Emission limits of (typically) 200-300 ppm for Sox and 100-150 ppm for Nox can usually be met without resorting to post treatment of flue gas. ASH / CARBON / SAND / LIMESTONE The carbon content of the bed is typically around 2-3 percent (as coal being 5% of the total bed material) and the balance of the bed meterial can be ash, sulphated limestone or sand.
Ang hangganan ng emisyon na 200-300 ppm para sa SOX at 100-150 ppm para sa NOX ay madalas nakakamit ng hindi gumagamit ng panlunas sa “flue” gas. ABO / KARBON / BUHANGIN / LIMESTONE Ang nilalamang karbon ng palaparan ay humigit-kumulang 2-3 porsyento (basta’s ang coal ay 5% ng kabuuang material) at ang balance ng materyal ng palaparan ay maaaring maging abo, sulphated limestone at buhangin.
