METHOD AND APPARATUS FOR NON-POLLUTING COMBUSTION OF WASTE GASES

摘要

A non-polluting waste-gas disposal system for processing plants or other operation subject to variable quantities of waste gas for disposal. The system includes a low-level burner normally adapted to handle the usual volumes of plant waste gas, required to be disposed, without visible flame, smoke or noise pollution. An elevated flare can be used in combination to consume gases in excess of the normal capacity of the low-level flare. The burner utilized within the low-level flare includes a coaxial air baffle plate positioned forward of a gas conduit. The plate has a plurality of perforations for the passage of combustion supporting air. An opening around the nozzle has a cross-sect-ional area of not more than 90% of the discharge area. Pressure of flow conditions of the waste gas are sensed such that increases thereof are supplied to additional burners proportional to the quantity of waste gas to be burned and to provide optimum burning conditions.
