锅炉机械化问题,是我国当前大型海船面临的重要工作。而改装煤粉炉是解决这个问题的主要途径之一。本文详细的介绍了“和平一号”轮锅炉本体改装状况及采用喷咀、煤粉系统,运煤除灰系统的结构形式。由于这是我国首次尝试,问题很多,所以文中特别阐明了在设计过程中是如何把理论和实际情况结合起来,创造性的解决这些问题的。文章最后对改装设计中尚存在问题及今后大型海船炉锅发展趋势作了扼要的分析与讨论。
The mechanization of the boiler is an important task confronting the large-scale sea-going vessels in our country today. The conversion of pulverized coal furnace is one of the main ways to solve this problem. This paper introduces in detail the modification of the “Heihe No. 1” boiler body and the structure of the nozzle, pulverized coal system and coal ash removal system. Since this is the first attempt in our country and there are many problems, the article particularly states how to combine the theory with the actual situation in the design process and creatively solve these problems. The article concludes with a brief analysis and discussion on the existing problems in retrofit design and the future development trend of large-scale sea-ship boiler.
