Abstract
A waste heat boiler for cooling hot syngas in heat exchange with water under boiling pressure, consists of an outer pressure shell ( ) having a water space ( ) filled with boiling water up to a predetermined fluid level ( ) and a steam space ( ) above it. In the water space ( ), heat exchanger tubes ( ) are arranged, through which the syngas to be cooled flows. Downstream from the heat exchanger tubes ( ) is a superheater for superheating the saturated steam generated by the boiling water. This superheater is positioned at least partially in the steam space ( ) above the fluid level ( ) and has straight tubes ( ), through which the syngas coming from the heat exchanger tubes ( ) flows and around which the steam exiting from the water space ( ) circulates.
