2. A waste heat recovery boiler produces 4.8MPA (dry saturated) steam from 103 deg C feedwater. The boiler receives energy from 6 kg/s of 945 deg C dry air. After passing through a waste heat boiler, the temperature of the air has been reduced to 343 deg C. How much steam in kg is produced per second? (Hint: Approximate Enthalpy of Water in kJ/kg Cp (t); where t is in °C) @4.8 MPa dry saturated: h = 2796
