It summarizes the commissioning work, which includes the adjustment of the air compressor,the system＇s naked cooling,the precooling system and the operation adjustment. It also provides detailed analyses on some failures which occurred in the commissioning. Through the modification of the design and the interlocks, the tripping probability of the air compressor was greatly reduced. Through the heating of the system and the control of the water cooler＇s nitrogen flow,the overproof content of carbon dioxide and fluctuation of oxygen flow were avoided. Nitrogen-block in the argon system was eliminated by the precise control of the argon rectification flow and argon content. All these solutions have been proved to be effective by practice.展开更多

Tianjin Beijiang Power Plant, one of the first series of Circular Economy Demonstration Project in the country, successfully put its second unit into operation on November 30, 2009
The 200 MW thermal power unit of Yaugzonghai Reconstruction Project phase I was commissioned and put into system operation on 17th November 1996, it is the first 200 MW thermal unit in operation in Yunnan Province.
