burning needs excess air in packaged boiler

Continuing a time-honoured tradition - nibe.eu

Burning Boiler Works: In a NIBE wood burning boiler, there are two air intakes, primary and secondary, which provide the oxygen needed for the wood to burn. The primary intake acts as the main oxygen source, driving the burn-ing process; the secondary intake allows for fine tuning of the burn-ing process and enables cleaner emissions.

Excess Air. A boiler's excess air supply provides for safe operation above stoichiometric conditions. A typical burner is usually set up with 10-20% excess air (2-4% O2). NOx controls that require higher excess air levels can result in fuel being used to heat the air rather than transferring it to usable energy.
