Combustion Air Heater Economizer

Combustion Air Heater Economizer

The flue gas discharged from the chimneys of industrial boilers or processes has a large amount of thermal energy. By using this energy in the flue gas in economizers, energy saving is achieved by increasing the burner combustion air temperature.

By using the energy in the flue gas discharged from the chimneys of industrial boilers, the temperature of the burner combustion air can be increased. Thus, they save energy.

Depending on the boiler flue gas outlet temperature, the status of the current boiler and the type of fuel, an increase in efficiency between 1,5% and 3% is achieved in the boiler or plant efficiency. Depending on the increase in efficiency, less fuel is consumed for the same capacity or more heat is produced for the same amount of fuel consumption.

Less CO2 will be released to nature with less fuel burned. Therefore, CO2 emissions will also be minimized.

  • Efficiency increase by supplying warmer air to the burner air fan
  • High efficiency with the most optimum flue gas output possible
  • Specially designed system for easy and fast installation
  • Compact thanks to optimally designed pipe and pipe layout design
  • Increasing efficiency thanks to additional economizers
  • PLC and Touch Screen clearly displaying boiler control operating data
  • Easy connection to the system thanks to flue gas and air inlet connections
  • Durable, reliable and long-lasting thanks to the manufacturing stages mandated by the standards

The economizer mounted behind the boiler is designed to increase the efficiency of the system to heat the burner combustion air with the flue gas discharged from the boiler. The economizer is manufactured from finned tubes and the system efficiency is maximized with much smaller heat transfer surfaces.

The fin is welded to the tubes by high frequency welding method. Thus, a complete heat transmission is provided between the fin and the tube and the heat transfer is perfect. The finned tube is subjected to tensile and bending tests in the laboratory of the company and is tested to obtain the required strength in hot/cold and stop/start operating conditions throughout the life of the economizer.

The economizer tube distribution is designed as full cross flow so that the air and flue gas flow homogeneously through the economizer.

The economizer has the necessary safety, temperature and pressure gauges and 1 man-entry cover.
