temperature measurement in a gas turbine combustor 1

[Bronwyn]

I would like to take temperature measurements in the primary zone of a reverse flow gas turbine combustor. The fuel being used is Paraffin. I am assuming that I need to use a method that can measure in excess of 2000K - Preferably 3000K. Any advice or suggestions of appropriate measuring equipment or techniques would be appreciated.

bronwyn;

Maybe a high temp thermocouple would do the job, you could do a web search for these.

There is a 900HT series miniature head thermocouple from

http://www.marshbellofram.com/tcp/catalog/high_temp.htm

that may be suitable.
If there is nothing available from there catalouge i'm sure they could tell you who to contact.

Hope this helps

OMEGA in Manchester UK makes very good and versatile range of high temperature thermocouples, U might want to pick a hand held Infrared Thermometer (iR2 SUPERMETER) or a Thermocouple with the probe elonagted by insulated thermocouple wire. Check them out on

Are you wanting to measure the combustor for a reference of flashback? We normal see type K thermocouple there. Type k measure up to 2300 DEG. F and only for a very short period of time. I believe there is one that will measure approx. 300 Deg. f more than type K and it has a melting point of 3190 DEG. F useful range is 0 to 2600 DEG. F. In the Combustion Turbines today they are equipped with DLN system and they are equipped to measure a an area of the basket and this is the flashback thermocouple area whick stick in the basket about 1/16 of inch.I don't know if there is any newer techknowledge that measure the actual flame temps in a combustion chamber with in a basket or can. We do measure Blade path temps and they two are Type K. They see normal temps of 1200 deg F continues.. This is only speaking of 70 to 300 MW combustion turbines which I have had the privileg to work with.. Note that Flashback is only a reference because when dealing with flashback you also take into affect the combustion shell pressure.
