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.

Prediction of Creep Failure Time for Pressure Vessels

When a pressure vessel is subjected to internal pressure and is made from a material which exhibits creep, the vessel will expand. If the internal pressure is held constant during expansion, the load on the wall will increase.

How Power Plant Boiler Works? -

The boiler generates high pressure steam by transfering the heat of Combustion in various heat transfer sections. This article briefly describes the flow and arrangement of the heat transfer sections in a boiler. In line diagrams help make the concept clear.

Adjusting the Boiler Code Mechanical Engineering
