Technical And Econimic Analysis For Air-cooled Units Of Lingwu Power Plant Phase Ⅱ Project

This article on the basis of the national current electric power condition as well as in the Ningxia area electric power condition full investigation and study foundation, has analyzed the lingwu area resources, the environment situation and the national electric power development industrial policy, has obtained the Ningxia lingwu power plant second phased project construction feasibility, the necessity and the superiority.This article has carried on the analysis to the air cooled unit's thermal energy characteristic; To 3×660MW the supercritical direct air cooled unit and 2×1000MW the ultra supercritical direct air cooled unit two kind of plan technological advance degrees, the saving water effect, the thermal efficiency, the economic efficiency, have carried on the generalized analysis comparison, has recommended the Ningxia lingwu power plant two issue of air cooled unit's whole installing equipment technology plan. The project was designed and optimized based on the results above.
