Emission control & air dedusting for steel and ferrous alloys

by Advanced Cyclone Systems, S. A.     based in Porto, PORTUGAL

teel and ferrous alloys production happens in industrial manufacturing processes which involve high temperature exhaust streams, often at more than 900 ºC. Typically, the gas flows into a gas conditioning tower to cool down to approximately 200 ºC, before entering into an ESP. These flue gases from steel or ferrous alloys kilns are also very maintenance demanding for bag filters and the very small size of the particles limit the use of usual dedusters such as regular cyclones and multicyclones as pre-separators. Bag filter failure is consequently a very common problem for clients in this industry. 

Client`s needs include a very robust dedusting system, either serving as end-stage collector avoiding the need to cool down flue gases, or strongly minimizing the loads of aggressive material to bag filters. 

Air dedusting for clinker cooler

by Advanced Cyclone Systems, S. A.     based in Porto, PORTUGAL

e control of clinker fines emissions after the heat exchanger, placed downstream of the clinker cooler is usually a problem for plant managers. The process is characterized by high material abrasiveness, high loads and variable flow rate in normal and maximum conditions.

The usual dedusting arrangement is achieved through a bag house which is typically associated with high maintenance costs and downtime in production due to frequent filter element replacements.

Emission control & air dedusting for fuel oil boilers

by Advanced Cyclone Systems, S. A.     based in Porto, PORTUGAL

For PM emission control in high temperature exhaust streams, such as fuel oil boilers, usual dedusters such as bag filters are very maintenance demanding. Particularly, diesel and fuel particulates are very sticky and clog to filter elements, unless protection reagents are used. Flue gas cooling is also needed in front of the filter when temperatures are higher than 200 ºC. On the other hand, regular cyclones and multicyclones are frequently not able to reduce emissions to present emission limits.
