Steam Condensate Pumps | McMaster-Carr

Move a higher volume of condensate than standard steam condensate pumps. Use these pumps in low-pressure steam systems to capture hot condensate and return it to your boiler or feed unit. They turn on when the tank is 2/3 full and turn off when condensate drops to 6" deep.

Expert systems and coal quality in power generation

can be a major contributor. Coal quality (that is the properties of coal) has an impact on many parts of a power plant including the coal handling facilities, pulverising mills, boiler, air heater, ESP, ash disposal as well as stack emissions. Figure 1 is a diagram of a typical pulverised coal combustion power station.

Jan 23, 2018 · In general, the power plant boiler feed pump is sized to provide full feed water flow, plus some amount of spray water, all at maximum continuous rating (MCR). In theory, this point should be as close as possible to 90 percent BEP (leaving a little extra to recover from low drum levels at full load, and during transients). 3.
