The basic procedure of the system is: mechanical draft cooling tower basin, cooling tower collecting basin, water absorption front basin, condensate pump, water supply pipe, condenser/auxiliary engine cooling water system, return line and mechanical draft cooling tower. The circulating water system of the project adopts mechanical cooling tower recycling water system matched with four mechanical draft cooling towers, 5×25% sets of horizontal type circulating water pumps, in which four sets are in working condition with one as standby. The feed water for circulating water is from industrial water supply pipe line of the former plant. 主要技术规范： Main technical regulation:
