In this full-scale mill study we measured flue gas chemistry and especially submicron size dust (fume), which follows the gas streams up to the electrostatic precipitators. The purpose of these studies was to shed new light on the formation mechanism of fume and gaseous emissions (NOx) in recovery boilers, Especially interest was aimed at the relative importance of the fume as produced from the burning black liquor droplets versus the one volatilized from the char bed. For the first time in this study quantitative online data are available on particulate formation during char bed burning, as the liquor spraying was totally interrupted for a few minutes in these boilers.
