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

Some other URL's with the same info are:
http://www.ironworking.com/burn.html (http://www.ironworking.com/burn.html)
and
http://www.torchcutter.com/fuelprop.htm (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 ;)
