ABSTRACT:
A variable-split blowdown coal feed system supplies two streams of air entrained pulverized coal in a uniform, well-metered steady state manner. Splitter dampers control a split of a coal and air mixture into two streams which are fed to respective cyclones operated in the blowdown mode. The cyclone's exhausts are connected in common to a manifold through which a blowdown damper controls the air-to-coal ratio in the air entrained pulverized coal streams that are expressed from each cyclone's discharge.
