Material Selection Of The Four Main Pipelines For 1000mW Ultra Supercritical Unit

摘要：

The power plant boiler mainly constitutes of pipelines for the main steam, hot sections of the reheated steam, cold sections of the reheated steam and the high pressure feed water. Material selection of the four main pipelines will have a marked effect on the security and economy of the power plant operation. The main steam pressure of the 1000MW ultra supercritical unit in Tianjin SDIC Jinneng Electric Power CO.LTD is 27.56MPa, and the main steam temperature is 605°C . It puts forward the high mechanical performance and high temperature performance of the four main pipelines. The thermal stress, coefficient of the heat expansion, operation reliability and the economy, and the compositions of the four main pipelines material selection should be taken into account when demonstration is processed.
