Decreasing the turbine exhaust pressure significantly increases the specific volume of exhausted steam, which requires huge blades in last rows of low-pressure stage of the steam turbine. In a typical wet steam turbines, the exhausted steam condenses in the condenser and it is at a pressure well below atmospheric (absolute pressure of 0.008 MPa, which corresponds to 41.5°C).

Metropolitan Engineering Consulting and Forensics - CAUSES OF DAMAGE TO BOILER

As the unit cools, the steam condenses and water level drops, which allows the pressure to drop. If the steam drum vent is not open when the unit is cooling, a vacuum condition can result. A vacuum on a boiler can cause problems with leaks on rolled tube seats of generating tubes, which are designed for a mechanical fit to withstand positive pressures.

Steam and Condensate - A basic overview of a steam system - The Boiler House

When steam condenses, its volume is dramatically reduced, which results in a localised reduction in pressure. This pressure drop through the system creates the flow of steam through the pipes. The steam generated in the boiler must be conveyed through the pipework …

6 Reasons Why your Bolier is Leaking - Surewise.com

18/12/2020 · Here are six possible likely reasons that your boiler may be leaking. 1. There is a leak from the bi-thermal heat exchanger between the heating and hot water bodies. 2. The expansion tank has failed. Watch the boiler as the water heats. If the leak starts after the boiler burner has run for a while, then you most likely have a faulty expansion
