Experimental on the characteristics of sulfurous pollutant with different blended coals

In order to reduce the sulfurous polltant which was procreated by burning the high-sulfur lean coal,the low-sulfur lean coal and low-sulfur bituminous coal were separately mixed into the high-sulfur lean coal.The characteristic of sulfur release in different blended coals was studied by the one-dimensional combustion experimental system.The results showed that the characteristic of SO_2 release in the lean blended coals was not affected by each coal,the disciplinarian of H_2S release was complicated;velocity of SO_2 release became fast in the lean-bituminous blended coals with the bituminous coal being mixed into.
