In controlling the flow of air provided by the clinker cooler and fed to the furnace and the combustion chamber placed above the furnace in a cement mfg. plant, process is characterised in that the air flow is divided into two currents which followed different paths through the clinker layer ...
Define Clinker cooler. means an installation into which clinker product leaving the kiln is placed to be cooled by air supplied by a forced air draft or natural draft supply system.
As ISIG does the major heat recovery task, for balance Clinker cooling it is equipped with conventional Reciprocating Grate Cooler. Special features of ISIG/DFR over Conventional Inlet No Internal Ducting/manual Dampers Uniform Distribution Of Air Through-out the with Inlet Stationary inclined Grate (...
A model has been developed to calculate the temperature profiles of the clinker, air and wall along the cooler which the air and the clinker are inaccessible by experimental measurement. The model is based on a representation of gas–solid continuous cross-flow heat exchange by a series of stag...
In the grate cooler, the clinker is transported over a reciprocating grate passing through a flow of air. In the tube or planetary cooler, the clinker is cooled in a countercurrent air stream. The cooling air is used as combustion air for the kiln. In developing countries, shaft kilns are...
lite [11]. Thus, the quenching step at laboratory scale mimics what is observed in a cement plant since clinker nodules are usually quenched using a grate cooler [56]. Clinker pellets thus obtained were stored in dessicator, to avoid unwanted hydration reactions....
distribution in at least a measuring plane (38 - 48) above the ventilation floor (18), and characterized by - regulating / controlling at least one operating parameter from the conveying speed of the clinker and / or flow speed of the cooling air of the cooler (10) as a function of ...
onto an inlet distribution in the form of a bulk material bed, also known as a clinker bed. The clinker is then moved onto a grate cooler where it is cooled by cooling air and transported from the kiln to further processing stages, usually at first to a crusher. During this transport, ...
Subsequently, a final cooling8can be effected in a fluidized bed cooler, rotary tube cooler or the like, for example with air. Calcined clay is obtained, which can replace 10 to 40 wt-% of the clinker in cement. The CO2emissions thereby can be reduced by up to 36%. ...
