Mill recirculation system
A mill recirculation system includes pulverizer means classifier means and burner means as well as a preestablished fluid flow path by which the pulverizer means and the classifier means are interconnected in fluid flow relation with the burner means. In accord with the mode of operation thereof, a separation is had at the classifier means of the stream of the gaseous medium such that a portion of the gaseous medium is recirculated along with the oversize solid fuel particles back to the pulverizer means while the remainder of the gaseous medium is operative to convey the solid fuel particles that are of the desired size from the classifier means to the burner means for burning, i.e., firing, in the latter.
