Abstract
An improved apparatus for monitoring and controlling the composition of a flammable gas mixture to prevent accumulation of explosive gas mixtures in a substantially closed container. The apparatus includes a combustion chamber through which a sample stream of gas mixture is propelled. In operating the apparatus, the mixture within the combustion chamber is subjected to a series of high voltage ignition charges by means of an automotive spark plug which receives ignition charges from a conventional automotive capacitor discharge ignition system power unit and automotive ignition coil with the ignition charges being triggered by an electrically powered oscillator at a frequency preferably between 10 and 20 Hz. The electrical components and combustion chamber are housed within an explosion proof housing. A temperature responsive switch within the combustion chamber causes the actuation of solenoid operated pneumatic valves to provide continuing visual indication of the status of the system and provide injection of non-combustion-supporting gas into the closed container to prevent accumulation of explosive mixtures therein.
