葫芦岛市生物质能燃料改善大气环境的探讨

分散在中小城市的小型洗浴锅炉,点多面广,锅炉燃料经历了原煤散烧、型煤、焦碳等不同阶段。虽然对其燃烧过程及其排放烟气进行了严格的管理、治理,但是燃烧产生的烟尘浓度、黑度、SO2经常超标排放,严重污染了大气环境质量。结合这种现状,通过改造锅炉结构,燃烧生物质颗粒燃料,实现了洗浴锅炉各种大气污染物达标排放,解决了市区四处冒黑烟的问题,改善了大气环境质量。

Small bath boilers widely distributed in small and medium cities.The fuels of small bath boilers have experienced three stages：scatter burning,coal and coke.Although strict managements and control measures have been adopted on combustion process and emissions,excessive missions of dust concentration,blackness and sulfur dioxide also seriously polluted the atmospheric environment quality.Through changing the boiler structure and burning of biomass fuel,the atmospheric pollutants emission of small bath boilers is up to the standards.Meanwhile,the problem of black smoke around the urban area has been solved,and that also improved the atmospheric environmental quality.
