The traditional deaerator structure is statically determinate structure. However,as the geometry size of deaerator increases,the double bracing can not satisfy the strength and many other engineering demands. To increase the number of the redundant braces is one way to solve the problem. To the consideration of the safety,the primary work is to obtain the reliability index. The deaerator parameters can be designed based on the result of reliability and the reliability sensitivity,which is finished before application of the deaerator. High reliability is expected,so the parameters design method of deaerator structure is focused in this paper,the results show that the parameters can be designed to obtain adequate reliability.
