A STUDY OF CORROSION IN BALANCED FLUES - dgc

Fouling and blockage of the flue do not constitute any big safety hazard if it is a balanced flue in concentric pipes. If these types of flue get blocked the boiler's air-flow failure device will cut off the boiler. If the flue pipe gets perforated the flue gas will be recirculated to the combustion air; this will in

Feb 15, 2002 · The constant addition of make-up water to a boiler loop can result in scale and fouling. Pipes and fittings should be adequately sized for the required system flow. Velocities more than 5 feet per second cause system noise which can radiate throughout the building, while flow rates more than 8 feet per second result in system leaks due to erosion damage.
