锅炉的水质情况是影响锅炉安全运行的关键因素,当然,水质检测也是锅炉检测中不可缺少的内容.锅炉水质的好坏,不仅会对锅炉使用单位的经济效益造成影响,同时还会影响到锅炉的传热性能.加强锅炉的水质检测对于锅炉的安全运行以及锅炉经济效益的提升有着很大的保障.锅炉生产运行中使用良好的水质能够减少其炉壁杂质的附着量,从而提高锅炉的热传导性能,进而降低能源的消耗.本文主要针对锅炉水质检测水平促进水质管理工作进行简要分析.

建立了BR0.015F型人字形板式换热器冷热双流道的流动与传热计算模型,并在此基础上对其分配区结构进行改造,建立了新的计算模型,利用计算流体力学软件对两换热器模型内流体的流动和传热进行了数值模拟,并对比了两模型内的速度场、温度场和压力场.结果表明:相同工况下,新模型的努塞尔数约等于原模型的,摩擦因子较原模型的减少了30％,强化比是原模型的1.1倍左右,整体性能较原模型有明显提高.

通过对我国工业锅炉运行情况和能效测试现状进行分析,对其存在的问题进行研究,并针对这些问题,提出相应的解决对策。

锅炉的排污与锅炉安全和节能密切相关,从现场检测及水质分析结果两方面入手,发现锅炉存在的过量排污问题,并提出相应的整改方案及节能效益分析,结果表明,正确合理的排污能够取得可观的节能效益。

The velocity field and temperature field in transversally corrugated tubes of different structure have been numerically simulated,according to the field synergetic principle,the terbulent heat transfer in three kinds of these transversally corrugated tubes has been analysed.Considering the difference of flow resistance is different type of said tubes,the heat transfer ability of said tube types has been comprehensively evaluated and compared,therefrom,the best tube type being obtained.Results of analysis show that the comprehensive heat transfer ability of the best tube type is up to about 1.3 times of that in commonly used transversally corrugated tubes under condition of inlet flow velocity being in a range of 0.5~3 m/s.
