<HTML>Looking at the lamont boiler was wondering if a steam injector .
Would adversely affect the recirculation operation if one was used to replace the pump shown in the lamont article.Assuming the same capacity
(volume rate) as the pump.</HTML>

<HTML>Arnold,
I believe there were attempts to use injectors instead of the physical pump but they do not seem to have been adequate. For example, when the boiler is cold and started up there is intense heat input to the Lamont circuit but no circulation/no steam available. The basic premise of the Lamont is to ALWAYS have 4-5X the full boiler output going thru the Lamont circuit to absolutely protect it under all conditions.
There is the possibility that a circulating pump could be used for starting and low output conditions with a "takeover" drive attached to an exhaust turbine as used in some of the Dobles. This would mean the higher the boiler output the faster the circulating pump and other auxilary equipment would be driven---just like the Doble-- and the electric pump drive would be taken over by the exhaust turbine. Been away for a few weeks, hard to get the ol' mind back into steam gear!

<HTML>I believe injectors rely on hot steam and COLD water,,,,wont work if feed is too hot,,,,they will not work over a wide press range,,,need a diferent nozzl for each range,,,,anybody got details on limits??? Cheers Ben</HTML>

<HTML>Ben,
I agree, but always try to hug the side of great caution---as you know it takes a lot of money to build a prototype boiler and it would be terrible to ruin it in testing alternative circulating systems. Rod's boiler is only drawing 6 amperes @ !3 volts and that is good enough for me. Will leave it up the the younger and more aggressive experimenters to come up with a simpler/better system. HEY! did you look at the Ormond Beach photos? If anyone knew what the straight eight was and the white car #15 it would be you Coburn.
Bill Barnes is going to be at our POWOW meet in June with his Vanderbilt(that beat the 1921 Mercedes) , do you think you could make it with your demonic black Vanderbilt??
Thanks for everything Ben, George</HTML>

<HTML>Cobern,
There are a few injectors that have dependable operation over a fairly wide range of pressures but they must be feed cold water or the vacuum will make vapor out of it and stop the flow. Injectors seem best suited to lifting water to fill tanks or on low pressure systems like that of a locomotive.

<HTML>Hi,,,While were on this subject,,Has anyone added a injector to a Stanley as a backup,,,,VanDine had a small Marsh pump on his 13 roadster for added pumping for the climb up MtWashington,,,He had worked at Stanley F back around '20-- and was part of the crew that sold to Tommy Durr,[1934?],,,hoping that Tom could figgur how to pay them,,,,timeswere TOUGH ,,,,There is a fellow west of Boston who has spent a lot of time fiddli'n w/ jecters,,,,cant recall his name,,,,,,Had a certified [Mass] biler in his Buffalo roller at Waltham steam meet a few years back,,That was the day they also had a steam PUMPER throwin a healthy stream into the Charles[river],,,,,Oh yeh theres a JUMBO AMOSKEAG at auction May 3 at the Amderson museum if theres any fire buffs around here,,,,Cheers,,Ben ,,,,p/s mornin temp 22f,,,,,send a cheerup to George,,who may have a relapse if he gets up too early this mornin,,cb</HTML>
