It was designed to air quench and cool large quantities of hot clinker rapidly, and to recover and return to the kiln a major portion of the heat from the cl

Clinker Cooler Drive - Safeguard operation Failure mode: Modern ETA Cooler Traditional Grate cooler Failure of one pump Bypass is opened, clinker production continues Standby pump must be activated Failure of one lane drive Production continues at almost 100% Capacity

It discusses the important parameters determining the efficiency of a clinker cooler and shows how the solutions and market shares of the individual plant engineers differ. Clinker inlet distribution system and a method for operation (22) 29.11. (43) 02.06. (57) Clinker cooling with a cooling grate having a receiving section

Maintaining constant clinker bed height is a key to stable cooler operation. Undergrate pressure reflects bed resistance and changes with clinker size. To maintain constant Undergrate

Clinker cooler transfers heat from clinker to combustion air to improve the heat exchange process and reduce fuel consumption to some extent. obtain clinker at an appropriate temperature for further grinding, storage and conveying. The cement clinker after sintering is not the final cement product sold in the market.

CLINKER COOLER Reduce clinker temperature from approx. 1400 o C to approx 100 ~ 200 o C The heat of the incoming clinker is recuperated in the secondary air of Kiln An efficiency of incoming clinker heat usually lies within 65 ~ 75% 3 Clinker Cooler Type 1. Grate Cooler Cross flow heat exchange through clinker bed with cold air

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.

Robust, reliable hydraulics. As a healthy circulatory system is vital for the human body to function well, so the clinker cooler relies on the health of its hydraulics: the pumps and the hydraulic oil.

The clinker is spread on the grate plate with a certain thickness, and continues to advance with the movement of the grate plate. The cold air flows from the

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
