Effective Rapping. Lower Baseline Emissions.

As much as 30% of your baseline emissions is likely attributed to rapping. This is particulate that had already been collected and then was swept back into the gas stream when rapped. Optimizing rapping to mechanical area, load, resistivity, opacity, and other process variables can drastically reduce outlet emissions. Our rapping system solutions can include complete rapping system upgrades, rapper control upgrades, replacement parts, and upgraded rapping system components and rappers.

Rapping System Upgrades

We offer reliable, easy-to-install rapping systems for plate and discharge-electrode cleaning that will increase precipitator power and reduce dust re-entrainment, which ultimately reduce stack emissions. We can design systems to improve rapping density, or to improve rapping energy transmission. Importantly, we will design a rapping upgrade that will optimize precipitator performance, meet your emissions requirements, support your operating strategies, and stay within your budget. We can do this because we know, and can model, the performance, cost, and flexibility trade-offs within these project decisions. Bring us your challenge. Our team of engineers and air pollution control specialists are passionate about collaborating with customers to reduce costs and improve performance through simplistic innovation.

We offer both Neundorfer EMR Impact magnetic lift rappers as well as NAVCO Rappers. Neundorfer EMR Impact rappers feature a slip-on mount construction for easy installation and an integrated fiberglass guide tube and coil guide to extend wear capabilities. These magnetic-lift, gravity-impact rappers are easier and less time-consuming to install and offer a universal fit for any OEM precipitator design. Their reliability, along with the MicroRap rapper control, lead to increased precipitator power and efficiency.

NAVCO pneumatic rappers set the standard in the industry for performance, reliability, and dependability. These rappers are ideal for applications where repetitive-impact rappers are needed and are highly reliable in all climate conditions.

Rapping System Components

We offer steel or ceramic rapper shafts, adapters and sockets, and rapper shaft seals. We also offer rapper controls, and supervisory software that can automatically adjust rapping based on precipitator or process conditions.

Upgraded Granular Sulfur Feeder More Effective Than Molten Sulfur

Duke Energy's Allen Station: SO3 System Upgrades

When Duke Energy's Allen Steam Station started upgrades to the granular sulfur feed system for three of its units, the utility partnered with Neundorfer to reduce emissions and improve reliability. ...
