为了监视和控制燃烧过程,过去曾把烟道气中的CO_2视为很有用的气体。但是今天,由于氧化锆探头的发展,监测烟道气中的氧量变得越来越普遍。利用烟气中的含氧量能测量出从烟囱跑掉了多少热空气,同时还能表示出锅炉燃烧的总效率。如果在监测烟道氧的同时,对CO和一些可燃气体也进行监测,则能得到炉子的燃料/空气比,这样对炉内发生的情况就有了清楚的了解,进而利用控制系统可使燃烧过
For the purpose of monitoring and controlling the combustion process, CO 2 in the flue gas was used as a very useful gas in the past. But today, due to the development of zirconia probes, it is becoming more and more common to monitor the amount of oxygen in the flue gas. Using the oxygen content of the flue gas it is possible to measure how much hot air has run away from the stack and at the same time to show the overall efficiency of the boiler combustion. If the CO and some combustible gases are also monitored while monitoring the oxygen in the flue gas, the fuel / air ratio of the furnace can be obtained so that a clear understanding of what is going on in the furnace is obtained and the control system can be used to burn Too
