U Bends Water Heat Boiler Economizer Continuous Modulating

Feb 24, 2012 · Boiler economizer is a device that uses a portion this remained energy of the flue gas to heat up inlet water (feed water) to the boiler. Since the heat energy is given to the water before it gets fed to the boiler, the requirement of fuel for producing steam is optimized. Because of that, we call this device as an economizer.

Working principle of Economizer - BrainKart

Requirement for various boiler types - water tube boilers and more; The watertube boiler is employed for high-pressure, high-temperature, high-capacity steam applications, e.g. providing steam for main propulsion turbines or cargo pump turbines. Firetube boilers are used for auxiliary purposes to provide smaller quantities of low-pressure steam

The Boiler Efficiency Calculator allows you to calculate the energy efficiency benefits of adding one type of economizer to a boiler system. Economizers are heat exchangers that transfer the heat in the flue gas to another medium‚ generally the boiler feed-water‚ although other …

Economizers | CleanBoiler.org

Economisers. The flue gases, having passed through the main boiler and the superheater, will still be hot. The energy in these flue gases can be used to improve the thermal efficiency of the boiler. To achieve this the flue gases are passed through an economiser. The economiser is a heat exchanger through which the feedwater is pumped.

Draft fan—a fan used to control draft in a boiler, p. 297. Economizer—the section of a boiler used to preheat feedwater before it enters the main boiler system, p. 293. Filtration—the process of removing particles from water or some other fluid by passing it through porous media, p. 301.

Power plant maintenance: Economiser and its types

Economizers designed for natural gas only, would likely plug-up if installed on a coal boiler and would face increased risk of corrosion if installed on an oil-fired boiler. Some units are designed to keep the flue gases above condensation temperature, and others are made of materials that resist the corrosive effect of condensed flue gases.

What are the types of economisers, and which one of them

Economizers are heat exchangers that transfer the heat in the flue gas to another medium‚ generally the boiler feed-water‚ although other streams are sometimes used such as make-up water. There are 2 types of economizers: non-condensing and condensing. Non-condensing economizers. The most common are non-condensing economizers. They are heat exchanger coils‚ usually finned‚ that are located in the flue …

BOILER ECONOMISER - Thermal Power Tech

Economizers for Any Application. The E-Tech economizer is essentially a finned tube heat exchanger installed in the boiler flue exhaust stack. Hot flue gases pass over the finned tubes as boiler feedwater circulates inside the tubes. This preheats the feedwater, recovering otherwise wasted heat from the escaping flue gas. The higher temperature
