Water Injectors For Steam Boilers

Boiler Chemical Injection

Steam boiler chemicals are much different then hot water boiler chemicals. To keep it simple we will just concentrated on boilers less then 200 psi, since this 95% of the boilers out there. There are four main components used to treat steam boiler chemicals oxygen scavengers, alkalinity builders, condensate treatment, and polymer or phosphate

Scale Traction Engine – installing a steam powered boiler

Feb 17, 2018 · The full size original R3 (see previous post for photos) has a steam powered injector, which uses boiler steam to suck up water from the tender tank using a venturi effect, then using black magic passing the steam+ water through some cones, increases the pressure which forces the mixture back into the boiler.

Pumps and injectors for a monotube or flash steam boiler

Ive been thinking about flash boilers recently, and was wondering about pumps- does anyone reckon either a steam injector of the type used with model locos or a stuart turner steam water pump could be used as the main pump, after youve got the boiler producing steam and running with a hand pump?

The importance of high-quality boiler feedwater and why

cool incoming water. Water passing through the injector must be all liquid so that the incoming water will have enough weight to drive against the boiler water pressure. Thats why the steam must also condense. As you know, hot water or a hot injector refuses to work. It can't condense enough steam to give the water enough weight to buck the boiler water, even though it still has velocity.

how steam injectors work - YouTube

The injector was originally used in the boilers of steam locomotives for injecting or pumping the boiler feedwater into the boiler. The injector consisted of a body containing a series of three or more nozzles, "cones" or "tubes". The motive steam passed through a nozzle that reduced its pressure below atmospheric and increased the steam velocity. Fresh water was entrained by the steam jet, and both steam and water …

1. An injector is a steam jet device by means of which water from the tender of the locomotive can be forced into the boiler against the boiler pressure. Injec­ tors may be of the lifting type or of the non-lifting type, or may operate on a combination of both the lifting and non-lifting designs. All lifting injectors, and some non­ lifting injectors, operate with high-pressure steam from the boiler.
