In March 2009 the MAERZ PFR (Parallel Flow Regenerative) Shaft kiln was commissioned at our Peggau plant. The new kiln producing highly reactive quicklime has an authorized capacity of 300 tons per day. Apart from natural gas it can be operated with pulverized solid fuels like brown coal dust. The energy efficiency of the PFR kiln is very high so that it saves 18m³ of gas per ton lime versus the previous kiln. Of course this influences the CO2 balance positively. The PFR Kiln in Peggau is the first lime kiln in Austria with a permanent monitoring of emissions like dust, SO2 or NOx.
