Optimized combustion with air supplied through over-fired air ports located above the top burners is how this is achieved. There may be very limited straight run available between the windbox and the overfire air ports. WebA technique to stage combustion is done by installing secondary and even tertiary overfire air (OFA) ports above the main combustion zone.
