Boiler Solutions That Adapt to Today’s Sustainable Requirements

Nationwide Boiler, established in 1967, has built a strong standing reputation by offering reliable rental boilers to assist industrial companies in both scheduled outages and unforeseen emergencies.

Featuring a diverse inventory of more than 100 boilers across various U.S locations, our equipment spans in size from 50 HP to 200,000 lb/hr and includes mobile package watertube boilers, fully equipped mobile boiler rooms, and skid mounted systems. Over the years, our company has expanded our capabilities, evolving into more than just a world-class rental boiler company. We are a stocking distributor, a UL-certified control panel design and manufacturing facility, and we provide sustainable solutions such as electric boilers, hydrogen blended fuel firing capabilities, and our CataStak™ Selective Catalytic Reduction (SCR) System.

As our company continues to evolve, we adjust to the changing times by providing environmentally friendly alternatives within the boiler industry. This involves the utilization of SCR and ultra-low NOx burners to manage NOx emissions, along with the integration of heat pumps and alternative fuel choices for the purpose of decarbonization.

Ultra-low NOx Solutions

Our journey into sustainable solutions commenced in the 1990’s with the introduction of the CataStak SCR to the market. The CataStak is an established solution for lowering NOx and CO emissions to single-digit levels, tailored for applications with package boilers, fired heaters, gas turbines, and other fired equipment. Equipment utilizing a CataStak SCR system has yielded source test results as low as 1 ppm NOx.

Recognizing that SCR technology may not be suitable for every application demanding ultra-low NOx performance, we serve as a supplier and user providing other options like ultra-low NOx burners. Several of our mobile boiler rooms and package firetube boilers incorporate these burners to comply with emissions standards in various regions of California and Texas. Therefore, we also deliver ultra-low NOx burners for permanent requirements when the application aligns better with burner technology.

Alternative Fuels for Decarbonization

Exploring alternatives to fossil fuels offers an additional avenue for sustainable steam and energy production. These alternatives encompass hydrogen, biofuels, and electricity, preferably sourced from renewable sources.

A preferred electric approach for high-pressure steam generation involves the use of electric boilers. Leveraging electricity as a clean, efficient, and easily controllable fuel, every unit of energy input into the boiler is converted to steam with an efficiency of 99%. Numerous industrial facilities possess the required power infrastructure to support an electric boiler, rendering it an optimal zero-emissions solution. Nationwide Boiler’s in-stock electric boiler packages are available for both rental and permanent applications.

Heat pumps are also a favored option for electric heating in comfort applications and, with ongoing technological advancements, are now being applied in industrial settings. Although heat pumps may not currently produce high-pressure steam, they can contribute to industrial processes by providing heat up to 240°F. Also, a heat pump is significantly more energy-efficient, utilizing only about one-third of the energy compared to traditional electric or fossil fuel heat-generating equipment for achieving the same temperature increase.

Lastly, hydrogen and biofuels are now being utilized more frequently as an environmentally friendly alternative to the prevalent use of natural gas or fuel oil in steam boilers. Hydrogen, a proven and low-emission fuel in the boiler industry for several years, offers virtually no carbon emissions. With experience and expertise in hydrogen and biofuels, our engineering group has confirmed that Nationwide Boiler’s existing fleet of package watertube rental boilers can effectively use blended fuels containing up to 20% hydrogen, with no need for system modifications. Originally designed to accommodate natural gas firing, this adaptability is made possible by our strict rental boiler construction standards, which integrate high-quality and robust components such as valving, fuel trains, burners, and more.

Drawing from our extensive history and the collective years of industry experience, our team is dedicated to providing trustworthy temporary rental boilers, sustainable solutions for steam generation, and more, all guided by the principles of "Integrity, Dependability, and Real Customer Service."

Proposed Rule for Greenhouse Gas Emissions

The EPA today proposed a new reporting ruling that would require large, direct emitters of greenhouse gases to comply with new reporting requirements. These would include energy intensive sectors such as cement production, iron and steel production and electricity generation.

EPA Administrator Lisa P. Jackson realizes the importance of gathering critical data in order to better understand climate change for a healthier future.  She notes that this proposed requirement will not affect small businesses, but is rather aimed at large businesses, those that have emissions equal to or greater than a threshold of 25,000 metric tons per year.

