A gas turbine used for power generation is producing 57MW of power. The turbine’s exhaust temperature is 541°C at a mass flow rate of 132.8 kg/s and is currently emitted to the atmosphere.

Your task is to design a heat exchanger that recovers the waste heat from the exhaust. The recovered heat is to be used to heat water from 40°C to 60°C for use in a closed-loop hydronic heating system for an office building. The heat exchanger is to be placed between the gas turbine’s exhaust and the attached power generator. To not interfere with the power generator, the pressure drop across the hot flow path should not exceed 600Pa. The maximum gas mass flow rate possible through the heat exchanger has been restricted to 4% of the exhaust gas flow rate of the turbine.
