CRUDE GAS COOLING SYSTEM FOR A FUEL SUPPLY PLANT

摘要

A crude gas cooling system (1) for a fuel gasification plant by means of which crude gas can be produced as the product of gasification of a fuel comprises a first steam generator (4), a second steam generator (8) and a first heat exchange unit (12) which are connected in series or in parallel and through which the crude gas can flow one after the other. The second steam generator (8) is arranged downstream of the first steam generator (4) and is adapted to generate steam the pressure level of which is lower than the steam that can be generated by the first steam generator (4). The first heat exchange unit (12) is arranged downstream of the second steam generator and is adapted to heat a process fluid in a process fluid circuit (14). A fuel gasification plant for a combined cycle power plant by means of which crude gas can be produced as the product of gasification comprises a crude gas cooling system (1). The combined cycle power plant comprises the fuel supply plant according to the invention.
