Abstract:
In a hydrocarbon fueled reformed gas fuel cell system having a rated power, a process for cooling reformed gas from a fuel processor prior to feeding the reformed gas to a shift converter comprising the steps of:providing a cooling zone having a hot gas inlet, a cooled gas outlet and a water inlet; feeding the reformed gas at a temperature of between 800 to 1200Â°F. to the hot gas inlet; packing the cooling zone with a packing material; spraying water as droplets and contacting the droplets with the packing material and the reformed gas so as to cool the reformed gas and vaporize the water; and removing a stream of cooled reformed gas from the cooling zone wherein the cooled reformed gas is at a temperature between 400 and 500Â°F. and the stream is substantially free of water droplets.
