ABSTRACT:
A landfill gas vent flare is provided which includes a flarehead disposed in communication with a landfill gas vent wherein landfill gas is permitted to flow therethrough. A spark plug is located on the flarehead and is electrically connected to a solar powered ignitor which provides electrical impulses to the spark plug at regular predetermined intervals to generate a spark every 1.5 seconds to ignite the landfill gas and ensure the landfill gas burns continuously. The sparks are continuously generated regardless of the presence of landfill gas or flame in the flarehead. The flarehead comprises an inverted, modified frusto-conical structure and includes a plurality of inlets which permit air to enter the flarehead and mix with the landfill gas to facilitate combustion and to further ensure continuous burning of the gas.
