The operation of the oxyfuel clinker cooler prototype indicates that boundary zones, such as the cold clinker discharge system, demand special attention regarding minimisation of false air ingress also in industrial scale projects. Moisture content of the recirculated cooling gas was much higher than expected. This was attributed to the

Typically, the clinker coolers release large amounts of heated air at 250 to 340° C which can effectively be used in WHRS system. The steam turbine based waste heat recovery boilers (WHRB) are placed between the cooler and the de-dusting system. Depending on situations / requirements, various configurations are considered which are shown below.

Clinker Coolers August 20, 2022 In cement manufacturing, formation of clinker nodules occurs at the entrance to the hottest part of the kiln with a material temperature of around 1280°C. The clinker is preferably in the form of 10-mm to 25-mm size nodules that exit from the front end of the kiln into the cooler.
