Hello Guys.

I'm new here, but I thought I'd share a couple of problems I once had when manually starting a turbine when it was cold & frosty, about -1'C.

Especially if you manually start your turbine with air & propane:

Starting rpm too low:
Make sure the air regulator on your scuba bottle works at low temp. Mine is for operation >= 10'C, below that it doesn't regulate properly and gives low flow/pressure.

Combustion chamber pre-warm not getting hot enough:
Keep your propane bottle warm,otherwise the vapour pressure will be too low. (e.g stick it down your pants etc, not inverted or you might get a wet start !)

But please don't use forced heating on your air/propane bottles.

My humble tuppany's worth.
