Emissions of Pollutants from Burning Petroleum Coke and Oil Shale Mixture in Fluidized Beds

This paper analyzes the data of pollutant emissions from burning mixtures of petroleum coke and oil shale at different ratios in a 1 MW CFB test burner. Results show that petroleum coke containing over 6% sulfur(mass fraction) can be used as fuel resource if mixed with oil shale at an appropriate ratio to reduce the mixture's sulfur level to less than 3%. With suitable Ca/S molar ratio and boiler bed temperature, the pollutant emissions from burning the mixed fuel can fully meet the national standards of environmental protection.
