Neundorfer Purchases APCO, Expands ESP and Baghouse Knowledge and Services

Neundorfer & APCO Agreement Signing

Effective May 1, 2007, Neundorfer purchased Hopkinsville, Kentucky-based APCO Services, Inc., a leading firm in environmental consulting and specialized testing services that include in situ and laboratory dust resistivity testing, physical scale gas flow modeling, precipitator performance modeling and gas flow distribution measurements. The APCO acquisition also enables Neundorfer to expand its range of particulate air pollution control expertise to include baghouse (or fabric filter) dust collection equipment as well as consulting and technical field services. The extensive experience of the APCO staff, including founders Dr. Marlin Anderson and Jim Parsons, is now available under the Neundorfer Particulate Knowledge umbrella.

Troubleshooting: Discharge Electrode Suspension Considerations

In our last troubleshooting article, the topic was the purpose of discharge electrodes and common causes of wire failures. This article discusses suspension considerations encountered by users of weighted wire discharge electrodes.

There are two discharge electrode frames to consider in weighted wire applications:

1. Upper wire frame from which wires are hung

2. Lower wire frame which maintains horizontal stability of wires by fixing the position of the wire and its attached weight

Factoid: Isolating the discharge electrode system from grounded sections of the precipitator is essential for proper performance. Electrical clearances should be maintained at a distance near the plate-to-plate distance. With 9” plate spacing, a distance of 8 inches is usually acceptable, meaning that the discharge system structure should be no closer than 8 inches from the nearest ground source.

The most critical consideration in the design of discharge electrode systems is the alignment of components to set and maintain electrical clearances that maintain high operating voltages.

Need weighted wires? rappers?

Place your order with Neundorfer and we'll build them. (By the way, Neundorfer has sold more than 25,000 EMR2 rappers and still going strong...).


We're Listening!

Our SmartAsh customers tell us that they love the alarm and trending functions that the Neundorfer software provides for hopper evacuation systems. But...they would like it even more if we could provide recommended actions for operators to take based on the diagnostics, making it easier for corrective steps to be taken.

Based on this customer feedback, we're working on it. We expect that we can offer this solution within the next six months.

Computational Fluid Dynamics/Flow Modeling


Featured Service: Flow Modeling

Neundorfer has in-house flow modeling capabilities that include computational fluid dynamics (CFD), physical modeling and field testing. By integrating the technology of 3D graphic design, CFD and physical modeling, Neundorfer produces the most accurate output for each project.

The benefits of the Neundorfer flow modeling capabilities include:

1)  Quick turnaround of testing results as a function of Neundorfer's fully integrated capabilities allows faster implementation of improvements and quicker payback
2)  Reduced outlet emissions resulting from optimized flow through the pollution control device (i.e., ESP, FF, SCR, FGD, process ventilation).
3)  Optimized flow distribution in a precipitator in some cases yields better gains in performance per dollar spent than adding collection area or other expensive alternatives
4)  Improved flow distribution in baghouse compartments can optimize the gas flow across filter bag surface area which results in improved performance and longer bag life
5)  Reduced pressure drop which results in reduced operating costs
6)  Eliminated maintenance time and costs associated with removal of dust dropout and ductwork buildup
7)  Improved effectiveness of SO3 or NH3 flue gas conditioning and activated carbon injection


Neundorfer has the expertise to engineer, fabricate and install flow optimization modifications providing a convenient, cost-competitive turnkey solution for our customers. Our knowledge of precipitators and baghouse operations can improve the output of the flow study and reduce mistakes made in model testing.

Optimization of flow yields significant cost-effective benefits that improve the performance of electrostatic precipitators as well as SCRs, flue gas desulfurization, and process ventilation. With practical field experience, Neundorfer is the only company that provides expertise in flow modeling as well as the engineering of the modifications, fabrication or installation.

Neundorfer Training Theater

New Neundorfer Training Facility

The previous Neundorfer building (where our offices used to be) has been renovated to create additional meeting space and a state-of-the-art theater-style training room, fully equipped with comfortable chairs, a big screen and “surround sound.” The theater room can accommodate up to about 40 people and each of the tables is equipped with electrical and Ethernet connections for laptop computer and internet access. This renovation was also completed with “green building” materials and processes, as with our first renovation.

So far, the new training facility has been used for our 2007 POS Users’ Group, customer visits and training for Neundorfer people. We plan to extend the usage of this training facility to offer:

1)  Training seminars for our customers (and for employees) on topics of interest, ranging from basic precipitator and baghouse operations to systems optimization and flow modeling
2)  Collaborative training with industry partners and experts (such as the EPA) on current industry issues and events
3)  Providing the space for customers who want to conduct their own training
4)  Professional development for Neundorfer staff (e.g., project management, Six Sigma, etc.)
5)  Possible rental to area businesses needing training facilities

By utilizing our training facilities in these ways, we want to enhance our value to customers directly as well as to expose our customers and other industry partners to all of the capabilities offered by Neundorfer. If you would like to take our training survey and tell us what type of training would help you, e-mail us at info@neundorfer.com.
