# ﻿how to measure the boiler flue gas oxygen content

### CHAPTER 3 COMBUSTION CALCULATION

Equally, Oxygen (O2) levels should be in the region of 3-5% for gas appliances and 5 - 8% for oil & solid fuel appliances - Any other levels suggests an inefficient use of energy,wasting fuel and money, or a potentially unsafe situation where too much CO is created through oxygen deficiency. Flue Temperatures for gas appliances should be less than 200 degrees centigrade or less than 300 degrees centigrade

### Flue gas carbon dioxide and oxygen - Ian Braithwaite, BSc

Oxygen: 100 x 5/92 = 5.4% . So, my flue gas analyser would actually measure 5.4% oxygen and display this and 8.7% carbon dioxide. No more calculations will be done here: an exercise for the enthusiastic student is to put the numbers into a spreadsheet and produce a graph like the one shown here. Modern boilers have their combustion settings adjusted for particular values of carbon dioxide.

### Measurement of Oxygen Concentration in Package Boiler Flue

Optimizing air intake for boiler operation requires continuous measurement of the oxygen concentration in the flue gas. 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.

### Measurement of Oxygen Concentration in Package Boiler Flue

This Oxygen concentration and humidity at high temperatures consists of a ZR22G detector equipped with a long-life and highly reliable zirconia sensor, and a converter ZR802G equipped with digital communication and data log functions. ZR22G and ZR802G can be measured directly and continuously without a sampling device.

Boiler flue condense and sensor light | DIYnot Forums. Sep 03 2019 · If the latter then the boiler's efficiency may have changed resulting in hotter flue gases than when it was installed and a service check on the boiler may be needed If you need the lamp to be where it is then fit a remote PIR sensor that covers the area but cannot see eithe the flue or the lamp.
