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?

Injector - Wikipedia

The injector may be defined as a boiler feeding pump, utilizing the velocity and condensation of a jet of steam from the boiler to lift and force into the same boiler a jet of water many times the weight of the original jet of steam. The injector offers definite advantages over mechanically operated pumps when cold water make-

Polly Model Engineering: Technical Notes

Oct 11, 2003 · Turn a steam valve on in the cab and the pump started to inject the water. The other way was the "classic" water injector. First the fireman or the engineer would turn on a water valve to get water to the steam valve just before the boiler, then the steam valve was turned on and the steam pressure equalized the piping from the valve to the boiler.

the boiler. This injection of water is many times the weight of the original jet of steam. The injector is used to some extent in boiler plants as an emergency or standby feed unit. It does not feed very hot water. Under the best conditions, it can lift a stream of water (that has a temperature of 120F) about 14 feet. The installation of an injector is not a difficult operation because the unit is mounted on the side of the boiler.
