Strategy Economic Analysis Of 600M Wunit Operation And Quality Control In Construction Process

This topic aimed at the thermodynamic system of a 600MW supercritical unit, mainly included steam turbine and boiler, using software for energy consumptionto calculate major performance index of thermodynamic system in detail. Contrasted with former thermal experimental data, I have analyzed the conclusions of experiments and calculation. In the process of calculating turbine heat rate, this topic proposed the issue that the plant makes the flow of condensed water as standard flow. And I use actual flow as the standard to find out the problems in turbine thermodynamic system by experiments and calculation. Besides that, this topic put forward optimizing suggestions. By analyzing the results of testing and calculating boiler efficiency, we find out that there are some problems about coal-air ratio, air leakage rate of air pre-heater, primary air, secondary air and point out the influence of these problem to heat economy of unit and adopted optimizing method. Though detailed calculation and analyzing existing problems, we can provide technology support and guarantee for the unit later safe and economy running.This topic focuses on quality control during designing, construction and acceptance of steam turbine. Then analysis the characteristics of the thermal power plant steam turbine construction project in detail. On this basis, demonstrate the quality characteristics of the steam turbine construction project. The quality control in designing, constructing and accepting of steam turbine is analyzed from the perspectives such as the factors affecting construction, the forming pathways of real project and the quality forming process...
