A case study of high-temperature corrosion in rotary cement kilns by J.H. Potgieter*, R.H.M. Godoi†, and R. van Grieken† Synopsis This paper describes two cases of corrosion that occurred in dry-process, rotary, cement-clinker kilns. In the case of the kiln with five pre-heater stages, the attack occurred primarily from sulphates
Our cyclones offer higher capacity than other such systems and we have re-designed the cyclone inlet and cylindrical sections to minimize turbulence and wear. In case of very abrasive dust, we insert an internal liner to protect the shell from damage. We can design cyclones for applications such as in the cement

Nov 08, 2008· Re: Cyclones high temperatures. Our kiln capacity is 2000 t/h with feed rate 143 t/h but now we can't go more than 138 t/h. I.D fan is running with max. capacity, if we increase the feed CO & free lime increasing, liter weight & O2 dropping down and etc. Regarding to the our fuel (Natural gas) is the same quantity and quality no any changing and no any problem with our fuel.
Jul 05, 2017· Corrosion causes plant shutdowns, waste of valuable resources, loss or contamination of product, reduction in efficiency, costly maintenance, expensive over design and also can jeopardize safety. In general, corrosion in cement plants occurs when process gases containing moisture, SOx, HOI, and NOx, operate at dew point temperatures.

equipment corrosion caused by hot combustion gases in a cement plant. Summary The serious economic consequences of corrosion damage in cement plants have become a problem of global significance. Industries that are energy intensive, such as cement, often experience severe corrosion damage caused by hot combustion gases.
The cyclone is configured to accelerate the natural separation of material from air. The cyclone has no moving parts, no filters to clean, and plant air and electricity are not needed for its operation. Cyclones prove to be effective as filterless pneumatic receivers.
The corrosion is caused by Chlorine and Sulphur that are introduced to the pyro-system as impurities in the fuel and the product of reaction formed by alkali, Sulphur and Chlorine creates severe corrosion in the dip tube, thereby reducing the service life. Figure 2: Failed central tube sample received from cement plant.

Alibaba offers 606 cyclone cement plant products. About 8% of these are cement making machinery, 2% are concrete batching plant, and 2% are filter bags. A wide variety of cyclone cement plant options are available to you, such as centrifugal fan, raymond mill.
Corrosion of embedded metals in concrete can be greatly reduced by placing crack-free concrete with low permeability and sufficient concrete cover. Low-permeability concrete can be attained by decreasing the water to cementitious materials ratio of the concrete and the use of pozzolans and slag.
