Answer to Question #311087 in Mechanical Engineering for john Smith

Question

During a test on a boiler the following data were recorded: Pressure = 1.7 MPa Steam temperature at exit = 240ºC Steam flow rate = 5.4 tonnes/hour Fuel consumption = 400 kg/hour Lower calorific value of fuel = 40 MJ/kg Temperature of feedwater = 38ºC Specific heat capacity of superheated steam = 2100 J/kg.K Specific heat capacity of liquid water = 4200 J/kg.K. Calculate: 5.1 Efficiency of the boiler. 5.2 Equivalent evaporation (EE) of the boiler [91 %; 16.1]
