It certainly makes sense to get some use out of the wasted heat. But most steam locos I see in photos don't have the apparatus on the nose. Were there other places that these heaters were installed on a loco?
"Only about 12% to 16% of the exhaust from the cylinders is required, leaving a remainder amply sufficient to take care of the draft requirements without nozzle adjustment."
What exactly does that mean?
Further economy is obtained by reclaiming the condensate.
I assume that in the original engines, the steam was exhausted out of the cylinders into the atmosphere. The condensate reclamation took the exhausted steam and condensed it back to liquid and put it back in the boiler?
A closed system for the water to steam to water would have certainly been possible... with hardly any loss of water, negating the need to stop for water at all. But I suppose the energy requirements to move that water around made it less efficient than to just exhaust it into the atmosphere?
