Abstract

Process for local destruction of compact material, e.g. clinker coating, masonry remains, etc., in hot thermal systems such as heat exchangers, industrial ovens, furnaces, and metallurgical melting vessels, uses an explosive (5) arranged on the front end of a lance (3) in a cooling container (1) through which coolant (4) flows. The explosive is inserted through an opening in the hot thermal system directly adjacent to the material to be destroyed by holding and moving the rear end of the lance and is ignited by an ignition device. The coolant flows into the cooling container designed as a double tube having a cooling head (10) and a supply head (11) over the lance into the supply head, through the inner tube/inner cooling casing (27) to the front end of the cooling head, past the explosive container (25), between the inner cooling casing and the cooling head housing (23) back to the supply head, and from this out of the hot thermal system. An Independent claim is also included for a device for carrying out the above process.
