With the PFR kiln, Maerz has developed the lime kiln with the highest thermal efficiency. But power consumption can also be optimised.
Every combustion process needs oxygen and every lime kiln needs cooling air. In lime kilns that work with overpressure (such as the Maerz PFR and HPS kilns), the air was usually compressed using entire batteries of rotary piston blowers.
Today, high pressure-fans can deliver the required volumes and pressures for combustion and cooling air with a single machine each - and with up to 25 % less power consumption than rotary piston blowers. We already have these fans successfully in operation - please read our publication and customer success story.
