Abstract
A pilot gas conservation system for flare stacks is provided in which the activation and control of the pilot gas burners is determined by the wind conditions so that if no flare gas is flowing the pilot burners are shut down and with moderate and minor wind conditions the supply of pilot gas is maintained at a lower level than that required for higher wind velocities. A flow responsive switch is provided to determine the flow of waste combustible gas to the stack so that, if required, the effect of the wind speed determines the pilot gas flow.
Claims10
A control system for the pilot gas for a waste combustible gas flare burner having a pilot burner which comprises;
- a waste combustible gas flare burner,
- a connection to a supply of pilot gas,
- a pilot burner for said flare burner connected to said supply connection igniting means for said pilot burner,
- control means for controlling the supply of pilot gas to said pilot burner comprising a wind speed responsive member contiguous to the flare gas burner and a pilot gas control valve means,
- control means for said igniting means comprising a member responsive to operation of said pilot burner.
