Freezing Problems and Solutions for Direct ACC System in Large Electric Power Plant |
| |
| Abstract: | The operation of direct air-cooling condenser （ACC） system was analyzed on a case in point freezing of the condensation, combined the theory with the practice of Huadian Ningxia Lingwu electric power Co. Ltd., the preliminary solutions taken to prevent the above mentioned problems were proposed. The results show that the freezing problems of direct ACC can be partially overcome and economic operation level can be upgrade by reasonable design of the air-cooling island, optimum adjustment of the cooling air flow in different ambient air temperature. |
