热水采暖在节约燃料方面的优越性已日益受到热能工作者的重视,我国北方采暖区应普遍采用热水锅炉。但是我国热水锅炉尚未形成系列产品,现有热水锅炉品种及其煤种适应范围尚满足不了大面积替代工业锅炉更新设备的要求,另一方面又受投资及技术上的限制。所以近期内将现有蒸汽锅炉改成热水采暖锅炉将是一项重要的措施,如能在现有工业锅炉系列的基础上发展热水锅炉,将有助于热水采暖的推广应用和积累经验。然而在水动力特性和结构特点上,蒸汽锅炉
The superiority of hot water heating in saving fuel has been paid more and more attention by the thermal energy workers. The hot water boiler should be widely used in the heating area of northern China. However, the hot water boiler in our country has not yet formed a series of products. The existing hot water boiler varieties and their coal types can not meet the requirements of large-scale replacement of industrial boiler renewals. On the other hand, they are subject to investment and technical restrictions. Therefore, it is an important measure to change the existing steam boilers to hot water heating boilers in the near future. For example, the development of hot water boilers based on the existing industrial boilers series will help popularize and accumulate hot water heating experience. However, in terms of hydrodynamic characteristics and structural features, steam boilers
