Product Introdution
Economizer is a device installed at the lower part of the tail flue of a boiler to recover the waste heat from the exhaust gas. It heats the boiler feedwater into a saturated water heating surface under the pressure of the steam drum. Due to its absorption of heat from high-temperature flue gas, it reduces the exhaust temperature of the flue gas, saves energy, and improves efficiency. Therefore, it is called an economizer.
The steel tube economizer is not limited by pressure and can be used as a boiling type. It is generally made of carbon steel pipes with an outer diameter of 32-51 millimeters. Sometimes fins and ribs are added to the tube to improve heat transfer efficiency. The steel tube economizer consists of horizontally arranged parallel elbow pipes (commonly known as serpentine pipes).
Economizers are mainly suitable for industry and are gradually becoming popular in agriculture and some related industries.

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).
