Effects of space heating on the pollutant emission ...

May 15 2020 · The results for coal-fired boilers show that the pollutant emission concentration is generally higher for small coal-fired boilers below 20 t/h due to limitations of the desulfurization equipment . SO 2 emission per unit of flue gas from a small boiler can be 2 to 3 times larger than that in a large coal-fired boiler above 80 t/h and soot emission can be 8 to 10 times larger.
