Zeeco Biogas & Landfill Flares

Biogas flare systems are used to dispose of gases that are produced from decomposition of organic matter or biomass. Typical examples are gases produced from landfills, wastewater treatment (anaerobic digesters), or other biomass sources.

Gases are typically mixtures of methane, carbon dioxide, small amounts of nitrogen, oxygen, hydrogen sulfide, and others. Biogas must be handled in a specific manner to ensure combustion to a high degree of efficiency. In addition, the possibility of oxygen in the gas mixture coming to the flare means flame arrestors and special flame arresting burners must be employed. Biogas can be burned to a high degree of efficiency in either an elevated flare or an enclosed ground flare system.

If your facility is an environmentally sensitive area where NOx emissions are tightly regulated, such as one of the EPA’s 8-hour ozone Nonattainment areas, then you will also need an ultra-NOx VCU.  Zeeco has developed the TriClean VCU, which is an ultra-low emission VCU that can achieve NOx emission of less than or equal to 15 ppm (0.018 MMBTU/hr.) and CO emissions of less than 10 ppm (0.01 MMBTU/hr.).
