16 4. Innovative project: Infrared curing of Magnesium Oxide coating on CRGO coils (Jan.18) To achieve uniform and controlled curing, 16 infrared burners are installed with LPG as a fuel. Instead of warming the air like other conventional heaters, infrared heaters heat objects directly in their paths. Infrared heaters use a substantially lower amount of energy by 5-10 % than conventional heaters. The infrared rays emitted are easily absorbed by the coated strip which results into instant curing. This concept is taken from group company. They are having ceramic burner and we have put metal fiber burner. Before Warming Air Annual Production (MT) Annual savings Lakhs m 3 /annum LPG - MT Lakhs Rs. t CO , This concept can be implemented for drying application of various types of coatings on flat steel.

18 6. Utilization of waste: Use of excess vent Hydrogen gas as a fuel The consumption of Hydrogen gas in the plant is less than the minimum generation capacity i.e. 240 Nm 3 /Hr. This depends on number of furnace in use as per market demand. The excess hydrogen is being vented into atmosphere to maintain plant operations. Valuable energy is thus being vented. We had installed new control scheme so that vent Hydrogen is used in a reformer burner as a fuel to save main LPG fuel. Excess Hydrogen used as a fuel Year NM 3 MkCal , , , Average 62, Resulted in LPG saving of 14.7 MT/annum (5.6 Lakhs Rs./annum.)
