heat exchange surface meaning in English
换热表面
热交换面
Examples
- Usually , soot blowers are used in large boilers to clean heat exchange surfaces
通常，大型锅炉都装有吹灰装置来清洁受热面，因此需要消耗大量的能量。 - During operation of coal fueled power plant boiler , heat exchange surfaces will be polluted by soot accumulation . this seriously weakened the heat transfer capability from gas to working fluid
在电站燃煤锅炉的运行过程中，受热面必然会产生积灰污染，这就大大削弱了烟气对工质的传热能力。 - Large amount of energy are consumed during soot blower operation , and frequent unsuitable soot may damage or shorten the life of heat exchange surfaces because of wear and thermal stress . at the same time , the maintenance cost of soot blowers are increased
另外，不适当的频繁吹灰会因磨损和热应力对受热面造成损坏，从而缩短受热面的寿命，同时也增加了吹灰装置的维修费用。 - After the optimizing system is put into operation , online calculating results and operation effect is analyzed , pointing out that the base for the whole boiler soot blow optimization is the minimum loss of soot accumulation and energy consumption of soot blowing , the base for water cooling wall soot blow optimization is the combustion house outlet gas temperature difference , the base for a single heat exchange surface soot blow optimization is the degree of its soot accumulation
并对优化系统在线运行后，取得的实时计算结果和实际效果进行了分析，着重指出积灰和吹灰的经济性最佳可作为整个锅炉吹灰优化的决策依据，炉膛出口烟温差可以作为炉膛吹灰优化决策的依据，受热面灰污程度可以作为单个对流受热面吹灰优化决策的依据。 - This paper has analyzed and synthesized the problems of burning heavy viscosity petroleum about injecting steam boilers in liaohe oil field . the heat balance experiments on injecting steam boilers burning heavy viscosity petroleum is made first . the main causes of low thermal efficiency and heat lose of flue gas are the poor effect of atomization and burning with old - fashioned oil nozzles , worse ash gathered on . heat exchange surface and high temperature of flue gas
本论文在分析综述了辽河油田注汽锅炉燃用高粘度稠油时存在的问题的基础上，首先对燃用稠油的注汽锅炉进行了正、反热平衡试验，分析了注汽炉热效率偏低、排烟热损失偏高的主要原因是原喷油嘴改烧高粘度稠油时雾化和燃烧效果差、换热面积灰严重、排烟温度太高。
