Taking mixed coal composed of lean coal and anthracitic coal commonly used in power plants of Shandong Province as coal sort to be tested

the burnaway of said mixed coal

as well as releasing behavior of SO2 and H2S gases along the furnace have been studied on onedimensional pulverized coal firing test stand. Test shows that the sulfur educing behavior is closely related to coal quality and burning behavior of each single coal sort and the mixed ratio of single coal sorts. Along with variation of the coal quality and the mixed ratio

concentration of SO2 to be basically between two single coal sorts

but the regularity of H2S educing to be comparatively complex.
