Decarbonization: What Does it Mean for the Rental Boiler Industry?

Decarbonization relates to the reduction or ultimately the extinction of greenhouse gas emissions released into the atmosphere. According to the EPA, Carbon Monoxide (CO2) makes up the vast majority of greenhouse gases released during the combustion of fossil fuels. In addition to CO2, smaller amounts of methane (CH4) and nitrous oxide (N2O) are also emitted during the combustion process. With majority of rental boilers being natural gas or oil fired, what does this mean for the future of rental boilers?

With over fifty years in the industry, Nationwide Boiler has excelled through similar hurdles. In 1995, we became the first and only rental boiler company to convert our entire fleet of watertube boilers to low NOx levels of 30 ppm. In 2001, we started actively utilizing our CataStak™ SCR system on package watertube rental boilers for ultra low NOx compliance, and in 2011 we developed the product further announcing the ammonia-free / urea-based CataStak™ SCR. These and other initiatives were accomplished with sustainability and environmental improvements in mind.

While our CataStak™ and EconoStak fuel efficiency products help the environment by reducing tons of greenhouse gas emissions, we realize the need to consider an alternate non-fossil fuel with the potential to replace the “transitional” fuel of natural gas. Luckily there are some alternate energy solutions available today, including bio-fuels, hydrogen-fired, solar, hydro, and electric.

One thing we know for certain is that the current production of steam cannot be displaced easily or quickly with these alternative energy solutions. Steam as we know it is used not only for heating, but for producing many everyday products like food, beverages, paper, plastics, pharmaceuticals, chemicals, gasoline, textiles, and electricity, to name a few.

With this growing move away from the use of fossil fuels and in California specifically, Nationwide Boiler has added an electric boiler to our rental fleet – and it is our intention to add more in the future. This provides an option for customers with excess electricity available, and a solution for customers wanting a zero emissions alternative. Our first electric boiler system has been built to provide 50 hp steam at operating pressures up to 150 psig. The system includes a factory integrated, pre-piped and wired duplex feedwater system, blowdown separator, and single-point electrical POC calling for a 480 VAC, 3 phase, 60 HZ power supply. It is a smaller package than our standard fuel-fired mobile steam plants, and it requires a much smaller available footprint for installation.

In addition to adding electric boilers to our rental fleet, Nationwide Boiler is now a California representative for Precision resistant type electric steam boilers as well as Vapor Power electrode steam boilers. We can provide new, zero-emission boiler packages to facilities interested in pursuing a non-fossil fuel fired, steam boiler alternative.

As a company, Nationwide Boiler vows to continue to identify and assess alternative and sustainable options to help improve the environment while providing the reliable steam necessary for the many industries we serve today.

Boiler Basics 101: Economizers for Increased Efficiency

The price of fuel is constantly fluctuating and with it comes creative ways to be more economical. Finding methods to be more energy efficient is never a waste of time. In the boiler room, efficiency improvements can be found by many sources, however, a common option for energy savings includes the use of an economizer. What is an economizer? The economizer is a fabricated assembly of finned tubing that captures waste heat extracted from the boiler’s stack flue gases; the exhaust that leaves the boiler stack (or “flue”).

It’s all about the principle of Heat Transfer. While low temperature water, or feedwater, enters a boiler system, high temperature flue gas exits. An economizer captures heat from the flue gas that would typically go to waste, and utilizes it to preheat the feedwater. By doing this, an economizer is able to increase thermal efficiency by decreasing the energy required to heat the water to steam. This will typically result in a reduction of 1% in fuel cost per 10 degree rise in feedwater temperature. Overall, an economizer can be a major cost savings for boiler owners and will easily provide a quick return on investment.

The economizers’ simple technology and static parts provide longevity and low maintenance, and they are available in multiple designs and configurations. Conventional economizers are cylindrical or rectangular and come in a range of sizes for both firetube and watertube boilers. Rectangular designs are more commonly used for larger industrial watertube boilers, and can be configured for vertical or horizontal gas flows, finned or bare tube design, and other additional options if needed. A condensing economizer can improve waste heat recovery even further by cooling the flue gas below its dew point, reclaiming both sensible heat from the flue gas and latent heat by condensing the flue gas water vapor.

BOILER EFFICIENCY COMPARISON
  Combustion Efficiency at
4% Excess Oxygen
Stack Gas
Temperature
 Boiler  78% to 83% 350F to 355F
 Boiler with Standard Economizer  84% to 86%  250F to 300F
 Boiler with Condensing Economizer  92% to 95%  80F to 150F


When determining whether an economizer is ideal for your boiler equipment, the location of the economizer into stack is important. To ensure the most thermal recovery during the process, you need to make sure the economizer is installed as close to the furnace breach as possible. This will help avoid thermal loss and cooling.

At Nationwide Boiler, we offer our EconoStak economizer as an optional addition (or a standard addition in some cases) on our fleet of watertube rental boilers. The EconoStak consists of the economizer as well as all of the associated piping and structural supports required for very efficient and safe operation. In addition, we are a West Coast representative for E-Tech Heat Recovery Systems, a leading provider of economizers for new, replacement, and retrofit applications.

Contact Nationwide Boiler today to see if an economizer is the right option for you, and be sure to check out our previous Boiler Basics 101 blogs. We review various topics each month, so stay tuned for the next edition!

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.
