Preferred Utilities Provides Power to Abington Memorial Hospital during Storm

When Winter Storm Derby knocked out power across much of Pennsylvania, Abington Memorial Hospital continued operating thanks to emergency back-up generation systems provided by Preferred Utilities Manufacturing Corporation.

Danbury, CT — Power outages caused by Winter Storm Derby forced Abington Memorial Hospital to rely on emergency back-up systems. Thanks to the emergency fuel systems provided by Preferred Utilities Manufacturing Corporation, the outage did not affect care and the hospital remained fully staffed throughout the storm.

Dr. John J. Kelly, hospital chief of staff, told local news, “We’re in good shape.” When most local schools and residential complexes found themselves without power, the Abington Memorial hospital continued its critical mission thanks to its emergency generation back-up plan.

According to NC10.com, PECO Energy, the largest power provider in the Philadelphia region, assessed Winter Storm Derby as the worst winter storm outage ever. At the height of the storm, more than 600,000 customers were without power.

Dr. Kelly explained that the hospital found itself in good shape because it had planned for contingencies during events such as snow storms. In the event of lost power, the hospital knew that it needed an emergency generation system that would work in a time of need—because for a hospital, the availability of electricity can be the difference between life and death.

In order for emergency generators to work properly, they needed a reliable delivery system to keep the fuel oil pumping during emergency situations. Abington Hospital was well

prepared for such an emergency situation thanks to a series of fuel oil products provided by Preferred Utilities, including: underground storage tanks, tank gauges, pump sets, day tanks, and boiler fuel delivery systems.

The underground storage tanks keep large amounts of backup fuel ready in case of emergencies. The pump sets provide fuel to the day tanks, where back-up fuel is ready at all times.

For mission critical applications such as emergency diesel generators and dual-fuel boilers, Preferred recommends that at least four hours-worth of fuel is immediately available via the Day Tank without activating the transfer pumps below. Abington Memorial Hospital utilized such a standby back-up fuel system.

Thanks to these products, Abington Memorial Hospital continued providing critical care to local residents during the storm—and they did so with full confidence that their fuel oil system would work when they needed it most.

When thousands of exhibitors and visitors descended on New York City for the 2014 AHR Expo, many of them weren’t prepared for the sudden snow storm that blanketed the streets of downtown Manhattan.  Preferred Utilities, however, came well prepared–and stirred quite a buzz by bringing several big items to the big apple.

Preferred Utilities debuted its new Advanced Performance Inject-Air Low NOx Axial Flow Burner (API-AF). This burner includes Preferred’s first packaged burner unit for 4MMBTUH-20MMBTUH applications.

Preferred Utilities also made a splash with its new Waterproof Pumps – an innovation spurred by Hurricane Sandy. The flooding in areas like New York and New Jersey emphasized the need to rethink mission critical infrastructure. Preferred developed the Waterproof Pump to operate uninterrupted during flood events, ensuring the safe supply of fuel for emergency generators and boilers.

Side panelFood Processing Plant Saves Money by Burning Alternative Fuel

 

Many processing plants produce large amounts of waste water, causing plant owners to rethink their energy use strategy. In 2013, a mid-western US food plant found a way to use its own waste water as an alternative energy source.
When the city of Janesville, WI began constructing an anaerobic digestion system at its waste water treatment facility, the city created a contract to sell conditioned biogas back to the food plant.
Using its own conditioned biogas, the food plant unlocked the ability to burn self-produced alternative fuel. But in order for the project to be a success, the plant needed a combustion system capable of handling such a unique demand. Based on prior success with a similar plant., the plant owner’s turned to Preferred Utilities and a team consisting of Leidos Engineering, LLC and American Boiler.

 

Preferred Utilities designed and supplied a complete combustion system, including an API-800 Burner, a bio/natural gas mixture piping train, and a proprietary burner management/combustion control system.
The system was designed to burn either natural gas alone, or a mixture of preferential biogas and supplemental natural gas. Because digester gas contains sulfur and water, Preferred fashioned 316 stainless steel for all burner and piping components to resist corrosion. The combustion system’s startup and operation procedure is governed by a BurnerMate TS burner management/combustion control system.

 

The system consists of Preferred Instruments DCS-III digital controllers and a GNE 5004-M-85 Flame Safeguard module. The plant now employs a full metering combustion control strategy with FD fan, VFD control, and oxygen trim. The combustion air demand is determined based on the sum of the combustion air requirements established by the inputs of both the natural gas and biogas flow rates.

 

The combustion system now fires a natural gas/biogas mixture, with priority given to biogas based on availability established by supply pressure, thus maximizing fuel cost savings for the food processing plant.

Boiler Controls Upgraded for Efficiency, Flexibility, and Reliability

 

Ford Motor Company sought to upgrade its burner management and combustion control systems at its research and engineering powerhouse in Dearborn, MI.

With the support of local representative D.J. Conley Assoc. Inc., Preferred Utilities upgraded several multi-burner boilers from manual to automatic firing rate control within the guidelines of NFPA 85.

 
Originally a 4-burner manual system firing natural gas, Preferred’s PLC-based BMS, PCC-III controllers, and DCS-III Controllers now allow for successive burners to be automatically lit-off or stopped based on load demand. Sequencing of burners is now made by way of a burner firing order” selection screen.

Furthermore, operators can now choose either Warm-up or Hot Standby mode. Warm-up mode holds one or two burners at low-fire until the boiler reaches its minimum flue gas temperature. Once reached, the firing rate and additional burners will light-off or shut down based on load demand.

Hot Standby holds one or two burners in the same manner, but once the flue gas temperature is met, the burners shut down and the boiler is tripped.

Preferred provided more upgrades, including dual 15-inch touch screens, “igniter only” mode and sequencing flexibility for operators. A fully-metered, cross-limited fuel-air ratio control with FD fan VSD and Oxygen Trim control provides for improved combustion efficiency. 3-element feed water and 2-element draft controllers provide for reliable operation.
