When you use steam from a boiler, you need to add more water to avoid the risk of an explosion. If the steam pressure is at 200 psi, how do you use this same steam pressure to force water into the boiler at a pressure greater than 200 psi.
You can use a pump, BUT you can also use an injector which uses only steam, without any moving parts, to inject water into the boiler. This book is a brand new reprint from the U.K., of an 1893 text book on injectors. You get detailed text, loads of drawings, plans, charts, and probably more maths than you'd like. But there is more in this book on injectors than I can ever remember seeing elsewhere. The chapters don't have titles, but a quick thumb-through will get you interesting details on lifting, automatic, and restarting injectors, flag nozzles, compound injectors, ejector condensers, water injectors, air injectors and more.
Perhaps a little expensive, but a top rate book.
