Boiler Economizer Coil (Sometimes Called Economizer) is the Energy improving device that helps to reduce the cost of operation. Economizer coil is boiler feed-water heaters in which the heat from waste flue gases is recovered to raise the temperature of feed water supplied to the boiler, thereby increasing the Fuel Economy, Steaming Capacity, Life of the Boiler and Reducing Pollution.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 feed water. This raises the temperature of the boiler feed water, lowering the needed energy input, in turn reducing the firing rates needed for the rated boiler output.
We have fabricated various types Economizers Coils such as Plain Tubular Economizers, Finned Economizers Feed water heaters Evaporator Coils etc.by cold bending process on CNC tube bending machinewith booster which control the thinning and ovality of the bends.
To rectify the Erosion of the Eco-Coil tubes and mainly at bends, we also make Half Tubes Sleeves for upper tubes, SS full Sleeved tubes etc.
