Use this tip sheet and its companion, Considerations When Selecting a Condensing Economizer, to learn about these efficiency improvements. A conventional feedwater economizer reduces steam boiler fuel requirements by transferring heat from the flue gas to the boiler ...
Get PriceThe economizer tubes on a 2400 [psi] subcritical coal fired power station boiler were subject to an annual inspection which revealed that the tubes had sagged. This suggested that they had been exposed to excessive operating temperatures. The power station produced 350 MW of electricity and operated on a tight production schedule.
Get PriceContinuous steam output leaves insoluble salts in the boiler water which deposit at the bottom of the boiler. To prevent boiler damage, these deposits must regularly be removed from the boiler. This can be done by abruptly opening a blowdown valve for about two seconds at 240 - 480 minute intervals, depending on the steam space rating and water ...
