Abstract:Combined with the thermal system analysis, the mathematical model for selecting the optimal initial pressure of the power unit is established based on the comprehensive consideration of the effect of main steam pressure on governing stage efficiency, steam feed pump consumption and flow passage efficiency. Then the steam pressure with the maximum unit efficiency is searched using variable condition calculation. With quantitative calculations of N600-16.7/537/537-I unit of Pan Shan thermal power plant taken as … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
