Conference Article: Heat-exchanging components for coal gasification: He/He intermediate heat exchanger (IHX) and steam reformer (STR) in the primary circuit

Abstract

As compared with the conventional manufacture of apparatus, there are some essential differences due to the utilization of 950^oC hot helium from a HTR, installation in a PCRV, prevention of major failures, and long lifetime. The following basic solutions result from these essential features: Metallic tubular heat exchanger with extremely high wall temperatures. Precautionary measures (in-service inspections). Fully qualified material. Comprehensive analyses of the strength and creep behaviour. Comprehensive qualification tests of the component. The above-mentioned constructive features and the respective solutions are discussed with the He/He intermediate heat exchanger (IHX) and the steam reformer (StR) used as examples
