determining flame temperatures	zr2yz125	2/19/2010
I have situation where I have to take a natural gas burner (20k BTU/hr) and run it on a different gas (99.99% UHP Methane). The test results from the overall system are different than calculated so I would like to measure the actual temperature of the flame cone produced at the burner port. Bottom line - I am trying to determine a good way to measure the temperature of a flame. I thought about putting a small piece of metal in front of the flame for a controlled amount of time and measure that... I have a P65 with the High Temperature option.

You have to find the flame emissivity first. There are some research about similar flames: flame emissivity = 1 / 1+(C/D) D= pool diameter, C=constant For more information please read the article: "Determination of Flame Emissivity in Hydrocarbon Pool Fires Using Infrared Thermography". http://www.springerlink.com/content/q478424q78m68005/ Kind regards, -- Ramiro Álvarez Clavero Remote Sensing Service http://webs.uvigo.es/ramiro Center for Support of Scientific and Technological Research Vigo University
