This is also the temperature of the water at that steam pressure. When an injector is operated, the water passing through the injector on its way to the boiler is heated from 160 to 200 degrees F (71 to 93 degrees C). It is therefore from 183 to 223 degrees F (102-124 deg C) cooler than the water within the boiler.
