ash concentration meaning in Chinese
烟灰浓度
Examples
- Firstly , simulate flow field of rear smoke channel , plot velocity magnitude and ash concentration distribution in section of entry of heat pipe air preheater , compare with data which were measured in guiyang power station , verify simulation to be reasonable and right . secondly , simulate all kinds of factors which affect flow field ' s uniformity such as length , thickness , location of diffluent board , ash concentration , ash diameter , and so on , find the chiefly factors . thirdly , install guide board in curve channel in rear smoke channel , then simulate its " flow field , plot velocity magnitude and ash concentration distribution
在此基础上模拟在冬夏两季不同情况下，不同流速对热管空气预热器壁面温度的影响；然后对影响整个流场分布的各种因素：包括分流板长度、厚度、偏离中心流道位置的偏离度、飞灰浓度、飞灰粒径等因素进行数值模拟；最后提出在分流烟道转弯处加装导流板，并模拟加装导流板后的流场分布，得到下级空气预热器出口、热管空气预热器进口处的断面速度场分布、浓度场分布，以论证加装导流板能达到流场均匀化的作用。 - This paper also analyzes the ash wear mechanism , and then does the effects of low temperature economizer wear five factors : the first is the smoke corridor caused by wear mechanism , the second is the impact on the wall material , and the third is that of flying ash concentration , the fourth of the excess air ratio , and the fifth is the change in the composition of the gas to wear the impact
分析了飞灰磨损的机理，然后分析了影响低温省煤器磨损的5种因素，一是烟气走廊引起磨损的机理；二是管壁材料的影响；三是飞灰浓度的影响；四是过量空气系数的影响；五是烟气成分的变化对磨损的影响。 - There will appear a very uneven flow field , and appear a very big velocity magnitude distribution and ash concentration distribution near back wall . thus , the velocity magnitude is far bigger than that of optimal design velocity magnitude , which will lead to serious wear and tear in metal face of heater . especially , because of curve structure in front of heat pipe air preheater , there is more serious wear and tear
由于靠近竖井后墙面的烟气流速很大，飞灰浓度也较大，断面速度分布的最大速度大于最佳设计速度的2 - 3倍，这样将造成受热面的严重磨损，特别是热管空气预热器前端烟道的几何结构有一定的转角，更增加了磨损的程度。
