福建省电力中心试验所在杏林发电厂的支持和协作下,于1976年9月在杏林发电厂1号炉上进行了空气预热器烟气露点的测试。试验时使用的导电式露点测定仪是根据有关资料自行装配的,试验时水平置于空气预热器的烟道中,探头伸入烟道1米。用XWD 1-200型晶体管双笔连续记录自动电位差计记录玻璃探头热电偶所指示的温度,经用水银标准温度计校正,即是烟气的露点温度。
With the support and collaboration of the Xinglin Power Plant, Fujian Power Center Experimental Station was tested on the air preheater flue gas dew point at Xinglin Power Plant No. 1 furnace in September 1976. Conducted dew point test instrument used in the test is based on the information assembled, the level of the test placed in the air preheater flue, the probe into the flue 1 meter. Record the temperature indicated by the thermocouple of the glass probe with the XWD 1-200 Transistor double potentiometer continuously calibrated with mercury standard thermometer, which is the dew point temperature of the flue gas.
