Product Introdution
Economizer tube is an important part of boiler, which is mainly made of seamless steel tube by bending or folding.
Cast iron economizer consists of a series of horizontal cast iron pipes connected to each other with cast iron elbows and flanged ends.
The tubular economizer consists of a series of parallel serpentine tubes, which are made of seamless steel pipes with an outer diameter of 25 ~ 42 mm, and the pipes are usually arranged in a staggered arrangement.
Working Process of Boiler Economizer
There are three stages from the feed water in the boiler heated into superheated steam:feed water preheating, evaporation, and superheating. The three stages are finished on three different heating surfaces. The boiler steam and water circuit are composed of the three different heating surfaces as well as their connecting pipes. Boiler economizers are one of them, and it is right the equipment to preheat the feed water. Thus, it is the heating surface with the lowest temperature for boiler working fluid in the boiler steam and water circuit. The working fluid passing through this equipment is monophasic water(non-boiling economizer).
