After twenty two years of operation,the high temperature shift reactor has generated serious failure caused by hydrogen corrosion This paper analyses the reason of the hydrogen corrosion of the high temperature shift reactor Measures such as hydrogen diffusing and adding inner insulating layer were taken which have extended the service life of this equipment effectivel

With a thin-wall flame tube serving as an object of study,presented was a wall temperature calculation model and method for an air-film cooled flame tube with a heat insulation coating.

This paper deals with studies on process technology and quality control of a thick heat insulation coating material applied to a small supersonic vehicle.

Integrative design model and algorithm for nano-satellite s radiator surfaces and heat insulation layers;

To avoid a long nozzle (LN) of non-preheating from rupture, a heat insulation layer (HIL) with a lower coefficient of thermal conductivity (CTC) was compounded in the inner hole, and the thermal stress was investigated.
