- 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.
