A steam injector is a typical application of the principle used to deliver cold water to a boiler against its own pressure, using its own live or exhaust steam, replacing any mechanical pump.
What is an injector on a steam locomotive?
The injector is a simple, if unlikely sounding device that was invented by the the Frenchman M. Giffard in the 1850s. It uses a jet of steam, from the boiler to force fresh water back into the boiler, heating it up in the process. It has been widely used on steam locomotives since its invention.12 Aug 1998
How do steam pumps work?
The steam enters at one side of the steam cylinder through the slide valve and pushes the piston towards the opposite side. As the piston reaches the end of the stroke, the slide valve reverses the steam flow, which reverses the piston movement.
What is injector in boiler accessories?
What Are Injectors? They are a device which is used by crew to take water from the tender and combine it with live boiler steam and inject it into the boiler via a check valve. It is achieved by opening the steam and water valves in their correct order, they will pick up and inject the water into the boiler.
How does a injector work?
Fuel injectors spray fuel into a car's engine using electronic controlled valves, capable of opening and closing many times a second. They have an atomising nozzle that distributes the petrol or diesel evenly, for optimum combustion and efficiency. A car generally has one fuel injector per cylinder.3 Dec 2019
How does a water injector work?
In a piston engine, the initial injection of water cools the fuel-air mixture significantly, which increases its density and hence the amount of mixture that enters the cylinder. The water (if in small liquid droplets) may absorb heat (and lower the pressure) as the charge is compressed, thus reducing compression work.

What are the uses of injector?
injector, a device for injecting liquid fuel into an internal-combustion engine. The term is also used to describe an apparatus for injecting feed water into a boiler. In diesel engines fuel must be in a highly atomized form for proper combustion.
