 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. 189,756 kJ A boiler furnace releases 13400.000 kJ of heat for each kg of fuel burned and produces dry saturated steam at 9000.000 kPa from feedwater at 190.000 degrees Celsius. How many kg of steam will be produced for each kg of fuel burned if the boiler had an efficiency of 67.000%. 4.641 Wet steam: contains all the sensible heat of the liquid and only part of the latent heat of vaporization The total enthalpy of 16.000 kg of steam at 900.000 kPa is 34633.600 kJ. Determine the dryness of the steam. 70% During a boiler test, a boiler burned 106.503 kg of coal with a heating value of 26000.000 kJ/kg. The boiler generated 1000.000 kg of dry steam at 10000.000 kPa at saturated condition, from feedwater at 160.000 degrees Celsius. Determine the boiler efficiency. 74.001% 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%. 4.32
