Explanation:

  • An injector is a boiler accessory used to inject water into the boiler.

  • The function of the injector is to supply the requisite quantity of water to the boiler against the steam pressure.

  • Injectors are used in steam locomotives and ships to feed water into the boiler to produce steam.

  • The injector works on the principle of the Venturi effect, where a high velocity fluid creates a low-pressure area, drawing in and mixing the second fluid.

  • The injector consists of a steam nozzle, a valve assembly, and a water supply pipe.

  • The steam nozzle creates a high velocity steam jet, which creates a low-pressure area in the mixing chamber.

  • The water supply pipe delivers water to the injector, which is then mixed with the steam in the mixing chamber and enters the boiler.
