Aiming at the request of improving energy availability and reducing shoot pollution, clean burning technological research of gun propellant and charge is summarized. Primary source of shoot pollution and the important significances of clean burning technological research of gun propellant and charge have been analysised. It is considered that two primary source of shoot pollution are irrationalities of gun propellant design and charge design. The feasible approaches of realizing gun propellant and charge clean burning have been summarized, they are optimizing design-balance of propellant prescription, designing high progressive propellant, improving reasonable propellant charge structure, adopting new low-pollution materials, etc., and integrating those methods will obtain better effect. It is suggested that clean burning technology should be emphasized in the relevant research in the future.
