Re:L-H Intake Temp |
Hi Bill,
on the 98% humidity vid you could see a central conical shaped blue flame tip emerging from the small intake. obviously with an inverse shaped cone of cool air flowing in around it. The intake would be generally cool enough to touch quickly, but I wouldnt want to grasp it without a few precautionary pokes.
Heat soak would be your worst enemy on a regular basis, but a massive heat release (end of vid) would maybe melt most composite materials of the fibre/ kevlar type? I aint no expert.
Sadly I cant even give you a rough idea with my digital multimeter. A mate and I burnt the end off the K type thermoprobe testing the wood fired 18 gallon beer keg years ago. It hit 1095 deg C before it failed, not too bad we thought.
It was an interesting shed heater. when it had a side port flue , 90 deg bend then 8 feet of up pipe (all common guttering stuff) it ran real hard. If you got it red hot around the base by burning Mallee of Gidgee etc and slammed the front door shut it would shuffle around on the concrete floor and chuff furiously. That was long before we ever heard of Karmen sheet vortex layers.
Like most things, mate and I modified it to try and make it better. We added a top, central flue running thru a nifty butterfly regulator we made with genuine local timber handle and a spring loaded marble to hold the butterfly in one of six positions. You guessed it, it never performed half as good.
For the record, we never drank the contents of the keg. Rick was a never ending spring of home brew draught beer and a potent but magnifique alcholic apple cider.
