6 Tips for Improved Efficiency & Reduced NOx Emissions

75,000pph Rental Boiler with Urea-Based SCR System for Single Digit NOx

Nationwide Boiler's Director of Environmental Solutions, Sean McMenamin, provided content for this month's issue of Process Heating Magazine. The topic of discussion this time around is reducing NOx emissions and improving overall boiler efficiency.

Sean has provided six tips to ensure the highest possible thermal efficiency, and lowest possible NOx output. This includes:

1. Reducing Stack Gas Temperature to Increase Efficiency
2. Managing Excess Air Levels for Optimum Performance
3. Utilizing Flue Gas Recirculation (FGR) to Reduce NOx Emissions
4. Selective Catalytic Reduction for Ultra-Low NOx Performance
5. Combining Economizers & SCR Systems for Emissions & Efficiency Gains
6. Monitoring Emissions & Efficiency Performance

For additional details related to these tips and tricks for reducing NOx and increasing efficiency, check out the full article in Process Heating's September 2018 issue!

See The DataStak Demo at Power-Gen!

Nationwide Boiler's newest innovative product - the DataStak Emissions and Efficiency Monitoring System - was highlighted in the latest issue of Today's Boiler Magazine. See the article here: goo.gl/3n2W4v

The DataStak provides boiler operators with information related to the emissions output and efficiency of their boiler systems. In today's marketplace, this data is not just something that most energy and facility engineers want to know, but many need to know this information for reporting purposes.

We designed the DataStak system to provide real-time, unified data at your fingertips, from one convenient, on-site source. It is more than just a combustion or NOx analyzer. The DataStak is a cost effective, packaged emissions and efficiency monitoring system with O2, NOx, CO, and CO2 measurements, in addition to real time boiler efficiency, fuel usage and carbon footprint calculations.

Representatives from Natiownide Boiler are in Las Vegas, NV this week for Power-Gen, the largest power generation event of the year. Experience the power of the DataStak, live and in-person at the show! Visit us at booth #6019 to learn how the DataStak can help you stay informed on how your boiler is performing.

Improving Boiler Efficiency

It is important for a boiler to run at its most efficient level in order to avoid costly issues and obtain the best results. Excess air is essential in boiler operation to minimize heat loss and improve combustion efficiency.  Here are some tips to help you make sure your boiler is running at the most efficient level possible:

  1. Periodically monitor flue gas composition and tune your boilers to maintain excess air at optimum levels.

  2. If there is a continuous blowdown system in place, consider installing a heat recovery system.

  3. If there is a non-continuous blowdown system, then consider converting it to a continuous blowdown system coupled with heat recovery.

  4. Reduce operating costs through maximizing the return of hot condensate to the boiler.

  5. If a condensate return system is absent, estimate the cost of a condensate return and treatment system (as necessary) and install one if economically justified.

  6. Repair steam distribution and condensate return system leaks.

  7. Insulate condensate return system piping to conserve heat and protect personnel against burns.

  8. Review your blowdown practices to identify energy saving opportunities.

  9. Examine operating practices for boiler feedwater and blowdown rates developed by the American Society of Mechanical Engineers (ASME). Considerations include operating pressure, steam purity, and deposition control.

  10. Consider an automatic blowdown control system.

NOx, Boilers, & Energy Efficiency Webinar, November 5, 2010 (hosted by Enovity)


This 60-minute webinar will review the NOx regulations in California's Bay Area and San Joaquin Valley. Julian Elliot, a representative from the Bay Area Air Quality Management District, will discuss how current and upcoming regulations will impact boilers in the Bay Area. The webinar will continue with a discussion on the benefits related to combining boiler efficiency upgrades with NOx compliance projects. The webinar will conclude with an introduction to Enovity's Boiler Efficiency Program and a discussion of the available rebates and incentives available for facility/plant owners.
