AirScience Biogas Flares

Anaerobic Digester (AD) biogas applications


For AD biogas applications enclosed flame flares are used to burn excess biogas from the process as well as to burn the full biogas production while the downstream biogas valorization system is stopped for maintenance or emergency conditions.

The exhaust gas emissions meet the most stringent North American environmental requirements. This is achieved with combustion temperatures between 1000C and 1200C. The patented high mix, low NOx burner provides the lowest NOx emissions available on the market.


Simple Installation, High Satisfaction


The combustion performance is automatically regulated by a PLC control system with optimum combustion temperature and gas mix. All controls are integrated in a weather proof NEMA4 cabinet.


The AST-EFF flare is self-contained and pre-mounted on a structural steel skid as well as pre-wired and pre-piped for easy installation and start-up.


North American Standards (CSA-UL)


All the components of the AST-EFF enclosed flame flare are CSA and UL approved and the complete flare system receives a CSA inspection after installation at the site and the corresponding certificate. 


AirScience Technologies was founded in 1993 from the merger of two companies, Canadian and American. After fifteen years of designing and building air pollution control systems for various industries, the company has refocused its activities on biogas purification and biogas flares.
