Pentol Flue Gas Conditioning adds a small amount of SO3 to the flue gas. Just enough to reduce the fly ash resistivity, the ESP can now collect the dust properly and is running at its design capacity. Changing coal is getting easier, as the operator can simply increase or decrease the injection of SO3, preventing the need to mix different coals.
Typical flue gases from natural gas-fired power plants may contain 8-10% CO 2, 18-20% H 2 O, 2-3% O 2, and 67-72% N 2; typical flue gases from coal-fired boilers may contain 12-14 vol% CO 2, 8-10 vol% H 2 O, 3-5 vol % O 2 and 72-77% N 2.

25/01/2021 · After wet desulfurization, coal-fired flue gas contains enormous amounts of water and waste heat that can be recovered for energy savings. Compared with the conventional condensation method, the application of an open absorption heat pump
The emissions Of SO3 from such a boiler depend on coal sulfur content combustion conditions flue gas characteristics and air pollution devices being used. It is well known that the catalyst used in the selective catalytic reduction (SCR) technology for nitrogen oxides (NOX) control oxidizes a small fraction of sulfur dioxide (SO2) in the flue gas to SO3.
