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.

Oxygen Control | CleanBoiler.org

For Example: 4.5% Excess Oxygen reduced to 2.0%. 1.0 (0.7972 / 0.8308) = 0.04044 = 4.04%. NOTE: Because some boilers operate with a very high percentage of excess oxygen it is common for the first year savings to be substantially higher than this.

Tips for combustion analysis of commercial boilers | 2016 ...

Most boilers are designed to supply between 12 and 15 parts of air for each part of gas. Some industrial facilities can reduce the air-to-fuel ratio even lower than 20% by using an oxygen or O2 trim system. This system uses a sensor in the flue to monitor oxygen content while the burner is running and constantly adjusts the air-to-fuel ratio.

Zirconia Oxygen Gas Analyzers - COSA ZFK - Products - COSA ...

The ZFK is designed for oil or gas fired operations with stack gas temperatures up to 1150ºF. This probe uses the natural pressure drop created from stack gas passing across the prove tip to deflect the sample gas past the oxygen detector for measurement. The detector detaches from the probe for service without removing the prove from the stack.

Measurement of Oxygen Concentration in Package Boiler Flue ...

The typical package boiler is a water tube boiler or flue and smoke tube boiler with a capacity of 5 to 20 t/h (average steam generation capacity). The most widely used fuels are heavy oil light oil kerosene and gas. The ZR22G/ZR802G zirconia oxygen analyzer is ideally suited for package boilers thanks to its long service life and low maintenance and is an effective tool for the reduction of fuel and electric power
