ABSTRACT:
Apparatus for smoke suppression in the burning of waste gases in flare stack, comprising a conduit means through which waste gases are flowed, under pressure, to a flare stack; a source of hot water in the range of 200.degree. to 250.degree. F. in temperature, or higher, and a plurality of spray nozzles for spraying the hot water, in the form of cones of fine droplets of water, which by their high velocity thoroughly mix with the flowing waste gas, and provide a water vapor content mixed with the waste gases in the range of at least 6% mole percent, or more. Means are provided for control of the rate of flow of hot water dependent on the temperature of the water and dependent upon, at least, the mass flow rate of waste gases to the flare.
