Principle of Operation
The hot flue gases from Boiler / Thermic Fluid Fleater / Furnaces, enter the Economiser vertically spread in a uniform flow proportionally across the entire economizer with specially designed gas distribution system. Using this heat energy in exhaust gases, the feed water going to the boiler is heated to desired temperature.
This is a cross flow function i.e. flue gases flows from top to bottom vertically & water passes through the tubes / headers horizontally, to get the best results of Heat Transfer.
The efficiency of the Economiser is considered as close as 100% since the total gas coming to the economiser is cooled down to a pre-determined outlet temperature. Thus, maximum possible heat in the flue gas is utilized to heat the feed water, the water at elevated temperature is then fed to boiler.
The pressure drop across gas side / water side is well designed and maintained to avoid any back pressure on the boilers & feed water pump. Max pressure drop across water side is maintained at 0.2 kg/cm2 and on gas side it is maintained below 35 mm of WG.
