Aug 09, 2016· After that condensed water with the feed water passed to the economiser where it gets heated up by the economiser. And finally the feed water enters into the boiler by a feed water pump to repeat the cycle. The burnt flue gases from the furnace passes through the super heater, economiser and air pre-heater.

Optimising power plant efficiency by measuring silica

For example, a typical fossil-fuel power station converts around 650tons of water into steam per hour, in each of four 160MW boilers. This represents around two million tons of water usage per month. With such a large output of water in the steam process, the chemical quality of the water is critical.
