Effect of the mineral fraction in waste on the amount of gaseous compounds of sulfur, chlorine, and fluorine in flue gases

Abstract

The distribution of solid and gaseous compounds of sulfur, chlorine, and fluorine along the boiler loop in thermal power plants fuelled mainly by municipal solid waste is studied. The yield of gaseous compounds of sulfur, chlorine, and fluorine is found to depend on the composition of the mineral fraction of the waste, as well as on their initial content in the waste. Because of the calcium, potassium, and sodium contained in the mineral fraction, almost all of the sulfur, 20 – 26% of the chlorine, and 27 – 29% of the fluorine are chemically fixed.
