  • Power Station Boiler | Sagging Economizer Tubes

    However, it is known that economizers fitted to water tube boilers are potentially vulnerable to overheating at startup. In normal operation the heat in the combustion flue gases is still recovered by the economizer heating surface but at start-up the feedwater flow is relatively stagnated because the boiler is not producing steam, and Learn More

  • Boiler Economiser : Definition, Function & Types of

    This type of economizer is typically feasible for boilers of at least 590 kW (60 hp) and where at least 60 percent of the recov- erable waste stack heat can be used to preheat cold water. The boiler must also have a forced-draft burner and must not beLearn More

  • Maximize Boiler Heat Recovery with Condensing Economizers

    An economizer is a heat exchanger that is used to transfer energy from an air stream into a liquid stream. Most typical economizers use the flue gas exiting the boiler to preheat boiler feedwater being delivered to the boiler. Most natural gas or fuel oil fired boilers will utilize economizers with extended surface finned tubes.Learn More

  • BOILER ECONOMISER - Thermal Power Tech

    In boilers, economizers are heat exchange devices that heat fluids, usually water, up to but not normally beyond the boiling point of that fluid.Economizers are so named because they can make use of the enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler, thereby recovering more useful enthalpy and improving the boiler's efficiency.Learn More
