The Application of The Reliability Principle for Single or Two Set Equipment in The Heating Power Plant to Choose

In this paper, calculated by applying the principles analysis of single set or two set equipment, combined with the reliability of calculation of a typical 350MW heating power plant in the heating condition and non-heating condition, the initial judge and analysis reliability and economic of unit for two set or single set equipment, the result of conclusion that the project will set up two 50 percent equipment, which be the maximum reliability and the least loss.
