These boilers are commonly constructed in place, roughly square in shape, and can be multiple stories tall. Main steam stop/check valve: It is used on multiple boiler installations. Direct method of boiler efficiency test is more usable or more common. In the 20th century, design practice moved towards the use of steel, with welded construction, which is stronger and cheaper, and can be fabricated more quickly and with less labour. That makes the longevity of older wrought-iron boilers far supe...

Top feed: In this design for feedwater injection, the water is fed to the top of the boiler. Air is often passed through an air heater; which, as the name suggests, heats the air going into the furnace in order to increase the overall efficiency of the boiler. Desuperheater tubes or bundles: A series of tubes or bundles of tubes in the water drum or the steam drum designed to cool superheated steam, in order to supply auxiliary equipment that does not need, or may be damaged by, dry steam. Stea...

1993 - Second site established at Crowthorne giving 50% more space. The second method is by simply using an induced draught fan (ID fan) which removes flue gases from the furnace and forces the exhaust gas up the stack. Since the heated flue gas is less dense than the ambient air surrounding the boiler, the flue gas rises in the chimney, pulling denser, fresh air into the combustion chamber. The steam jet oriented in the direction of flue gas flow induces flue gases into the stack and allows fo...

In December 2011, it was approved by the US-based National Institute of Building Sciences as part of its National Building Information Model (NBIMS-US) standard. The initiative intends Lithuania to adopt BIM, Industry Foundation Classes (IFC) and National Construction Classification as standard. BIM is often associated with Industry Foundation Classes (IFCs) and aecXML - data structures for representing information - developed by buildingSMART. As some BIM software developers have created propr...
