Friday, April 29, 2011. The locomotive-type boiler is also a characteristic of the overtype steam wagon , the steam-powered fore-runner of the truck. In this case , however , heavy girder frames make up the load-bearing chassis of the vehicle and the boiler is attached to this. Wednesday, April 27, 2011.

Tuesday, August 30, 2011. Oxygen scavenging chemicals are very often added to the deaerated boiler feedwater to remove any last traces of oxygen that were not removed by the deaerator. The most commonly used oxygen scavenger is Sodium Sulfite (Na2SO3). It is very effective and rapidly reacts with traces of oxygen to form Sodium Sufite (Na2SO4) which is non-scaling. Another widely used oxygen scavenger is hydrazine (N2H4). Wednesday, August 24, 2011. Monday, August 22, 2011. The boiler feedwater is spraye...

Thursday, March 31, 2011. Cornish boilers (Fire-tube boilers). For efficiency , the boiler was commonly encased beneath by a brick-built chamber.Flue gases were routed through this , outside the iron boiler shell , after passing through the fire-tube and so to a chimney that was now placed at the front face of the boiler.

Monday, July 25, 2011. British Thermal Unit (Btu). In north America , the term "BTU" is used to describe the heat value (energy content) of fuels and also to describe the power of heating and cooling systems , such as furnaces , stoves , barbecue grills and air conditioners. When used as a unit of power , BTU per hour (BTU/h) is the correct unit , though this is often abbreviated to just "BTU". Labels: British Thermal Unit (Btu). Tuesday, July 19, 2011.

MACHINE WORLD: Spray-type deaerator
http://machinetec.blogspot.com/2011/08/spray-type-deaerator.html
Monday, August 22, 2011. As shown in figure ,The typical spray-type deaerator is a horizontal vessel which has a preheating section (E) and a deaeration section (F). The two sections are separated by a baffle (C). Low-pressure steam enters the vessel through a sparger in he bottom of the vessel. A schematic diagram of a typical spray-type deaerator. The deaerated boiler feedwater is pumped from the bottom of the vessel to the steam generating boiler system. Subscribe to: Post Comments (Atom).

Tuesday, February 16, 2010. A tunnel boring machine (TBM) also known as a "mole", is a machine used to excavate tunnels. With a circular cross section through a variety of soil and rock strata. They can bore through hard rock, sand. And almost anything in between. Tunnel diameters can range from a metre (done with micro-TBMs) to almost 16 metres to date. Tunnels of less than a metre or so in diameter are typically done using trenchless construction methods or horizontal directional drilling. Between Fran...
