● Economizer is a heat exchanger that can increase the water temperature to 50 centigrade by using on external chimney boiler and totally, such a 10 centigrade increasing in sustenance water temperature can lead to increase 2 percent higher efficiency. As the result, will be included decreasing costs, fuel consuming and air pollution.
● The substance of the Economizers in the boiler with lower capacities is Carbon Steel (17MN4) and in higher capacities is Stainless steel.
● The work pressure of the Economizer is designed and manufactured based on the boiler performance pressure.
