The injection takes place at the rear part of the clinker cooler, immediately upstream of the gas outlet. Depending on the space above the clinker cooler, the nozzles can be attached both on the top and the side. We usually offer spillback nozzles for controllability.
In comparison to conventional single-fluid nozzles, spillback nozzles ensure consistently fine droplets over the entire control range.
In addition to direct injection into the clinker cooler, injection is also possible into the duct downstream of the clinker cooler. This requires a sufficiently long and straight running evaporation section.
