Hard feedwater
The hardness of 8°n was conducive to rapid accumulation of sediment on heating surfaces.
Case study / Steam boiler room
Fako: less fuel.Heat exchange recovered.
Deposits and frequent cleaning revealed a water quality problem. We descaled the boiler, adjusted the parameters and launched KCAQUA 303 to maintain the result during daily operation.

Diagnosis of boiler room
The sediment was a symptom.The source was water.
One-time cleaning didn't solve the cause. At the same time, water quality, blowdown and dosing had to be arranged.
Supply Water
Too high conductivity
The conductivity of 4200 μS increased the risk of sediments and hindered blowdown control.
Frequent cleaning
Short cycles between cleanings burdened maintenance and hindered work planning.
Workflow
From sludge removalfor stable work.
We first restored the heat-transfer surface. We then set up a programme that limits the conditions promoting renewed scale formation.
Water analysis and inspection
We checked the hardness, conductivity, pH and condition of the heating surfaces.
Chemical descaling
The right process dissolved the sediment without dismantling the system and restored the heat exchange surface.
Startup KCAQUA 303
We've determined the dosage, the parameters and the response to the deviations.
Monitoring after implementation
We compare water parameters, media consumption and clean-up intervals.
Data result
Less fuel.Longer boiler work.
The change was assessed not by the appearance of the installation, but by parameters, fuel consumption and intervals between subsequent cleaning.
0
Fuel
Reduced consumption after heat exchange recovery
The comparison was referred to the boiler work before implementation.
4200→2800 μS
Conductivity
Safer water running range
The parameter stopped obstructing blowdown control.
3→12 meat.
Maintenance
Longer cycle between cleaning
Less intervention and easier planning of boiler room work.
The values are exemplary. The actual effect depends on fuel, load, boiler condition and water quality.
Maintaining effect
Program maintains effectafter cleaning.
We're not just preparing a recipe for the boiler room. We determine what to measure, when to react and how to show the result to the technician and board.
Parameters instead of conjectures
The hardness, conductivity, pH and operational data shall be measured in a fixed reference system.
Boiler dose
dosing and blowdown are not based on a one-off setting, but on current observation.
Report ready for decision
We compare the trend of parameters with fuel, water and maintenance requirements.
Implementation FAQ
Questions Beforesimilar implementation.
Below we respond specifically, without promises that cannot be confirmed in the data.
Does boiler descaling require a long shutdown?
The range depends on the state of installation and cleaning technology. First we evaluate sediment, material and working conditions, and then we set a safe time and course of work.
Can scale return after cleaning?
Yes, if the water quality and the way of the boiler is not changed. Therefore, cleaning is combined with the KCAQUA program, parameters control and dosing monitoring.
How do you verify the impact on fuel consumption?
We compare data from before and after implementation, taking into account boiler load, steam production, fuel quality and changes in process. The drop alone is not sufficient for a fair conclusion.
