in Gas Heating
Hello,
Would some of you folks who have Combustion Analyzers be willing to post what gases they measure, what the range of values they measure, and what functions they execute with the info they collect. Also, would it be possible to leave a combustion analyzer in place as a permanent addition to a heating setup.
I'm gathering they have a probe which is inserted inline in the exhaust gas flow, (chimney/flue) etc. Are there any other points at which the analyzer does its analysis? (do they analyze air intake?)
I'm basically wondering whether its possible to build one and how much it would cost.
How are they calibrated? Do you use reference samples?

What's in a Combustion Analyzer? What does it measure?
Would it be enough to measure O2, CO2, CO, and (which? all?) of the following..
"Natural Gas"
LPG and propane
butane
methane
H2
Alcohol
Then what kind of number crunching/display needs to be done?
Thank you!0 -
If you go online
to the various websites of the folks who make these you will get all the info you are asking for.
Bacharach, Testo, Wohler, UEI, E Instruments, TSI are just some of the manufacturers.
These all use a probe which must be placed in the flue connection of the appliances. The probes include a thermocouple type sensor inside the probe for measuring flue gas temp.
The testers can be set for measuring
Natural gas (methane)
Propane (LP)
Butane
#2 oil
#6 oil
These testers are designed to measure flue gases and analyze them and give readings such as
O2,
Flue Temp,
Carbon Monoxide diluted
Carbon Monoxide air free (actual CO)
CO2 which is actually not directly measured with a sensor but is a calculated reading done by the meter electronics.
Efficiency same thing it is a calculated reading
Draft in inches water column typically
Some testers also measure nitrous oxide
There are some very expensive instruments that are also available which are typically used on some commercial and industrial applications.0
