Scheuch EMC Technology Improves Plant Operations


When a global cement company was experiencing a high-pressure drop across the clinker cooler baghouse as well as ineffective cooling in the clinker cooler heat exchanger at one of its North American plants, it reached out to Scheuch for help. The customer was familiar with Scheuch EMC technology, as it utilized the technology at other plants globally, but previous to this project, none in North America.

Scheuch long-bag filter technology provides maximum filtration in a small footprint.

Scheuch’s engineering team developed a two-year project implementation plan that fit within the plant’s operating schedule and capital budgeting process. In the first year, a new Scheuch EMC baghouse would be installed, tackling the immediate need to reduce the elevated pressure drop. The long-bag filter technology would be used to provide the maximum filtration area in a smaller footprint; making installation in the existing plant easier. In year two, the heat exchanger would be retrofitted with new Scheuch heat exchanger components, including bundled, staggered row heat exchanger tubes and Variable Speed Drive (VSD) controlled axial-flow fans for more effective cooling.

Ultimately, the customer purchased an EMC baghouse for the clinker cooler exhaust, heat exchanger and auxiliary material handling equipment, including Scheuch screw conveyors. In fact, the customer was so impressed with the Scheuch screw conveyors, they were purchased for applications outside of the baghouse scope of work.

Immediately following the installation of the baghouse, the customer realized an improvement in pressure drop of nearly 12 mb. In the following year, after the heat exchanger was installed, water injection volume in the downstream process was significantly reduced, thus resolving processing issues.

Another EMC collector and heat exchanger were purchased for the main baghouse at the same facility a few years later. The customer now has a total of seven Scheuch EMC baghouses in two facilities in the southeastern United States.
