Re: Infrared Burner for LSR Boiler - 5 days ago
Rick About thirty years ago we experimented with radiant burners both ceramic and porous and wire screen. The problem was they were limited more or less to a fixed amount of fuel. Not quite enough for the space they took up. Rollyby Rolly - SteamStuff
Re: Force circulation steam generator design - 4 weeks ago
Ken As I do some real issues. Supercritical steam 3,208 psi 705 F The best steam cylinder oil will not hold up at that temperature. I have read that PTFE will work up to a temperature of 2500 F in an oxygen free environment??? How it would hold up as a piston rings is unknown. Turbine is the only way to go. There are a lot of small turbines around if installed in a housing designed for thby Rolly - SteamStuff
Re: steam cylinder oil - 6 weeks ago
An oil burner takes liquid fuel oil and put it through a fine nozzle and brakes it up into small droplets. The higher the pressure the more droplets and smaller in size and the cleaner burn. I would start at 200 psi if your pump will go that high some pumps are rated 175 psi and most go to 300 psi. if your pump is rated 300 psi I would go to 250 psi with a smaller nozzle that would give you thby Rolly - SteamStuff
Re: steam cylinder oil - 6 weeks ago
Jim I through of something, most pumps will go to 300 psi. smaller nozzle higher pressure. Also check with the oil burner guy you talked to about the best spray pattern for your combustion chamber. Short and wide, long and narrow or whatever. Rollyby Rolly - SteamStuff
Re: steam cylinder oil - 6 weeks ago
Jim the other thing that can affect the smoke is how tight the gas pass space it up through the boiler/generator. When I built ma Derr boiler I calculated the gas pass space as laminator flow but built it as turbulent flow, same gas pass space but harder and longer passage space. I calculated it for six gal per hour Smoked terrible and caused combustion chamber explosions. I built a two stage buby Rolly - SteamStuff
Re: steam cylinder oil - 7 weeks ago
Jim there is a formula for combustion size for burning atomized oil. I can’t remember it and am not quite sure where I have it at home. Go to a good oil burner supply house and they can help you. It may just be the type of nozzle and spray pattern your using. Rollyby Rolly - SteamStuff

Re: Ashton Valve Company - 3 months ago
A lot changed after mid 1918 when FE Stanley rolled over the 1918 car with the piston valve engine in it and got killed. I believe it was after this the business got sold and moved out of the Boston area. The piston valve engine was never used or further developed. Up until this time both the Stanley factory and Aston valve were only a few miles apart. Rollyby Rolly - SteamStuff

Re: Ashton Valve Company - 3 months ago
Rick as far as I know all Stanley’s used Ashton gauges. Both of my Stanley’s did as you can see by the attached photos. Repairing them is another matter as I have stated before. You can retain the gauge case and replace the inners (bourdon tube assembly) from another gauge of the same pressure and one that fits and retain the face, but I have never found a company that repairs a leaking bourdoby Rolly - SteamStuff

Sometimes SACA-NE have their meeting in October there and I get a report in the newsletter. Do you know who is running the place? Was the Corliss running? Rollyby Rolly - SteamStuff
Re: Looking for gauge repair service - 4 months ago
Thanks Pat I also have on the dash or I should say through the dash the bent brass wire from the bucket water level gauge that would have been on the EX, Look above the main fuel valve. It’s weighted on the other side to keep it upright. When I have goon to a Stanley meet I have been asked where is my reflex gauge? And I show them the bent wire and wiggle it and say the water full. They never seby Rolly - SteamStuff
Re: Looking for gauge repair service - 4 months ago
Rick When I built my water level gauge with liquid level probes I wanted it to look like a regular Stanley gauge as possible. I photographed a Stanley gauge to capture the details of the letters. I had found a women that did hand engraving, I made up the brass plate and a cad drawing for what I wanted. She engraved the lettering. I then sent it out to have is silver plated.

Re: Looking for gauge repair service - 4 months ago
Rick About twenty years ago my Stanley gauge after about an hour under 500 LB boiler pressure would start to fill with water, the Borden tube had a hole in it when it got hot. I could not find it and it only leaked when the gage got hot and under pressure. I sent it two several gauge repair shops and no one would repair or replace the Borden tube.

Re: Force circulation steam generator design - 5 months ago
Rick Many boilers have a mono tube section most often used as a feed water heater to recover heat loss in other areas as in high stack temperature. See my marine boiler photo. - Water Tube Boiler, some examples are a Derry (Scott's Stanley), Felt and Black Staff (Boat Boiler) along with my future Stanley replica Ofeldt. Important to note that these have natural circulation. ( and induced ciby Rolly - SteamStuff

Re: Force circulation steam generator design - 5 months ago
Rick I will not be going to the Fall Meet. Are you going to talk about Force circulation steam generator design or mono tube generators. Forced circulation has a complete circulating path. Unlike the Doble and White mono tube generator. As far as I am concerned both Doble and White generators were pour designs and most people copy them. The most work done in any boiler or generator is whereby Rolly - SteamStuff
Re: Coburn Benson - 6 months ago
Pat I wish you well on your remission. At our age we miss many old friends each year. I did a complete set of cad drawings for him so as he could machine one of his narrow frame castings and build up the narrow frame engine. Maybe someday I’ll find out what happened to that engine.

Re: Rectangle steam cycle - 6 months ago

Re: Force circulation steam generator design - 7 months ago
Rick You poster under forced circulation steam generators and talked about mono tube generators. A mono tube generator has no circulation. Water comes in one end and steam comes out the other end, the output is dependent on the total water in and the balance of the amount of heat applied. The word circulation means returning to the starting point. There is no returning in a monotube A forcedby Rolly - SteamStuff

Most of all Herreshoff drawings and works, over 13,000 drawing and papers are at the Hart Nautical museum at MIT in Boston Mass. I had opportunity to review a lot of the drawings around 1985.

A year or so ago I had an article on forced circulation boilers in the Bulletin about the one hundred boats Herreshoff built using them 1870, one boat was 120 feet and the generator was 12 feet tall. I built a model of this generator. The pump was not shown as they were attached to the engine.
