Flares from LFG Technologies represents state-of-the-art in enclosed flare systems with ultra low emission levels. We are so excited about these new flare systems we no longer build standard enclosed flares. We hope as demand continues to increase and prices drop to stop building utility flares. We are almost there now!

Emissions are controlled with the burner system and precise control of air mixed with the gas in a premix chamber. The air blower is controlled with a VFD and we recommend control of the gas blower with VFD also. Flare interface is with a touch-screen. HTF 5.0 (High Temperature Flare).

LFG Tech supplies the complete package to include the flare, blower package, VFD’s and control panel. You have only one supplier to deal with.

Flare components to consider:

Data Logger

Data management is a major part of New Source Performance Standards and must be taken into consideration when choosing flare instrumentation. Ideally, the flare and control panel should do all the work. With our flares, that is exactly what happens. Data is easily downloaded to an excel spreadsheet and NSPS reports can be put together in hours, not days. Paperless Chart Recorder with PC Card or hard-drive back up. More accurate and reliable than pen-style. Include both flow and flare temp with up to 12 channels for input.

Touch Screen Interface

Highly reliable in all weather conditions. Allows for flexible control schematics for flare and auxiliary systems.

Flow Meters

Hot wire, thermal mass, orifice plate.


Omega autodailer with up to 8 inputs. Programmable from a cell or touchtone phone.

Knockout Pots

Coated carbon or stainless steel. Provides extra protection for blower system.

Variable Frequency Drives (VFD’s)

Provides precise control for vacuum. NEMA 4 cabinet with air conditioning for long life.


Aerovent or National Turbine blowers. Up to two year warranty on some blower systems.
