Nov 06, 2007 · RE: MW Pipe thickness definition BigInch (Petroleum) 5 Nov 07 11:14 Thought about that one, but never heard of medium weight steel pipe, its always "Std" wt, XH, or XXH, so I went with min wall.Learn More
Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser. From the condenser it is then pumped to the deaerated feed tank.Learn More
Schematic of a wet recirculating cooling water system for a 520-MW Coal-Fired Boiler. In dry cooling systems the steam exhausted from the turbine is cooled by forcing ambient air across a heat exchanger filled with the condensing steam.Learn More
