This answers the question I had about the steam engine being a "batch process" or a "continuous process". I thought it was a batch process because I figured there was no way you could overcome the high pressure in the boiler once it gets really hot. Back in the early days there was no such thing as a pump that could deliver water into the boiler with a higher pressure than the boiler pressure. So, you're really "stealing" some of the energy (via the recirculation of steam) from the top of the boiler to "force a suction" of water and deliver it into the boiler at a higher pressure than what's in the boiler.
We use the steam injection in our boilers at work. The steam injector is connected to a feedwater tank that then pumps that water into the two high pressure boilers. It’s a way of saving energy and money.
I had not given this a thought until recently, a model maker told me about clack valves feeding the boiler in a similar way.
What is clack valve??
beautiful explanation and demonstration. Thanks
Well, the check valves can get stuck open (usually remedied by a good thwack with a hammer), and the injectors can stop working if they get too hot.

thank you for this super easy to understand explanation + historical background!
If im not wrong you mentioned at last .. nozzle area increased hence pressure increased ??
Good info. Thanks.
Thnq sir, informative
Wouldn't this be a great way to cool reactors, that way the coolant water gets in, even if the generators don't work.
