Valmet has long experience and plenty of references in recovery boiler scrubbers for removing sulfur oxides (SOx) and dust, as well as for heat recovery from flue gas. "In conventional power boilers, NOx levels can be reduced with selective catalytic (SCR) or non-catalytic reduction technologies (SNCR).

A conventional feedwater economizer reduces steam boiler fuel requirements by transferring heat from the flue gas to the boiler feedwater. For natural gas-fired boilers, the lowest temperature to which flue gas can be cooled is about 250°F to prevent condensation and possible stack or stack liner corrosion.

Mar 03, 2021 · High pressure steam boiler stack temperatures often range from 400 degrees F to 650 degrees F. That high temperature exhaust is wasting energy. That is where boiler economizers come in to reduce that heat loss. Remember, we need a fluid that can use the heat AND is at a lower temperature than the flue gas. Dry Economizer

Heat transfer is reduced. The gas temperature needs to be raised to keep the steam quality constant. With rising gas temperature, more ash is collected on the pipes, increasing the deposit problem. The deposits formed contain different forms of Vanadium oxides. These are corrosive by themselves and act as catalyst to oxidize SO2 to SO3.
