Espedal, M L

Burner for use in a coal gasification process wherein a combustible mixture is formed comprising a combustion supporting gas such as oxygen, and a coal slurry. To avoid deposition of slag and ash particles along the hot, exposed face of the burner, a dynamic fluid blanket or barrier is directed transversely to the burner face. The fluid flow originates at the burner periphery and is addressed to sweep, or impinge against at least a part of the burner face adjacent to the central opening which defines the burner discharge port.
