Steam boiler

Generates Steam From Water  Steam boilers or distillation plants generates steam from water. This steam is required in many applications in industry, mostly for heating purposes. Very high temperatures (150°C) are used in these machines which are frequently very large. Since a great deal of energy needs to be used to generate this steam, operators cannot afford scale deposits impeding heat transfer so that virtually all installations of this type are operated with specially conditioned water. This very low-mineral water is extremely aggressive so corrosion occurs in all of these steam generators after a short operating time. To reduce this corrosion in the steam boiler, so called corrosion inhibitors are added in the feed water of the boiler.
In a lot of cases, even adding such anti corrosion chemicals, still corrosion can be found in the boiler and the blow down water is often dark brown.

Pursanova TM can be used in such applications for two purposes.
Firstly, Pursanova TM reduces corrosion or stops it entirely. This can generally be determined very easily by measuring the rust or iron share in the blow down. Even after only a few weeks, it can be seen that these values drop appreciably.

Secondly, Pursanova TM is also capable of reducing scale deposits in a steam generator. The water used in steam boilers often are softened and have no calcium left, so no or only very little scale will be found in the boiler.

But there are cases, where untreated city water is used as feed water. In such cases scale can be found in the boiler.
ATTENTION: If Pursanova TM is used to reduce scaling in a boiler, there might be needed to change the blow down frequency and the amount of blow down. So please contact Pursanova TM personal for getting guide lines in this case.
