ABSTRACT:
Heat exchanger 4 operates in counterflow relationship to cool reformed gas and to heat raw gas during operation with gaseous raw fuel feed. It also operates in counterflow relationship when preheating the system while recirculating inert gas. This same heat exchanger 4 operates in parallel flow relationship when liquid raw fuel is to be vaporized. Only one heat exchanger is required while avoiding cracking and fouling in the heat exchanger.
