cooling tower in cement industry
the article will consist of
1- the function of the cooling tower in cement plant
2- comprehensive check up list for cooling tower in cement plant
3- cooling tower calculation

the function of the counter flow cooling tower is :
to cool the hot water coming from the heat exchangers of the blowers and compressors then return the water again to the compressors and blowers to cool them down.
checkup list for cooling towers :
the items which must be checked
foreign objects, pollutants cause completely block of the tower above water tank.
you must maintain the cooling tower until it maintain the below specs
Cooling water capacity: 200m3/h;
· Inlet water temperature: t1 = 43℃;
· Outlet water temperature: t2 = 33℃;
· Atmosphere dry bulb temperature: θ= 31.5℃;
· Atmosphere wet bulb temperature: τ= 28ºC
· Atmospheric pressure: 100.4Kpa;
· Circulating water capacity limit: ≤20mg/L
so what will happened if you ignored the maintenance of the counter cooling tower ?
Increasing the output temperature of the cooling water causing a repeated shut down for equipments and
raising the bearing housing temperature for a relatively long period.
Clear all foreign objects, pollutants and blockage in the packing, water collector surface and
water collecting tank to prevent any clogging; to ensure the normal operation of the cooling
tower. Modifying the return hot water comes from compressor and blower room to enter the
Items needed to be changed
Water collector, water collector support, water distributer& nozzles and water spray packing are
needed to be changed

for the best cooling tower manufacturer I will update this post soon
