MEDIUM TEMPERATURE FLARES

Biogas flare
Biogas is formed naturally from organic material. Anaerobic digestion is an ideal alternative for organic waste treatment and production of energy.

Biogas, after proper treatment, can be converted into electricity in engines and it can be upgraded to biomethane at the place where it is produced. Biogas technology is the conversion of organic substances to methane as fuel and to valuable fertilizer from available resources that otherwise would go unused.

Gastechnik AG designs and manufactures a wide range of systems for proper treatment and utilization of biogas.

Medium temperature flares are burning systems that operates at lower temperatures than the high temperature flares. Basically the flare represent an economic and affordable solution for those situations in which the gas does not contains traces of hazardous gases. The end user complies with emission regulations without excessive investment and operating cost.

Because the flame is concealed in the combustion chamber is particularly useful for residential areas.

The typical situations in which a medium temperature flare is recommended are:

  • Excess of gas not used in power generation. In the moment in which the gas engine stops for any reason the gas is diverted to the flare. In this case the flare works some hours per year.
  • In combination with gas holders in biogas plants.
Concealed combustion with temperatures >850° C and a combustion efficiency >99%
