| 摘 要： | 由于火焰烟温的脉动性使得无法采用常规的3热电偶法测定真实的烟气温度。采用3热电偶法测量火焰温度时,实时测量热电偶的时间常数,对热电偶测量值进行动态补偿。测试结果表明:3热电偶测量值的相对标准偏差小于3 5%,与抽气热电偶测量值的相对偏差小于±4%。具有较好的重复性和较高的准确性,能够用于测量炉膛内真实的火焰温度。

| Abstract: | Because of the pulsation of furnace gas temperature, it is impossible to measure the real gas temperature using normal three-thermocouple. Three-thermocouple is used as basic method to measure the furnace gas temperature, and dynamic compensate the measuring value with dynamic time constant. The result of experiment has proved that the relative standard deviation of the figures got by several times is below 3.5%, the relative deviation between the values got by three-thermocouple and air extracting thermocouple is below 4%. The figure measured by this way is tally with the fact. |
