Hydrogen is assumed as one of the most environmentally benign fuels. By the combustion of hydrogen enormous amount of H2O; and therefore, latent heat is produced. Because, there is not so much need to heat at low temperatures, methods are needed to recover latent heat at higher temperatures. One of the methods to upgrade the latent heat at higher temperatures is the method of combustion at elevated pressures. Increasing the pressure of the exhaust gas makes it possible to recover latent heat and higher extra exergy output from the system. In this work, both latent and sensible heat recoveries at elevated pressures are investigated using environmentally friendly fuel hydrogen. It is shown that coefficient of performance (COP) and exergy efficiency (n(ex)) is very satisfactory even at high pressures. (C)2017 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
