本文针对ＣＢ油炉在燃用国内高粘度重油时排烟中烟尘浓度超标问题，进行了试验研究和分析。结果表明，烟尘排放超标的实质在于排烟中含有大量未燃烬碳粒，其根本原因在于燃油的运行粘度太大，油的雾化粒度较粗，炉内过量空气不合理等因素导致燃烧不完全所致。在采用了一系列改善燃油雾化质量、改进炉内燃烧的技改措施后，该炉排烟中烟尘浓度降低了８１％ 左右，已达到一类地区所允许的排放要求。
In this paper, CB oil furnace in the combustion of domestic high viscosity heavy oil exhaust smoke concentration exceeds the standard, conducted a pilot study and analysis. The results show that the essence of excessive soot emissions is that the smoke contains a large amount of unburned carbon eutectics. The fundamental reason is that the running viscosity of the fuel is too high, the coarse particle size of the oil atomizes, and the unreasonable excess air in the furnace leads to the combustion Completely caused. After adopting a series of technical improvement measures to improve the quality of fuel atomization and improve the combustion in the furnace, the concentration of soot in the furnace smoke was reduced by about 81%, and the emission requirements allowed by a type of area have been met.
