cooling temp of clinkar production

Chapter 23 Cooling Water Systems-Heat Transfer SUEZ

Efficient removal of heat is an economic requirement in the design and operation of a cooling system. The driving force for the transfer of heat is the difference in temperature between the two media. In most cooling systems, this is in the range of 10-200 degrees F. The heat flux is generally low and in the range of 5,000 to 15,000 Btu/ft 2 /hr.

temperature causes the raw material to react and form a hard nodular material called "clinker". Clinker is cooled and ground with approximately 5 percent gypsum and other minor additives to produce Portland cement. The heart of clinker production is the rotary kiln where the pyroprocessing stage occurs.

Cement Kilns Clinker Thermochemistry

The rawmix enters a kiln system at a temperature close to ambient, and the temperature rises as it passes through the kiln system until it reaches a peak temperature in the sintering zone, after which the chemical state of the clinker is frozen by rapid cooling. During the process of temperature rise, chemical reactions take place in sequence.
