Burning of biogas is realized by closed flame, which means that flame is entirely covered by chimney and can’t be visible from the outside of flare. Air inlet can be regulated manually or automatically, depending on flame temperature. Due to low calorific value of biogas (25-45% of CH4) every 2ls type flare is equipped with additional propane burner, supplied from the gas bottle. Temperature of biogas burning in this type of flare does not exceed 1 250 oC (set temperature)
Flare structure consists of following elements:
All construction elements of biogas flare are made of stainless steel.
