MethaNull

• Status quo 2014:

∑(energy from flared gas worldwide) ≈1/3 of the annual EU needs in natural gas

• Landfill gas: when CH4 contents < 20% vol – Pilot gas flame with natural gas

– High conventional fuel costs

• The MethaNull technology: a burner concept that consumes less support fuel

• CBOne‘s pulsator can be externally assembled on industrial burners • This method extends their operation range and reduces their consumption • picture: historical prototype, and commercial version

Example of use: extension
