Technical Tips


ESP Technical Tip

Optimizing Your Precipitator, One Step at a Time


Optimizing the performance of your power plant's precipitator might seem like a daunting task. Ever feel that there just isn't money, expertise or manpower to achieve meaningful results? This technical tip is the first in a series focused on realistic modifications that result in the biggest bang for your buck.


The most effective performance improvement projects start with evaluating what needs fixing, and then using performance prediction tools to take the guesswork out of optimization. With this phased approach, you'll find out what will make the biggest difference: internal upgrades, gas flow modifications, process improvements, or a combination of these. 


Step one: collect data about your ESP’s design, internal and gas flow distribution components, fuel and ash composition, and stack test results. Together, these pieces of information provide a baseline picture of ESP performance. You can then use computer-generated and physical models to explore the cost-benefit tradeoffs of different options. 


This time of year, it's likely that an upcoming planned outage is on your mind. How do you make best use of this time? Some urgent repairs are no doubt needed, and you can't ignore them. However, if there is time and manpower, a physical inspection of the ESP is an excellent investment of resources. The information gleaned from such an inspection often makes the difference between upgrades or modifications that hit the mark, and those that don't. After all, knowledge is power. (See the "Don't Go It Alone" section later in this newsletter for more about internal inspections.)

Baghouse (Fabric Filter) Technical Tip

How Ammonia Slip Affects Your Baghouse


Many coal-fired utility boilers now use Selective Catalyst Reduction (SCR) or Selective Non-Catalytic Reduction (SNCR) to reduce Nitrogen Oxide (NOx) emissions. Ammonia and urea are common reagents used in SCRs and SNCRs to enhance the reaction and boost the removal of NOx. As with most additives, the right amount is okay but too much can have downstream ramifications for other equipment, such as the baghouse.


Even the most efficient SCR or SNCR system will experience a little bit of ammonia slip. But, when it becomes excessive, problems begin to occur as the dust becomes sticky. Back-end cooler compartments are typically where problems first occur. For example, when load is reduced and gas temperature drops to the dew point, dust becomes difficult to remove from filter bags.


Sticky dust results in ineffective cleaning, which snowballs into other issues: high differential pressure, increased cleaning frequency, shortened bag life. To avoid these problems, we recommend monitoring your bypass slip closely, especially at end compartments. Staying on top of this will prevent a lot of headaches.

Don't Go It Alone


Planned Outage: Help is Just a Phone Call Away


Outage season is upon us again. Don't panic; the team at Neundorfer is available to help. We'll go even further and say that consulting and troubleshooting form that foundation of our approach to optimizing air pollution control systems. That's because, instead of just treating symptoms, we get to the root cause of system performance issues.


Often, this troubleshooting process starts with a physical inspection during an outage. Our experts can come to your site, perform the inspection, and follow up with a report detailing recommended improvements. (By the way, we also continue the process by helping you make suggested changes.) Or, we can help out with the daunting task of planning how to best use your outage time. Or, we can simply provide spare parts for repairs you're expecting to make during a planned outage.


Don't go into your next outage feeling overwhelmed. Give the Neundorfer experts a call: (440) 942-8990.





Upcoming Neundorfer Training Events


Eye on the Future: Strategic Planning Workshop


What: Strategic Planning Workshop - Improving Efficiency, Availability & Environmental Impact.

When: April 27 and 28, 2010.

Where: Neundorfer training facility in Willoughby, Ohio.

Who: Managers and decision-makers aspiring to improve plant efficiency, unit availability, emissions and safety.

How much: $1,200 (includes learning materials, breakfast, lunch and beverages).


This special learning event is designed to help managers create a holistic plan for optimizing inputs and outputs, resulting in improved performance and reduced emissions. You'll gain practical, high level insights into optimizing your plant, from the coal pile to the stack.


Experts from Storm Technologies, United Dynamics Corporation, David N. French Metallurgists and Neundorfer Particulate Knowledge are hosting this event, presenting sessions on maximizing steam generator performance, optimizing boiler availability, and capturing pollutants more efficiently.


Learn more and register here. Space is limited, so make sure to reserve your seat now!






Learning Opportunity: Precipitator Users' Group


What: Precipitator Users' Group (PUG) Seminar and Labs.

When: May 24-27, 2010.

Where: Neundorfer training facility in Willoughby, Ohio.

How much: $1,400 for PUG, $150 per lab (two are offered).

Why: Make an investment in real-life precipitator management skills by attending this hands-on learning event.


Neundorfer's annual Precipitator Users' Group (PUG) seminar is fast approaching. Attending PUG is an excellent investment that results in immediate payoff when you return to your plant. PUG's focus is on learning by doing: you'll apply precipitator management concepts to real life scenarios. This year we're enhancing the experience by offering two optional, 1/2-day lab sessions for novice and intermediate users of Neundorfer Precipitator Optimization System (POS).


Registration fee includes learning materials, meals and a social event. If you sign up for PUG and one of the labs we'll give you a 15% discount on both. Don't miss this opportunity to learn skills you'll apply right away on the job. Plus, you can earn up to 15 hours of professional development credit (depending on guidelines for your state).



Have Specific Training Needs? Neundorfer Can Help!


Many electrical generation plants are feeling the pinch of a reduced knowledgebase related to maintaining and troubleshooting air pollution control equipment. If this describes your facility, call Steve Ostanek, (440) 247-0460, or fill out a training needs worksheet and send it to Maggie Zeller,


Our team of experts offers decades of experience with everything from ash resistivity issues to gas flow distribution problems to short fabric filter bag life.
