This is the industrial project based on the recovery of heat from exhaust flue gases. Exhaust flue gases from non-ox furnace at Continuous Galvalume line in JSW Steel Coated Products Ltd as observed leaves the furnace at 200C and is effluated to atmosphere through chimney. The advantage of recovering heat from flue gases of a propane fired non-ox furnace aiming to trap heat from enthalpy of flue gases released to the chimney at 200 degrees centigrade and proposes to accommodate the trapped heat to heat the air used in hot air dryer from ambient to 80 degrees centigrade, existing heat exchanger uses steam to elevate the temperature of air by regulating the mass flow rate of the flue gases. In this improvement technique the task is to heat ambient air using heat of flue gases averagely leaving the furnace at 200 degrees centigrade. The exhaust blower blows flue gases to heat exchanger at 55000m3/hr replacing steam in the existing heat exchanger using flue gases to use its enthalpy to better use. Existing system uses steam to increase the temperature of air, by cutting the supply of steam with exhaust flue gases we are able to use non-ox furnace to its fullest capacity. The proposed improvement eliminates the plants dependence on Coal and indirectly diminishes daily water consumption.
