A Brief Look at the Advanced Performance Inject-Aire Low NOx Burner

 

The president of the Preferred Utilities Manufacturing Corporation, David Bohn directs new product development and handles corporate revenue and growth efforts. David Bohn took the helm as president after joining the company’s Redding, CT, office and working his way up the ranks. He has spearheaded a number of projects in his leadership role, including the development of the Advanced Performance Inject-Aire (API-AF) Low NOx Burner.

The API-AF offers extensive fuel-burning capability and an impressive efficiency that significantly reduces greenhouse gas emissions and the overall carbon footprint of users. Designed to produce a stable flame regardless of firing rate, the burner can fire a range of fuel oils and natural gas. It incorporates variable-frequency drive motor controllers for enhanced control of the forced-draft fans, which in turn provides more air for combustion and results in a reduction of energy consumption.

Preferred Utilities engineers constructed the burner for use in single-burner applications, such as cast iron sectionals, watertube boilers, and high temperature hot water (HTHW) generators. Its installation at the Stapleton Houses managed by the New York City Housing Authority has contributed to prolonged boiler life, a reduced carbon footprint, and increased electrical and fuel savings. In addition, the API-AF limits NOx emissions and meets compliance standards for Local Law 87, a green building and energy efficiency ordinance set forth by the New York Mayor’s Office of Sustainability.

David Bohn and Preferred Utilities Manufacturing Corporation in Danbury, CT, present an innovation in system control for more convenience and reliability.

The great thing about the Flexible System Controller (FSC) is that each one operates as a programmable logic controller. They’re installed on every piece of your fuel delivery system, then networked together. They’re designed “masterless” so that if one goes down, the others won’t fail too.

Preferred understands the necessity of reliable technology, especially for mission critical facilities. Data Centers, for example, rely on generators as the primary source of backup power. To combat unwanted power disruptions, we designed the FSC with a dual redundant NodeNet communication network and distributed controls. These features make the FSC one of the best solutions for mission critical facilities looking to avoid costly outages.

The FSC provides the most reliable fuel oil control system for emergency power in mission critical facilities. Dual redundant cabling from each node means there’s no chance for repeater failure, hub failure, or switch failure. They’re modular, too, meaning they plug-and-play with typical fuel handling components. That includes day tanks, pump sets, filtration units, and remote fill stations. The FSC communication network also reduces the amount of wiring by 700%.

The FSC works because it distributes hardwired modular controls to each local device throughout the plant. This way, it is easy to troubleshoot from any node. The FSC communications network lets you do something you’ve never been able to do before: now you can control or view any device, status, or alarm anywhere in the system from any touchscreen in the network.

David G. Bohn is the President and CEO of Preferred Utilities Manufacturing Corporation in Danbury, CT. David has worked at Preferred Utilities for almost 30 years and gratefully follows in his father’s and grandfather’s tradition of putting quality and sound engineering at the center of every product with the promise that Preferred stands behind every application because our name is on it.

David Bohn serves as the president of Preferred Utilities Manufacturing Corporation, a Danbury, CT-based manufacturer of products for nuclear power facilities with locations in Andover, MA; New York, NY; and Redding, CT. In 2016, David Bohn and the Preferred Special Combustion Engineering (PSCE) division of his company collaborated with the Wright-Patterson Air Force Base (WPAFB) to convert two coal-burning boilers into natural-gas heating plants.

The $15.4 million project focused on modifying existing coal-fired boilers to meet newly implemented air emission regulations set forth by the US Environmental Protection Agency (EPA). WPAFB’s previous configurations for supplying steam and hot water to over 14.5 million square-feet of controlled space consumed more than 44,000 tons of coal annually, an amount that exceeded the EPA’S Maximum Achievable Control Technology (MACT) emission limits. Deadlines established by the EPA gave the Dayton, Ohio, base until January 2017 to complete conversions.

Completed in September 2016, the finished project features two natural gas–fired high temperature hot water (HTHW) generators that utilize wall-mounted burner configurations. The generators also use a unison-fired system that jointly controls fuel and air systems and inhibits individual firing. In addition to meeting standards for reduced NOx and carbon monoxide emissions, the generators achieved decreased emissions of carbon dioxide by 50 percent.

The Juvenile Arthritis Conference

Since 1995, David Bohn of Redding, CT, has led Preferred Utilities Manufacturing Corporation in his role as president. Outside of work, David Bohn gives to several charitable organizations, including the Arthritis Foundation.

The Arthritis Foundation hosts a number of events throughout the year to support individuals with arthritis. One such event is the Juvenile Arthritis Conference, which gathers hundreds of youth and families together to discuss and share information about rheumatic diseases.

The conference offers age-appropriate information sessions to reach youth of all ages. For example, the Kids & Tweens program breaks youth up into groups, where they engage in fun activities while learning how to manage their illness. The program for teens teaches high school students how to accept their condition as well as overcome obstacles. In its efforts to support entire families, the conference encourages siblings to participate and offers a program for parents to learn about the latest research and treatments.

In 2017, the Arthritis Foundation will offer two Juvenile Arthritis Conferences, one in Houston from July 13 through 16 and another in Indianapolis from August 10 through 13. To learn more, visit www.kidsgetarthritistoo.org/juvenile-arthritis-conference/2017/save-the-date.php.
