Biogas flares have the task of temporary or periodic burning the biogas produced by biogas plants or landfills where there is no possibility to use it for energy production. Burning system is composed of a flare burner and a flare substructure. Flare is designed according to the principle of an injection burner and consists of a nozzle, an injector with an air flow regulation, a flame protection tube, a fitting group and a flare control system. The system for biogas burning is made of stainless steel. The flare substructure bears the flare burner and takes up the vertically installed fitting group. The control system is installed in a cabinet, which is mounted on a bearing structure of the burning system and contains the whole control system for the flame monitoring and the ignition of the flare.
