[Stoves] continuous flow steam injector

[Craig Gallien]

Thanks for that Nickey,
The problem with a non return valve is the the steam pressure has to drop 
below the water pressure for the valve to open , so I would get surges of 
steam instead of a continious flow . Thats the effect I get now.

I think a non return value would be an improvment by not allowing steam to 
escape up the supply line but it can't allow me to maintain a continuious 
pressure in the boiling chamber.

>From a safety point of view , if the jet gets blocked the steam has no 
escape I may get a destructive pressure build up down stream from the non 
return valve.

Thanks for you ideas
Craig
