Abstract:
1. An anti-explosion and fire arrester system for use with an internal combustion engine comprising: means coupling a duct to the engine for passing and processing the exhaust gases and fumes emitted by the engine; said duct having an enclosure with an input end for receiving the exhaust gas and fumes and having an output end for passing the exhaust gases and fumes processed within the duct; the duct enclosure forming a wall whose inner surface defines an opening through and along which the gas and fumes are contained and flow; a filter structure coated with a metal for enabling the oxidation of the gases and fumes securely mounted across the opening of the duct in a direction generally perpendicular to the flow of the gases and fumes; an insulator layer mounted about and along the outer surface of the wall of the duct; and a jacket for carrying a coolant mounted above and about the insulator layer whereby the temperature on the external side of the jacket, facing away from the duct, is less than a specified value while the insulator layer insulates the duct from the jacket to allow the temperature within the duct to have a value to enable oxidation of the gases and fumes to occur; and wherein the means coupling the duct to the engine includes a primary heat exchanger connected between the internal combustion engine and the input end of the duct and wherein the output end of the duct is connected to an additional heat exchanger and spark arrester; and wherein the additional heat exchanger is coupled to a still further dry cooling and spark arresting device; and wherein the additional heat exchanger and the still further dry cooling and spark arresting device are jacketed with a jacket for carrying a coolant to maintain the temperature on the external side of the jacket below said specified value.
