ABSTRACT:
A system and method for recovering heat from dirty gaseous fuel (syngas), wherein the pressure of clean fuel gas is elevated to a pressure higher than that of the dirty syngas and then the pressurized clean fuel gas is fed to a heat recovery unit for heat exchange with the dirty syngas. Consequently, in the event of a leak in the heat recovery unit, the flow is from the clean fuel side to the dirty syngas side, thereby avoiding the possibility of contamination of the clean fuel gas.
