Product Description

A335 P9 / SA 335 P22 ASTM Standard Power Plant Economizer 6 Inches Diameter Sprial Welding

Introduction

• Boiler economizers are heat exchange devices with finned tubes that heat a liquid, sometimes water, up to however sometimes doesn't exceed the boiling purpose of liquid.

• We can manufacture three types of boiler economizer, bare tube economizer, H finned tube economizer and spiral finned tube economizer.

• H-finned tube economizer is high efficient heat exchanger economizer which is consisted of H-finned tubes.

• Compared with bare tube economizer, H-finned tube economizer can enlarge the heat exchange area and reduce the number of tubes.

• It also can increase the flue gas flow area in order to reduce the flue gas flow speed and abrasion.
H-finned tube can be made as double H finned tubes , with high rigidness to fit long tube row.

• The spiral finned economizer is a newly designed heat transfer equipment, consists of spiral fin tubes to overcome the serious abrasion and short service time.
