Jun 17, 2018 · The economizer is used for heating and controlling the heat level of energy coming out from the the super heater or re-heater. It uses the energy for heating the feed water coming from the pump to the boiler. The super heater is an important part of the boilers in the power plant where is used for improving the efficiency level of the power plant.

Economizer. Economizers (as well as air heaters) perform a key function in providing high overall boiler thermal efficiency by recovering low level (i.e., low temperature) energy from the flue gas. For each 40F (22C) that the flue gas is cooled by an economizer or air heater in a conventional boiler with air as the oxidant and normal excess air, the overall boiler efficiency typically increases by approximately 1%.

The economizer is the heating surface in the tail flue of the boiler that heats the boiler feed water into saturated water under the pressure of the steam drum. Because it absorbs relatively low temperature flue gas, it reduces the flue gas exhaust temperature and saves It improves energy and

Definition of Economizer? An economiser 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 chimney.

Jan 15, 2019 · A steam boiler is designed to absorb the maximum amount of heat released from the process of combustion. There are three way (Radiation, convection & Conduction) that heat is transfer in the boiler and relative percentage of each heat transfer within system boiler is dependent on the type of steam boiler, fuels and the designed transfer surface. 1.

Jul 29, 2009 · To increase the efficiency of the boiler, the feed water that enters the boiler is pre-heated with the help of an economizer through which the feed water passes before entering the boiler. The exhaust gas of the boiler is also put to use by making it pass over an air heater, which heats up the combustion air entering the furnace.

May 31, 2010 · Boiler Economizer is usually fitted to increase the efficiency of the boiler by increasing the heat recovery surface so that the maximum amount of heat is recovered from the burnt gases. This is achieved by heating the feed water to the boiler from the burnt gas before it leaves the furnace. In this article we discus the inspection carried out in the economizer and on it gas side of the boiler.
