The Scale Problem

Scale layers in pipes and heating elements

The scale problem

The Scale Problem

Water hardness: The higher the concentration of calcium-

carbonate in the water, the higher the “water hardness”

(Measured in ppm, °dH, °fH)

Scale causing typical problems

• Loss of energy due to longer heating times

• Destroyed heating elements and heat exchangers

• High costs of repairs and maintenance of machines

and equipment

• Loss of water pressure due to reduced pipe

diameters

• High cleaning costs and the need of aggressive

cleaning agents

• Decrease in overall industrial productivity

• Sometimes complete failure of the water system

Diminishing energy transfer due to scale deposits

The Scale Problem

Example of an oil-powered boiler system

Energy loss in relation to layer of scale

(in mm) in an oil-powered boiler system

Example: A 500 kW-boiler system at 3mm

scale looses 50 kW (20%) at the transfer

Scale blocks out the heat energy

transfer:

Copper 372 W vs. Scale: 2,2 W

Heat-transfer-drop of factor 170:

causing a large increase in

heating times in a boiler
