Waste fuel burners are designed individually according to each customers’ needs. All relevant conditions at the customer's facility for the burner equipment are evaluated thoroughly in terms of waste properties, burner capacity, process issues, and emission requirements.

Concentrated NCG (CNCG) burners are widely used in recovery boilers and in dedicated fire-tube boilers to incinerate odorous gases and liquid methanol from pulp mills.

CNCG incinerators (flares/oxidizers) are used in pulp mills for back-up use to verify non-odorous operation in emergency situations in pulp mills.

Petrochemical incinerators (flares/oxidizers) are used in various types of oil and chemical terminals to verify non-odorous and safe operation in loading and unloading of tanks.
