蒸汽锅炉经过适当的改造可以作为热水锅炉使用。但是,为了确保安全运行,在设计改造时应考虑以下几项原则:1、尽量保持原有蒸汽锅炉自然循环的特性。2、改造工作量要小,尽量避免在锅筒上开孔。锅炉的承压元件需开孔时,应进行强度计算。3、锅炉受热面应能得到充分的冷却,减少各受 The steam boiler can be used as a hot water boiler after proper modification. However, in order to ensure safe operation, the following principles should be considered in the design and reconstruction: 1. Try to keep the original natural characteristics of the steam boiler. 2, the reconstruction workload is small, try to avoid opening holes in the drum. When the pressure components of the boiler need to be perforated, the strength calculation should be carried out. 3, the boiler heating surface should be able to get adequate cooling, reduce the sufferings
