Boiler Economizer Customizable Dimensions Steel Material Heat Exchange Part What materials are used for economizer tubes? Carbon steel (SA178, SA192) for low/medium pressure, alloy steel
for high pressure. Introduction Installed in the lower part of a boiler’s tail flue, an economizer
recovers waste heat from flue gas. It heats boiler feed water up to
the steam drum’s saturated pressure—acting as a heating surface. By
using high-temperature flue gas heat, it cuts exhaust temps, saves
energy, and boosts efficiency—hence the name. Steel tube economizers work across all pressures, even as boiling
types. They typically use 32–51mm carbon steel tubes, sometimes
with fins to enhance heat transfer. These economizers are made of
parallel, horizontally arranged elbow pipes (often called
serpentine tubes).
Specifications
Function 1.The economizer is a steam generation system as like a boiler. when the exhaust gas discharge from the engine cylinder through the exhaust valve it goes to the boiler for generate steam by heating of water. 2.After those gas it goes through the economizer the remaining exhaust gas temperature is heated the water in economiser. it help to generate steam, and it is improving the efficiency and save the fuel consumption 3. An economizer uses the waste heat from the boiler exhaust, that would otherwise be lost to atmosphere to (in most cases) preheat the feed water into the boiler.This improves the boiler efficiency and reduces fuel costs.
Technical specifications Material Structure
Advantages 1. Absorb the heat of low-temperature flue gas, reduce the smoke discharge temperature, reduce smoke loss, and save fuel. 2. Since the feed water is heated in the economizer before entering the steam drum, the heat absorption of the feed water on the heating surface is reduced, and the economizer can be used to replace part of the evaporation heating surface with higher cost. 3, feed water temperature increased, into the drum will reduce the wall temperature difference, thermal stress corresponding to reduce, extend the service life of the drum.
