Abstract
Energy efficiency policy analysis in the heat transfers process can be done in three ways, namely by means of emission / radiation, by means of flow / convection, and by means of propagation or conduction. The surface of the water in the boiler is printed at least 100 mm above the wall of the boiler, for the boiler to be fixed on land. As for the steam boiler carried, the minimum distance between the lowest water level and the highest part of the boiler that is still touched on by fire / smoke gas is 250 mm. The heat needed from 290C to 900C to heat 14 kg of water is 3,584 kilo joules. The amount of heat needed in the heat transfer available through the heat transfer process with a capacity of 2 tons per hour is 5,862,000 kilo joules per hour.
