Abstract
A working machine for use in milling the surface of a road includes a drive engine that produces engine exhaust gases. The working machine also includes a milling drum that is mounted for rotation against the surface of the road so as to generate milled material including dust from the road surface. The milling drum is contained within a milling chamber, and a spray assembly directs water into the milling chamber in such a manner that, during a period of rotation of the milling drum against the surface of the road, at least a portion of the water is converted to a vapor. A conduit is provided for conducting at least a portion of the engine exhaust gases into an enclosed space in communication with the milling chamber to raise the temperature of a gas stream therein containing vapor and dust from the milled material.
