[Steam-engine] boiler feedwater injector conection

[Eric Applegate]

There is sure nothing wrong with having two injectors.  But (and there is always a but) it is hard to beat a good duplext pump on a stationary setup.  The idea being that you can set your pump to run as fast or as slow as you want, and basicly what you want is to replace the water at the same rate you are evaporating it.  So if you are using up steam then the pump is replacing the water while you are working.  With and injector you will run your engine.  Use up the steam the replace the water with the injector.  The boiler will cool off lose presure and slow down the engine.  Now how much the new water efects your boiler is determined by how good an operator you are which mean lots of thing and knowlege is the key.  

That was just rambling on here is advice.  Two ways of puting water in a boiler is a must.  Three is even better and I don't think you will have any one call you redundent if you had four.  What if one injector over heats and wont draw water anymore?  It happens.  It is plumbed up right next to a now very hot second injector.  If that were my ONLY two ways of getting water in the boiler I would be sweating it a little.  OK so it turns out this is rambling too.

Safe bubbles
