Abstract
A biogas flare system for burning biogas generated primarily by a landfill includes at least one burner for igniting a mixture of biogas and air. A main supply line supplies a mixture of biogas and air to the burner. A biogas supply line feeds biogas into the main supply line. An air supply line feeds air into the main supply line. A mixer structure mixes the biogas and air prior to the mixture being supplied to the burner.
Claims4
An ignition arrangement for a plurality of burners in a biogas flare, each burner having a tip from which a flame extends, the arrangement comprising:
- at least one enclosure surrounding one of the burners and extending upwardly from the burner tip, said enclosure having an open top and an inner surface exposed to flame generated from the burner;
- a pilot for igniting the burner surrounded by said enclosure;
- an ignition port extending from the burner surrounded by said enclosure to an adjacent burner, such that when said pilot lights said enclosed burner, combustion gases from such burner travel through said ignition port to ignite the adjacent burner.
