The heating value of the a dry fuel is 18 MJ/kg. a) Calculate the effective heating value of a fuel with 40% moisture and no flue gas condensation. b) Calculate the heating value of a fuel with 40% moisture and flue gas condensation Evaporation enthalpy H=2257 kJ/kg. Cp=4,2 ( kJ/kg,K) The heating value of a moist fuel is given by this formula: H=H0*(1-f)-f*2,6 (MJ/kg), H0=heating value of dry fuel, f=fraction of water.

Engineering Related problems: We assess the efficiency of two methods of chemical energy storage.I. First, we store the energy as natural gas (methane, CH4) and utilize it via combustion. We assume thefollowing efficiencies: electrolysis 70%, water-gas shift reaction 75%, natural gas storage andcirculation 80%, Fischer–Tropsch reaction 80%, combustion 75%. Based on these efficiencies, calculatethe efficiency of the total process.II. Secondly, we want to store the energy as hydrogen and utilize it via a fuel cell. We assume thefollowing efficiencies: electrolysis 70%, hydrogen storage and circulation 70%, fuel cell 50%. Calculatethe efficiency of the total process.III. Which of the two methods would you choose to use the hydrogen produced during electrolysis?
