The Steamboating Forum

Hi Deitrich,

How much vacuum do you anticipate from these pumps? As best I can tell from Google, they seem to max out at about 12" of vacuum. Are you making any modifications to increase the vacuum, or is the intent just to pull enough vacuum to clear the condensate?

Cheers,
Scott

Hi Kelly and Bart, Thank you both for the feedback. It's that 6.1" number I was wondering about - that gives me a great reference to work with. Bart, my intention was try firing on hardwood wood chips or homemade charcoal. My goal is to have the boiler be large enough that it can supply adequat...

I am looking for guidance for how much firespace is required for very small solid fueled boilers. I am putting together a power plant for a canoe, where weight and center of gravity are obviously critical. I am thinking of very small roberts, express, or 2-drum type boiler, with a 4" steam drum...

It's time to sell the tug. I bought this boat - the "Spirit of Algoma" in 2009 after chancing across her in a Milwaukee boatyard. The boat was not in running condition then, but had been run in the prior 5 years (presumaby by someone attempting suicide by boiler). I removed and scrapped th...

That is an elegant boat. Can't wait to see you get it back on the water!

Welcome Peter! I probably speak for almost everyone on the forum in saying we'd love to see and hear about your build.

Cheers!

Hi Pete and Bart, I am also considering a similar overfeed/underfeed with accumulator plan. I was thinking of a more analog system with a double-acting feed pump where one side of the feed pump would always feed the coil, but the other side would have a bypass controlled by a stanley type or similar...

Hi Pete, Sounds wonderful! Will Lamont boilers and the like be allowed on the site as fellow travellers? I have a hot water pressure washer coil I had made with the intention of running my 20' boat with it. If I every have a minute to make some progress on the d**n thing I'd love to share it with th...

I think I have all the issues from Ron's editorship. I'll see if I can find that one and make a digital copy this weekend.

Cheers,

Thanks for sharing the video! What pressure were you running at? Were you happy with the performance of the pump?

Cheers,
Scott
