How much energy is required to raise 63 kg of ice at 0 degrees C to saturated steam at 100 degrees C. Specific heat capacity of water is 4.2 kJ/kg K. Specific latent heat of ice is 335 kJ/kg. Specific latent heat of steam is 2,257 kJ/kg.
A boiler furnace releases 10000.000 kJ of heat for each kg of fuel burned and produces dry saturated steam at 11000.000 kPa from feedwater at 250.000 degrees Celsius. How many kg of steam will be produced for each kg of fuel burned if the boiler had an efficiency of 70.000%.
