The amount of unburned carbon in the fly-ash of coal power stations is a measure of the efficiency of energy extraction. When the maximum efficiency is reached by optimizing the combustion process, the pollution emission is also reduced to a minimum. Experience has shown that this optimum condition is reached when the carbon content in the fly-ash is 2-4%by weight.

Berthold Technologies offers a measuring system that accurately, quickly and reliably, determines the carbon content of the fly-ash. This allows the power station operator to optimize the combustion process.
