The technique requires considerable financial investment as the pressurevessel has to withstand the internal gaspressure and allow the powder to be heated to high temperatures.
因为压力容器必须经受住内气压并允许粉末加热到较高温度，所以这种技术需要相当可观的资金投入。

The water inside a horizontal vessel is heated by fired burner through burning channel, and the natural gas or crude oil in tube bundle or highpressure coil are heated by hot water.
This paper introduces the structure characteristics and main designing technical parameters of the pressurevessel of Tsinghua University 10mw high temperature gas cooling reactor.
