Investigations into the variability and control of dioxin formation and emissions from coastal power boilers

Stack dioxin emissions from power boilers burning salt-laden hog fuel in British Columbia have decreased by over 68% since 1995, from 10.5 grams of NATO TEQ per year in 1995 to 3.3 - 3.4 grams of TEQ in both 2001 and 2002. These reductions have been realized through capital expenditures, boiler shutdowns, and ongoing efforts to improve power boiler combustion efficiency and decrease particulate emissions. However, the large variations in …
