Hi, Rick, Is it possible to post that steam generator calculator here? Sergeby russt - SteamStuff
Pulse burning encreases heat transfer rate, such boiler could be more compact and tubing could probably to some extent to silence that terrible noise of the pulse jet... but who knows to what level... Sergeby russt - SteamStuff
Chuk, thank You very much. Ken, seems You are right, but Mr. Drake says that this superheat is a "secret" of his bike. Seems like he wants to overcome cooling effect of one inlet/exhaust port. Wow, 478C for slide valve engine! Thank you guys Sergeby russt - SteamStuff
Hi, guys. Can anybody tell the number of superheat temperature that man has in the boiler of his beautiful bike? I listened many times and failed to recognize. Sergeby russt - SteamStuff
Hi, Don You already have tubing surface area more than adequate for 500 pounds an hour steam rate at least, with at least 80% efficiensy and You want go for even more tubing... Would it not be better to optimise stack arrangement You already have? Less tubing is a more compact and lightweight boiler... Look at already known arrangements of good boilers and You will see more dense wounding of coiby russt - SteamStuff
Well, so may be the blowby goes another way. May be there is too big spacing between the tubes in the last section of tube stack within the row in the coil and so lower heat transfer coefficient. (Exessive passage area for gases and so lower velocity because cooler gases have bigger dencity) By the way, Abner Doble marked in his notebooks that without packing along outer shell of tube stack, perfoby russt - SteamStuff
Hi, Don On Your pictures it is seen rather wide central hole in the coil stack. Seems like You did not buffle it and this passage works and lifts exgaust gases temperature. Need to be clogged all through the length of the coils layout like on Rolly's picture. Sergeby russt - SteamStuff
Hi Ken As I understood all that matter by diagonal scanning... Here heat used not for direct making steam but for splitting water (not without some energy lost of course). After that this heat recovers to the cycle in the form of highly superheated steam produced by combustion of hydrogen in the oxygen with cooling by saturated or even “normally” superheated steam. Such steam otherwise wouldby russt - SteamStuff
Sure, Jamison, they did. They did even more mistake not to hire me as steam consultant for their project (ha-ha-ha) I would never permit those cuttings...and of course made them to pack that cylinders full of smaller tubing or throu all that away and weld something a la Derr boiler and make steam forced draft in the stake, stronger intake valve spring like in youir lawn tractor convertion or evenby russt - SteamStuff
Hi Rick, Those Russians hardly ever heard about Steam Club to stole this idea of converting, they know almost nothing about steam either. This idea of converting ICE is common enough all around the world, anyhow. I've read about it in one Rusian steam site about 15 years ago... But all this is just TV show, to attract attention, no more. Not the real attempt to build real steam automobile. Just lby russt - SteamStuff
There is more wonder that they had seventeen(!) parallel streams in evaporative zone and seem had no problems with burnouts.by russt - SteamStuff

"Might lead to some other ideas..." Is it possible to use Bourdon tube of some appropriate old manometer, and some levers instead of needle? Or the acting force would be too small and not enough to move that ball? Sergeby russt - SteamStuff
Hi Don To my regret I can't put link to the thread which could cover the subject. May be special thread devoted to specifically Doble boiler control system even does not exist, but there are really lot of materials about controling monotube, spreaded among different threads. When I read them around other steam stuff I came to understanding how it works. And I've spent couple of years on it, thoby russt - SteamStuff
Hi, Don Your question many times covered in this forum very informative. Just read thoroughly appropriate threads and follow appropriate links. There lots of info. Best luck. Sergeby russt - SteamStuff
Hi Jamison Hope You did not forget about "chicken & egg" question. Make initial head to the system. Feed water flow will help. Good luck, Sergeby russt - SteamStuff

"Just thinking, if we want electronic feed water control, how about attacking it right at the pump inlet valve? We could replace the inlet check valve with a check valve having a solenoid function that holds it open....in other words, turn it into an electrically activated unloader valve.

Hi Ron In my proposal spring does not regulate anything. It only serves to help to return counter piston to it's bottom point on the suction movement of the working plunger. The movable stop regulates volume of the delivering portion of water. When working plunger begins to press water in the chamber it can not create pressure because counterpiston moves back until rests onto it's (adjustible)by russt - SteamStuff
Two coins more to this discussion. There is one more way to control feed flow from the pump. It is counter piston which has movable stop above it letting this counterpiston move trom zero movement to full stroke of working piston. This counterpiston may be loaded by light spring to not cause any vacuum on the suction stroke of the pump. When You need full delivery of water You rest this stop so thby russt - SteamStuff
Hi Jamison! Solid fuel fired steam vehicle is the way to go! A real steam workhorse must eat solids and drink from the road puddles... I’m working on this way too. And this is no easy way. After some search there came that the best way to deal with solid fuel to my opinion is what John Wetz brilliantly pointed up in his woodgas fired systems. Solid fired boiler with a coils of a little therby russt - SteamStuff
Jamison You got it right. May be You will start slowly and everything will be fine, but... Who knows, may be You will want to outrun Rick and will start too sharply... I would not like You got new sertificate this way. Sergeby russt - SteamStuff
Jamison! Beg You, weld two curved tubes onto the frame beyond the rear wheel, or shift the wheel back 15". Your mustang wants to capsize!by russt - SteamStuff
Jamison, Rick First we should determine for what we need that additional manual pump? If just for starting the boiler and filling it with water for it, then thermo siphoning which Rick proposed is the best way to do. You open vent to atmosphere and turn on the burner for a few seconds then close vent and burner simultaneously and wacuum sucks water in. If it is at least already some water in thby russt - SteamStuff
Hi, Ron You are correct about manual pumping under the way, for a such case of emergency little and quick mechanical pump won't suffice, but Jamison talked about starting procedure, primarily filling the boiler. And for this service manual operating of the main pump can maybe successful. Though that depends on the volume You need to pump to begin firing. If it is one half of a gallon, making onby russt - SteamStuff
Jamison, The spring pump I talked about and which was really made has lever for unloading plunger off the side thrust from the eccentric and along with this this lever can serve for manual operating the pump. Just information for consideration. May be it helps. Sergeby russt - SteamStuff
Ron It is a question I"ve thought alot before and think this situation You described can arise only in the case of refusal of steam automatic or artificial shut the fuel off and if it is so You should close throttle valve too. If all working properly, in the case of low pressure steam automatic should open full fire and max delivery of the pump tuned the way it can not flood the coil as alby russt - SteamStuff
Jamison, Your explanation is absolutely correct. I think Ron appreciated it. Sergeby russt - SteamStuff
Hi, Ron Thank You for the question. Control system is supposingly works the following way.-- (We're all know that monotube is tricky thing.) When You put into the working monotube coil little more water than needs current moment, pressure goes up, though the steam get lower temperature. In the case of the spring pump it is impossible because raise of pressure does not permit more water flow inby russt - SteamStuff
