Design of Finned-tube Economizer of E-670-13.8 Boiler and Its Performance in Zhangze Power Plant

Zhimin Liu

Abstract

The boilers of Unit 3 in Zhangze Power Plant are E-670-13.8-545KT (TE-215/AC series) steam boilers manufactured by tower do Rogge Boiler-making Plant of former Soviet Union. Because of the high coal ash content, the erosion of economizers is quite serious. To use economizer s retrofitting plan with finned-tube economizer can reduce erosion and improve the economizer life. The retrofitting project was implemented in 2004 and obtained good effect.
