摘要：
The waste heat boiler acts effectively as a kind of heat exchanger. It is widely used in petroleum industry, chemical industry, fertilizer industry, light industry, atomic energy installation and so on. The tubesheet is one of important components. In this paper, the numerical analysis and experimental research are carried out to obtain the stress of the new type Omega-tubesheet in waste heat boiler and the stress distribution of Omega-tubesheet. It is indicated that the stress state of the Omega-tubesheet can be enhanced by changing the conventional whole-circle tubesheet into the composed structure to both the high and low temperature tubesheet.
