We R K Industrial Enterprises specialize in designing and developing recuperators for utilization of waste heat generated from industrial furnaces. The temperature of flue gases generated by industrial furnaces varies from 600�C to 950�C. Thus, a good amount of heat energy, varying between 35 to 42% of the heat input to the furnace, goes to the atmosphere and is a waste. A good part of this waste heat can be recovered by recuperator manufactured by us. Our recuperators preheat the combustion air from the escaping gases to 400�C temperature approximately and thus recycles the waste heat and diverts it to the furnace and saves fuel oil.
