Rotary kiln emissions

All rotary kilns must be equipped with exhaust or flue gas handling equipment, sometimes referred to as a gas conditioning system. This system collects and treats (or “conditions”) any products of combustion, loss on ignition, gaseous emissions, and small particulates leaving the kiln in order to prevent air pollution and control emissions
