Boiler Economiser Coil (Sometimes Called Economizer) is the Energy improving device that helps to reduce the cost of operation
If the exhaust gases which are leaving the Boiler at such high temperature is made to pass through the Economiser Coil in order to provide the required sensible heat to the water by increasing its temperature, it will reduce the heat load on the boiler to the greater extent.
A common application of economizers coil in steam power plants is to capture the waste heat from boiler stack gases (flue gas) and transfer it to the boiler feedwater. This raises the temperature of the boiler feedwater, lowering the needed energy input, in turn reducing the firing rates needed for the rated boiler output.
Area of Uses For Economizer Coil :
It is used in all modern plants. The use of economizer coil results in saving fuel consumption increases steaming rate and boiler efficiency.