"Our efforts to confront climate change must be guided by the best possible information. Through this new reporting, we will have comprehensive and accurate data about the production of greenhouse gases. This is a critical step toward helping us better protect our health and environment - all without placing an onerous burden on our nation's small businesses."

The EPA estimates that the expected cost to comply with the reporting requirements to the private sector would be $160 million for the first year. In subsequent years, the annualized costs for the private sector would be $127 million. This rule is being developed under the authority of the Clean Air Act and the proposed rule will be open for public comment for 60 days after publication in the Federal Register. Two public hearings will be held during the comment period.

Nationwide Boiler's low NOx solutions are developed for companies, large and small, who want to do their part in combating climate change. We have upgraded our fleet of rental boilers with Low NOx equipment in order to easily meet emissions requirements in any part of the county. For those customers wanting even lower emissions our CataStak SCR systems have been proven to reduce NOx emissions below 5 ppm in over 50 installations and that list continues to grow.

Nationwide Boiler is ready to help your facility meet your "green" goals. Contact us today and let us know how we can help.

"Low Hanging Fruit" Efficiency Choices

Every week we receive a lot of information on energy efficiency solutions and updates about what the government is doing about climate change. Earlier this week we attended the 18th annual luncheon of the Manufacturers Council of the Central Valley, a group based in Modesto, CA which represents the interests of local manufacturers.

The Keynote speaker, Dorene D'Adamo, a member of the California Air Resource Board, discussed climate change, California's emission reduction goals, and strategies aimed to help meet the state's emission reductions by 2020. One thing mentioned that struck a common chord among others in our industry was the idea of "low hanging fruit" - remedies that are currently being developed and utilized that make a notable difference in reaching energy efficiency and emission goals.

This concept was also recently expressed to us by Sid Abma of Sidel Systems. Sid mentioned that the easiest and most highly promoted action we, as a society, do to help curb greenhouse gas emissions are on the side of electricity reduction and conservation. This includes changing light bulbs, insulating our attics, double panning our windows, and using electric motors.

Sid states that everything we read and hear is about being power smart (electricity). Renewable energy such as solar, wind and tide are also on the fore front, but it always seems to circle back to electricity. Sid argues that emission reduction strategies from natural gas usage are often ignored. Natural gas is widely used in industry (food and beverage, textiles, electricity generation, pharmaceuticals, chemicals, rubber, plastics, etc.) and reductions in its usage need much more attention than it is currently receiving.

We agree with Sid. The mainstream media's focus is often times more focused on "low hanging fruit", however, we have also seen great strides from the government and public utility companies in terms of promoting energy efficiency and offering rebates and incentives for industry users. For example, the U.S. Department of Energy's Industrial Technologies Program (ITP) leads the nation in conducting research and development for energy efficient technologies and supports the commercialization of emerging technologies. In addition, the EPA provides guidance and recognition to companies that develop long-term climate change strategies through their "Climate Leaders" program. Locally, many of our users have worked with PG&E and third party vendors to obtain rebate checks from equipment upgrades, which have resulted in substantial energy savings.

Sid's energy savings solution towards natural gas is condensing flue gas heat recovery. The Sidel SRU Series Condensing Flue Gas Heat Recovery Unit can be installed with any natural gas fired power boiler or heating unit. It is designed to reduce operating costs by recovering much of the wasted heat normally lost in the atmosphere into usable heat. Potential applications for the recovered heat include preheating process water or preheating return water for heating systems or boiler make-up feedwater. More specially, schools, universities and hotels could use the recovered energy for swimming pool water or it can be used into the space heating systems of buildings. Sidel System's website includes additional information about this cost savings solution, and if you have not already researched this topic, it is worth a look.

We all know that increased natural gas energy efficiency will reduce greenhouse gas emissions. There are many ways that this can be achieved and advancements in technology are always evolving.  Today, we must open our eyes a little wider and pay attention to all the cost-saving opportunities available at our fingertips that are not always widely recognized. The low hanging fruit is not only the easiest to pick, but it is often times the most ripest.

We would like to know what you are doing to reduce your natural gas usage. Also, are there any emission/energy reduction strategies you feel are not getting the attention they deserve?
