A system for supplying purge gas to a flare system depending upon the temperature and the pressure in the flare to control the flow, of purge gas through the flare during the period when flaring of gas is discontinued. The rate of flow of purge gas is determined by temperature measuring means. However, the control of flow depends upon the pressure in the flare as well as the temperature so that when gas is being flared and the temperature is high and the pressure is above normal the purge gas is cut off, whereas when the temperature is high and the pressure is normal the purge gas is flowed.
