Re: Burning corn as fuel?

I did some experiments with the idea over the weekend and the results were for the most part disappointing. I lit the fire with wood and slowly started to add the corn. At first it caught quite quickly and gave a lot of heat, however as the wood burned away the fire died down considerably. My best e...

Burning corn as fuel?

Okay, I know it sounds ridiculous but corn has been used for a long time as fuel in pellet stoves. It doesn't burn as cleanly as wood, but it comes pre-pelletized, has ~7000 BTUs per lb, and, at least here in Oklahoma, can be had for abut 8-9¢ per pound at the moment, and is available throughout the...

Pressure Washer Pumps for Feedwater

Howdy

Has anyone had any experience using pressure washer pumps as a feedwater pump? It seems like an inexpensive solution, but I'd love to hear if anyone else has experimented with it.

Re: steamboat Emerald

I will be calling him today. As far as cunifer/kunifer/and whatever else they call it. I've quite some trouble finding many suppliers in North America as well, though there seems to be more than just a few years ago. Here are a few: http://www.fedhillusa.com/ http://www.farmerscopper.com/copper-nic...

Re: Desuperheater question

Tom, "Out of curiosity, where can you access a copy of the ASME BPVC" You can buy it from the ASME, I think for a couple of thousand dollars for the whole set. The engineering firm I worked for (45 years so far) is certified to make unfired pressure vessels and boilers, and thus has full sets of AS...

Re: Desuperheater question

Adding a couple of points to Bart's list, needed to comply with the ASME Boiler and Pressure Vessel Code: No. 6 Boiler check valve, followed by an Isolation Valve If the economizer can be isolated and bypassed, then the economizer itself requires pressure relief protection because it then becomes a...

Re: Desuperheater question

Trying to wrap my head around the concept a little bit. First, why use a steam coil instead of a water coil? If you're worried about burning out the coil, water would transfer heat away faster, and should prolong service life. It would also make one hell of an economizer, especially if steam product...

This (if it shows ok) is one I have designed.
That's a really clever and fascinating design. How do you anticipate dealing with condensation in the crankcase?

Re: Boiler feed pump ?

Ian, I've been giving a lot of thought to this lately as I re (x4) design my engine. Given the general difficulty in sourcing a feedwater pump, it doesn't seem that constructing one should be extremely difficult by comparison. A single-acting pump should be able to work with some heavy steel flanged...
