Heat Exchanger


In cement industry, heat exchange often installs in the clinker cooler dedusting system, to cool down the gas temperature to a requested level. The hot gases from clinker cooler in normal condition is 200~250℃, in upset condition can reach higher than 450℃, therefore the hot gas must be cool down before it pass through bag filter for dedusting process.


Principles of operation
In the operating of this unit, hot gases from the clinker cooler process are pass through numbers of vertical parallel tubes and cooling is accomplished by forced convection induced by cross flow fans moving ambient air over the outside of the tubes. Heat Exchange works very well with bag filter, especially in clinker cooler process.
 

Gas conditioning tower is a pre-handling equipment for increase gas moisture in the kiln process of cement production line. Through a water injection system, the gas can have higher moisture, lower temperature and lower resistivity, and at the same time benefit the Electrostatic Precipitator efficiency.
