What it is: NOx is a generic term for the chemical compounds made of nitrogen and oxygen. The air we breathe and use for combustion is 20.9% oxygen (O2); 79% nitrogen; and .1% other. In the combustion process, some of the nitrogen and oxygen in the air combine to create NOx. The higher the temperature, the more created.

CHAPTER 3 COMBUSTION CALCULATION

Flue Gas Analyzers The percentage of oxygen in the flue gas can be measured by inexpensive gas-absorbing test kits. More expensive (ranging in cost from $500 to $1,000) hand-held, computer-based analyzers display percent oxygen, stack gas temperature, and boiler efficiency. They are a

Improve Your Boiler's Combustion Efficiency

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.

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.
