Electricity consumption can however be optimised further, thus further protecting the climate when using electricity produced with fossil fuels. A new generation of high-pressure fans saves up to 20 % of electrical energy consumption compared to the rotary piston blowers used so far.
Maerz has used this technology in a plant of the Mexican Calidra Group and the operating results have fully met expectations. Calidra and Maerz have also published an article on this in Zement Kalk Gips, which you can find here.
The advantage of the high-pressure fans is that existing kilns can also be converted to the new technology. Depending on the cost of electricity, this investment can pay for itself quickly, so that - in addition to the environmental benefits - you can also derive immediate economic advantages from such a conversion.
