Study On The Operational Performance Of Air-cooling Cold-end System For 200MW Units

This paper makes out detailed analyse and research for operational performance of air-cooling cold-end system, based on the acquired production inside and abroad and the practice of fengzhen power plant. Start with the pressure of steam condenser, consider integrately condition factors such as wind velocity, wind orientation and circumstance temperature, found the calculation model of condensation pressure for air-cooling cold-end system. And then, confirm its influence factors, and get influence relations of operation thermo-economics for air-cooling units, and utilize practice performance data of 200MW air-cooling cold-end system, validate the calculation model. Results of application show that this calculation model can exactly confirm the performance status comparatively and provide instructional actions for power plant's optimizing operation.
