Re: condensing without a pump

From looking at various videos of the Kitchen rudder in operation it does seem like a marvellous device. Perhaps if he'd marketed it as a vector thrust steering device he'd have had more success. The partial shrouding of the propeller that it offers should mean it is more efficient too. The other da...

Re: condensing without a pump

That's their older design. The newer ones are enclosed, use a piston valve and have no reversing gear and the enclosed design makes it difficult to incorporate one, hence the interest in the kitchen rudder. They're principally sold into Africa and forested parts of Asia where the wood as a fuel is r...

Re: condensing without a pump

Thanks for that. That's just what I was hoping. I think we're both paid up members of the keep it simple brigade ;)
Further to which I'm fascinated by the discussion re Mr Kitchen's rudder. Looks like you could junk all the reversing gear too and just run a single with a water pump. Mmmmm....

condensing without a pump

I have read on here that it is possible to run a keel condenser without a pump, relying on exhaust pressure to return the condensate to the hotwell. How well does this work in practise? It seems like a reasonable approach if running a single, say a 3 x 4, where vacuum isn't as important as on a comp...

Re: Durham Donkey Boiler

Nice drawing, Fred. I would build it with a water leg. Except for the firebox penetration there are no drawbacks that come to mind and the steam producing area of the boiler are so much improved. just two rings and the firebox hole and you easily double the area that receives radiant heat from the ...
