Heat transfer is dependent on the mass flow of hot gases, mass flow of water or steam, temperature difference and surface area. A singlepressure HRSG can recover heat up to a specific level. If more heat is to be recovered, then the area of the heat exchanger increases, which soon becomes economically unfeasible.
