Given the distribution feature of resources such as co.l and water, the requirements for the development of Chinese power industry, and the fact of monopoly by foreign co.panies, it is very necessary and significant to independently research and develop air-co.ling technologies. Through experimental research, simulative calculation, process and equipment development, field tests and a demonstration project, the design and operation technologies for air-co.ling system are grasped and relevant key equipment is developed. The results of the demonstration project show that the technical indicators for the air-co.ling system have met or exceeded the design requirements. Part of the research results have been inco.porated into the relevant national design standards. The technologies developed have been applied to more than 23 sets of thermal power units of or above 600 MW in China.
