Why Oxygen Levels Matter in High Efficiency Boilers

Oct 10 2017 · The boiler will operate in condensing mode at highest efficiency more of the time. There is a diminishing returns effect in oxygen content and performance for the unit. Too much available oxygen will lead to inefficient combustion. Over time the unit will require unscheduled maintenance.

Oxygen attack in boilers - Lenntech

Oxygen is highly corrosive when present in hot water. Even small concentrations can cause serious problems: iron oxide generated by the corrosion can produce iron deposits in the boiler. Oxygen corrosion may be highly localized or may cover an extensive area. Oxygen attack is an electrochemical process that can be described by the following reactions:

Boiler Combustion | CleanBoiler.org

Excess Air. A boilers 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.

Technical advice on boiler combustion control

The flue-gas temperature of a typical boiler could be anywhere in the range of 300 to 500 degrees Fahrenheit range. As a result the extra oxygen could have entered the boiler at 70 degrees F and exit at 400 F. The extra oxygen reached this temperature by receiving fuel energy in other words fuel was purchased to heat the extra oxygen.

High Pressure Boiler: What is it? Types & Characteristics

The Velox boiler is a forced circulation water tube boiler that uses high velocity to rapidly produce steam. The principle of the Velox boiler is built on the velocity of the gas which moves faster than the speed of sound and increases the rate of heat transfer.
