摘要:
为探究商业成型燃料燃烧颗粒物排放特性,采用立式固定床反应器进行砂光粉、棉秆、竹屑的燃烧试验,分析燃烧颗粒物粒径分布规律和主要元素组成,并探讨各元素含量对颗粒物排放的影响。 结果表明:PM10 的排放量从高到低依次为棉秆、砂光粉和竹屑,排放量分别为 27. 76,20. 83 和 9. 65 mg / m3。 3 种成型燃料产生的颗粒物均以亚微米颗粒物 PM1 为主,PM1 在 PM10 中占比均超过 90%。 其中,PM1 主要以碱金属氯化物和硫化物为主,PM1-10主要以 Ca、Mg 硅酸盐为主。 相关性分析表明生物质灰含量与 PM1 排放量正相关,而 Mg+Ca 的质量分数、(Mg+Ca)与 Si 物质的量之比与 PM1-10 排放量正相关。
Abstract:
In order to investigate particulate matter ( PM) emission characteristics from the combustion of commercial biomass pellet, a fixed-bed reactor was used to conduct combustion experiments of wood dust, cotton stalk andbamboo dust. The particle size distributions and main element composition of PM were analyzed. And the influenceof element content on PM emission was discussed. It was found that the yields of PM10from high to low was cottonstalk, wood dust and bamboo dust, and the yields were 27. 76, 20. 83 and 9. 65 mg / m3, respectively. The PMswere mainly composed of submicron particles ( PM1 ) , and the proportion of PM1to PM10 was more than 90%. PM1was mainly composed of alkali metal chloride and sulfide, while PM1-10 was mainly composed of compounds formedby calcium magnesium silicate. Correlation analysis showed that there was a positive correlated between biomass ashcontent and PM1yield, while the content of Mg +Ca and n ( Mg +Ca) / n ( Si) were linearly correlated with PM1-10 yield.
