choose according to their own needs.
In the classical use, air preheaters are connected behind high-pressure steam boilers or thermal oil boilers with a flue gas temperature up to 400 ° C. Their exhaust temperatures lend themselves to preheat the combustion air up to 300 ° C. In this way, an air preheater save up to 10% of fuel costs and thus enables payback periods of less than two years. Meanwhile, air preheater also be used in low temperature ranges in order to make the most efficient use of the fuels and counter the rising fuel prices.
Advantages of the Air Heater
Small design and minimal loss of radiation through high heating surface concentration
Self-supporting structure on a base frame allows free expansion in all dimensions
Bearing additional load of up to 10% of its own weight without additional steel structure is possible
No moving parts, i.e. no additional energy requirement and no maintenance costs
Short assembly times through workshop assembly into pre-mounted modules
