1999—2000年度采暖期，荣成市在黎明、三环和新庄三个居民生活小区实行循环水供暖，供暖面积为20万平方米。　　循环水供暖，就是调整热电厂设备运行方式，回收过去在冷却塔内浪费的汽化潜能，来提高循环水的温度。与传统的热电蒸汽供暖方式相比，循环水供暖的最大优点就是可 During the heating period 1999-2000, Rongcheng City implemented circulating water heating in the residential areas of Liming, Sanhuan and Xinzhuang, and the heating area was 200,000 square meters. Circulating water heating is to adjust the operation mode of thermal power plant equipment and recycle the vaporization potential that was wasted in the cooling tower in the past to increase the temperature of circulating water. Compared with traditional thermoelectric steam heating, the biggest advantage of circulating water heating is that
