Abstract
In a flare system for waste gases, apparatus is provided for controlling the flow of purge gas into the flare gas line, as required, and not on a continuing basis. Sensor means are provided for detecting a change in temperature in the flare gas line, and means are provided for controlling the flow of purge gas whenever the temperature in the flare gas line changes to a lower value. No purge gas flow is required when the temperature is constant or when the temperature is rising.
