Reduce corrosion, fouling and steam leaks in boilers
High-temperature corrodes on heat transfer surfaces
Growing deposits set a long sequence of compensation actions into gear.
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.
Sulfuric acid is very corrosive and forms deposits in the same time, blocking the gas passage.
After a few month, a service shutdown is necessary to repair puncture holes or clean the gas passage.
Minimize maintenance and boiler temperature
PentoMag has a great influence on fusion temperature of ash independent of the fuel components.
With PentoMag® vanadium loses its catalytic power, becoming inert and breaks the chain of corrosion damages and heat transfer losses. Vanadium is removed from the boiler tubes and cannot catalyst SO2 anymore.
In the cold-end, this allows to create a corrosion-free environment, neutralizing all condensing SO3 and increasing the time between shutdowns.
Reduce fouling of air preheater from acidic corrosion.
Reduce costs through the decrease of exit gas temperature.
Tailored blends from the range of specialty chemicals
With 50 years of experience protecting boilers from corrosion, Pentol has learned to chose the right chemistry to provide the best price-performance ratio.

We strongly believe that the service related to our products is key for a successful boiler treatment.
The application of a PentoMag® results in a list of improvements
Cleaning intervals for furnace, superheater, reheaters, economizers and air heaters are reduced. Dosing equipment designed by Pentol is of rugged design and requires minimum maintenance.
INCREASE PLANT AVAILABILITY
Reduced corrosion and deposits mean extended lifetime of high and low-temperature sections, allows longer cleaning intervals and less unexpected downtime.
INCREASE BOILER EFFICIENCY
Improved heat transfer, lower O2 and atomising steam consumption, less soot blowing and particularly the possibility to reduce final gas temperature to a minimum, resulting in a substantial increase in boiler efficiency.
PentoMag’s main property is to reduce high and low-temperature corrosion. Reduced corrosion means an extended lifetime of high and low-temperature sections in the flue gas duct.
Reduced fouling increases heat transfer in superheater and air heater sections and reduces downtime for cleaning.
SO3 emission and the visible white chimney plume are reduced. With a reduction of exit gas temperature, the total efficiency of the plant can be increased, resulting in a reduced CO2 emission of the plant.
PentoMag reduces acid smut emission and SO3 emission. Pentol is able to give you guarantees on maximum SO3 emission .
In combination with PentoMuls, we can
REDUCE SOLID EMISSION
REDUCE NOx EMISSION
REDUCE CO EMISSION
PREVENT CORROSION IN THE BACK END
PREVENT PLUGGING IN THE BACK END
INCREASE EFFICIENCY OF THE PLANT
PentoMag® eliminates SO3 and removes the plume of your chimney.
Reducing emission normally comes at a cost. Pentol’s main focus on developing environmental technology however is to reduce emissions by optimize the combustion. This approach is extremely interesting as the cost of Pentol’s fuel oil treatment is always covered by the economical benefits achieved.
