A New Way to Analyze Fan Systems for Optimal Performance and Cost Savings
Most fans designed to provide critical ventilation in commercial and industrial facilities have been carefully tested by manufacturers to meet industry standards. Yet despite conscientious testing and precisely calculated ratings, many fans do not operate as anticipated after they are installed. This leads to system inefficiencies and a de-rated system that may affect production and increase costs. A phenomenon known as “system effect” helps to explain the myriad reasons why a fan that performs optimally in a laboratory might not perform as well in a facility. This gap in fan performance exists in large part because a laboratory’s ideal conditions cannot replicate the countless configurations and conditions under which a fan will operate in a live facility setting.

Water Treatment for Steam and Boiler Installations
As concerns about global warming increase, so do pressures to reduce energy consumption and increase efficiency. Boiler manufacturers have responded by making more sophisticated and complex equipment built to tighter standards, which has made water quality an ever-increasing issue. This article provides guidance for applying water-treatment programs in conjunction with new steam- and hot-water-boiler installations.
Maximizing ‘Temporary’ Connections for Future ReliabilityWhen the time to replace boilers comes, temporary boilers often are needed to support the steam load. Services from and to boilers, including fuel, feedwater, electric power, and steam, have to be provided according to code, regardless of the fact the services are “temporary.” Forward-thinking building owners recognize the value in the connections, not as nuisance pipes and conduit, but as hard points where a temporary boiler can be rapidly connected. Temporary boilers can be on site in as little as 24 hours, but how long would it take to provide the connections necessary to run the boiler? This article will discuss the technical elements associated with providing boiler services, choosing connections to maximize reliability, and finishing temporary connections so they are ready for future use.Proper Procedure for a Boiler-Room AssessmentA boiler-room assessment can help a facility increase its efficiency, sustainability, reliability, and safety. To be done right, a boiler-room assessment requires a specific methodology and expertise. The starting point is determining a facility’s loaded steam cost, which many people calculate incorrectly. Conducting an assessment and implementing the recommendations ensures a facility’s boiler system operates optimally.Selective-Catalytic-Reduction-System Considerations for Highly Effective NOx Reduction and ControlSelective-catalytic-reduction systems have been proven to be the most effective and flexible method of NOx reduction and control for fired equipment such as boilers, heaters, incinerators, and gas turbines. For these systems to be highly effective and flexible, the owner and supplier must have an equal understanding of the functionality of the equipment in the plant. This article will share key design criteria and options to meet a variety of emissions-reduction targets.Tankless Water HeatersThis article will discuss how tankless water heaters can help building owners increase return on investment, energy savings, and uptime reliability. Among the topics to be covered are the economic, size, safety, and life-cycle benefits of tankless systems. Applications such as hospitality, health care, education, and multifamily buildings will be discussed as well. .Design Solutions: Wrigley Yorkville-Plant ExpansionTo accommodate Skittles production, Wm. Wrigley Jr. Co. is investing $50 million in a 145,000-sq-ft expansion of its Yorkville, Ill., plant. This article will discuss the selection of boilers for the project.Design Solutions: Cogen at Ronald McDonald House New York CityAt Ronald McDonald House New York on Manhattan’s Upper East Side, the boiler and chillers were in need of replacement. After two years of research and data collection, on-site cogeneration equipment was determined to meet the heating, cooling, and domestic-hot-water loads while supplying 95 percent of the building’s power needs. A natural-gas-fired IntelliGen combined-heat-and-power unit, three 50-ton Yazaki absorption chillers, and a pair of Laars NeoTherm condensing boilers were installed as part of the project..Product Spotlight: Boiler Systems
