用大型热水锅炉采暖,在我国还没有广泛采用,目前许多地区,还采用蒸气采暖。我国生产的热水锅炉,供热量都在10百万千卡/时以下,而国外热水锅炉的最大容量已达到180百万千卡/时以上。根据我国东北地区采用热水锅炉采暖的实践和国外的经验,热水锅炉采暖与蒸气锅炉相比,有节能和节约制造锅炉用钢材的优点,值得在我国推广。一、热水锅炉采暖的节能分析热水采暖和蒸气采暖比较,可以节约燃料20—30%左右,表1为热水采暖和蒸气采暖的
The use of large-scale hot water boiler heating has not been widely adopted in China. At present, steam heating is also used in many areas. The heat boilers produced in China have a heat supply capacity of 10 million kcal/hour or less, while the maximum capacity of foreign hot water boilers has reached 180 million kcal/hour. According to the practice of using hot water boiler heating in northeastern China and foreign experience, compared with steam boilers, hot water boilers have the advantages of saving energy and saving steel materials for boiler production and are worthy of promotion in our country. I. Energy-saving analysis of hot-water boiler heating Compared with hot-water heating and steam heating, about 20-30% of fuel can be saved. Table 1 shows the heating of hot water and steam heating.
