[Stoves] Fuel qualities as the limiting factor, and getting rid of WBT (Was: Frank on helium surrogate)

[Frank Shields]

The water test must NOT ‘Go’. It is just a test procedure that needs modification FOR THE PURPOSE of what we want to interpret the results. It is the only test I have seen where we start with the FUEL and end with a completed COOKING TASK. Starting with the fuel and ending with a completed task is a MUST. 

Thanks

Frank

I believe its the preparation of the gases before entering the secondary thats most important and thinking we might be able to make adjustments if we can learn the mix that burned hot and clean. I’m thinking the helium surrogate thats bled in with the primary air at a very controlled and constant rate will be very useful when monitoring the gases entering the secondary. I’m sure someone must have tried this. Perhaps Tom Reed or Jim Jetter?
