Making Boilers More Efficient - ASME

2012-9-18·In what became a 24-month process from initial concept, design, and validation through testing, engineers at Cleaver-Brooks started by designing a new boiler incorporating the idea of changing the burner, says Wisinski. One critical factor was a re-design of the tubes within the boiler to increase heat transfer in the tubes.

Basic Steam Theory - Steam Pressure - iForm

2008-10-21·The boiler is virtually a closed vessel. So as more steam is generated inside this vessel, the steam must compress to find room for itself. As yet more steam is generated it becomes even more compressed and its pressure continues to increase accordingly. This pressure of the steam is exerted in all directions. Gauge pressure is the

DEARATOR EXPLOSION - Boiler and Pressure Vessel

2008-10-19·It was a combination of sudden high pressure increase and the HIC which resulted in the failure. It would be interesting to find out if the deaerator in this thread was constructed of SA-516 70 and if it was PWHT'd. There are really only two sources of sudden pressure increase for the deaerator: steam headers and boiler feedwater.

How does pressurizing of a pressure vessel work

So, initially, when the discharge valve isn't opened, the pressure inside the vessel is 0 psig right? What happens to the pressure inside the vessel (pressure gague measuring pressure in the vapor space of vessel) once the pump is started, the discharge valve is opened and the liquid starts flowing into the tank? Why does the pressure increase?
