2019-5-27 · economizer in boiler. Economizer can be provided to utilize the flue gas heat for pre-heating the boiler feed water. On the other hand, in an air pre-heater, the waste heat is used to heat combustion air. In both the cases, there is a corresponding reduction in the fuel requirements of the boiler. A simple sketch of an economizer is shown in

Importance & Use of Economiser in Thermal Power

It is used in all modern plants. The use of economizer results in saving fuel consumption, increases steaming rate and boiler efficiency. Some of the common applications of economizer are given below, In steam power plants it captures the waste heat from boiler stack gases (flue gases) and transfers it to the boiler feed water. Air-side

Economizer in Thermal Power Plant | Economizer -

What is an Economizer? An economizer is a mechanical device which is used as a heat exchanger by preheating a fluid to reduce energy consumption. In a steam boiler, it is a heat ex-changer device that heats up fluids or recovers residual heat from the combustion product i.e. flue gases in thermal power plant before being released through the

EPCB High Efficiency Steam Boiler Economizer - China

Description. Fine tube economizer introduction: Fine tube economizer is specially designed for fuel gas steam or hot water boiler. Economizer installed behind the boiler exhaust port, heat the feeding water of the boiler through the waste heat of fuel gas to reduce the exhaust smoke temperature and improving the thermal efficiency of the boiler.The economizer can not only greatly reduce fuel

Environmental Protection Boiler Economiser For

They are a device fitted to a boiler which saves energy by using the exhaust gases from the boiler to preheat the cold water used to fill it (the feed water). When you purchase a thermal fluid heater, the cost of fuel to operate the heater is a major concern. The amount of fuel needed is related to the thermal efficiency of the heater.

Saving Boiler Fuel - Veolia

2015-11-3 · An economizer allows some of this otherwise lost energy to be recovered by using a heat exchanger located on the stack to heat boiler feedwater. For every 40 q to 50 qF drop in stack temperature, a 1% gain in boiler efficiency is realized. Manufacturers claim an economizer can often reduce fuel requirements by 5 to 10%.
