Optimize ESP Performance with Flue Gas Conditioning
Pentol Flue Gas Conditioning has more or less the same effect as building an additional ESP field.
Without the need for space, of course. And without changing the ductwork of your plant. And at a fraction of the cost.
Pentol Flue Gas Conditioning reduces solid emission…
- by increasing the efficiency of your ESP
- by reducing the fly ash resistivity
- by injecting SO3 into the flue gas stream.
On the following pages, we would like to show how this works.

Modify fly ash resistivity to let the ESP run on its design point

Avoid the back corona effect at dust collection
SO3 is amazingly important because it naturally combines with the moisture in the flue gas to create sulfuric acid. Sulfuric acid immediately reacts with the fly ash particles to form a thin conductive film, which eventually lowers the fly ash resistivity.
With the precipitator performing at its design efficiency, sparking and back corona is eliminated, extending the lifetime of the precipitator and allowing the operator to run the precipitator on rated current.

Now the SO3 is available for reaction in the flue gas duct. No SO3 is stored in any place and the correct quantity is produced automatically by the system.
Ash particles with lower resistivity have a higher migration velocity and are collected on the dust collector plates. The dust layer adhering to the collector plate is not working as an insulator anymore, allowing the current of the ESP to work in the electric field instead of heating up the dust layer on the plate.
The obvious effect is a very high efficiency of the ESP and easy removal of the dust from the plates. In fact, after a few days of operation, the ESP will be cleaned by the SO3 and after rapping the bare metal is visible. Cycles between rapping of the plates can be extended for lower emissions and reduced stress of the ESP.
