Cement making is a power consuming business. Pyro string and downcomer are perfect spots to lower emissions and save energy with PROMECON’s flow meters. Even efficient vertical roller mills (VRM) offer an optimization potential by better and more reliable raw gas flow measurement. Hot and most dusty gases from rotary kiln, pre-heater tower and clinker cooler can be measured faster, accurately and without any maintenance which opens a huge potential for combustion optimization like the kiln ID fan control.
