The reduction in volume of changing steam to water is a reduction in volume of 1700. The rapid drop in pressure from a positive steam pressure to a vacuum causes some of the water in the boiler to instantly change to steam as the pressure drops and this steam quickly causes water in the boiler to evaporate lowering the water level.
2020-2-10 · If condensate isn't returned to the boiler, the steam system must make up the loss with cold, untreated, raw water that has to be prepared for boiler operation. This preparation has a cost. The make-up water also contains substantially less BTU content that must be raised in the deaerator or atmospheric feed water heater.
2019-11-21 · The Heat Shield™ High Heat was used during a 60-day trial for steam pipe insulation at a hospital. The application used an 8-coat coverage, which is approximately 8/1000'ths of an inch thickness and provided a 110F (61C) temperature reduction, lowering the surface temperature from 302F (150C) to 192F (88.9C) degrees.
