ABSTRACT:
A bed of high-sulfur coal is burned in transit through a furnace on a horizontal or inclined travelling grate. Low pressure air is fed upwardly through the bed in quantities sufficient to react with most of the carbon content of the coal, from which sulfureous gases arise. High pressure air is blasted upwardly through the remnants of the burning coal as they fall off the end of the grate run. Clinker content of the residue free-falls off the end of the grate run into a collector while burned or partly burned fines are elevated above the end of the grate run. High pressure air with entrained limestone blows the elevated particles back through the sulfureous atmosphere above the bed so as to react with the carbon content of the particles and grab the sulfur.
