D2O (drain cooler)

Thermal economy analysis for drain cooler of thermodynamic system in power plant

疏水冷却器的热经济性分析

Comparative calculations of different drain methods show that it is more economical and safe to use the drain cooler for the low pressure regenerative heating system of 300 MW units than to use the low pressure drain pump.

对热力发电厂中低压加热器疏水系统所采用的不同疏水方式进行分析,通过对不同疏水方式的比较和计算,表明300 MW机组的低加回热系统采用疏水冷却器比采用低加疏水泵更经济、安全。

This time,design of steam cooler and drain cooler tubing system has had many changes,that compares with long since,the more rational structure,so much the better heat transfer efficiency.

介绍了为平旺发电厂200MW机组配套的蒸汽冷却器ZL-80、疏水冷却器SL-80的设计方案。

and the structure of feedwater intake tube-end ?DSZ ?DCZ and Drain Inlet etc.

简要介绍了哈锅300MW机组高压加热器发展概况及给水入口管端、过热蒸气冷却段出口部、疏水冷却段入口部、上级疏水入口等部件的结构特点。

Based on the comparison of the overall thermal performance calculation and the actual operating parameter due to dismantlement of external drain cooler,the paper got results that can be useful for optimizing operation for the defection external drain coolers used in early 200MW units.

早期投产的国产200MW机组因设备老化,其外置式疏水冷却器经常会产生汽侧筒体被蒸汽吹蚀及钢管泄漏等故障,影响了机组的安全运行和经济效益。
