| 中文摘要: |
| 论述了大容量热水锅炉用于集中供热的优势。对29MW角管式热水锅炉的水动力特性进行了详细分析，并提出在应用自然循环与强制循环相结合的循环方式时，既要考虑自然循环的可靠性及强制循环的安全有效性，又要避免尾部受热面的低温腐蚀。与国内其他炉型相比，29MW角管式热水锅炉具有整体优势，在我国西部大开发中该炉型将有广阔的发展前景。 |
| 英文摘要: |
| In this paper, illustrated was the advantage of large-capacity hot-water boilers for district heating over other type of installations. Hydraulic calculations and an analysis of the hydraulic characteristics were conducted for a 29 MW corner-tube type hot-water boiler. In applying natural circulation coupled with forced circulation in the boiler circulation system, the reliability of the natural circulation loop and the safety and effectiveness of the forced circulation loop ought to be considered as well as the prevention of boiler back-end heating surfaces against low temperature corrosion. Compared with other domestic boiler installations, this type boiler has technical advantage and will find wide applications in China, especially in the west of the country. |
