Low-temp Economizer in Power Plant Bolier

Typical Unit Capacity: 660MW Power Unit

Project Type: EPC

Installation Site: Changshu, Jiangsu Province

Project Overview: The low temperature economizer is set between the APH outlet and EP inlet, reducing flue gas temperature from 120~150C to 90~100C and then entering EP, which enhance the dust collection efficiency, reduce desulphurization water consumption and save coal around 2 ~3g/kWh. So the power unit efficiency can increase by 0.5~1.2%. The waste heat can be used for preheating condensation water, heating water or daily application. Normally, the heat pipe, fin pipe such as H type or spiral type, and flexible coating are designed for low-temp. economizer subject to different working conditions.
