A few seconds using a search engine turned up a web page with the answers you seek, courtesy of the US Army  

http://www.adtdl.army.mil/cgi-bin/atdl.dll/tc/9-237/Ch11.htm

Some other URL's with the same info are:

http://www.ironworking.com/burn.html

and

http://www.torchcutter.com/fuelprop.htm

You really need to take more initiative in finding out the answers to your questions; obviously Bernzomatic's site isn't the last word on torch temperatures
