A steam pipeline of 250 mm outer diameter & 100 meters long is insulated with 150 mm Mineral wool insulation. As an energy conservation measure, the management has upgraded the existing Mineral wool insulation with efficient calcium silicate insulation. Calculate the economics in terms of payback if the insulation is upgraded at a cost of 20 lakhs. Given: Operating hours: 8000 Boiler efficiency: 87 % Fuel Oil Cost: Rs. 45,000 per ton GCV of the fuel: 10,200 kcal/kg Thickness of Mineral wool insulation: 150 mm
