Schebler Chimney: Code Changes Impacting Grease Duct Selection

October 7, 2009
Not a lot has changed in the world of commercial grease ducts in the past few decades. Same goes in the industrial boiler realm. But recent code revisions and emerging attitudes toward energy efficiency are making an impact on specifications.

Electro Static Technology: Shaft Grounding - Fulfilling the Promise of Variable Frequency Drives

October 7, 2009
With the rising cost of energy, the use of variable frequency drives (VFDs) is growing at an increasing rate. By optimizing the frequency of a three-phase alternating-current (AC) induction motor's voltage supply, a VFD controls the motor's speed and torque while providing energy savings. And, these energy savings can be quite substantial - 20% or more - making VFDs a "green" solution as well as a wise money-saving investment.

Steam Accumulators and Steam Boiler Response to Load Changes

September 18, 2009
Steam load management is often neglected during the design phase of a steam delivery system. As a result, in the case of a boiler that serves steam-using equipment that cycles like an autoclave or sterilizer, steam quality and quantity at start up may suffer significantly. Understanding the significance of the events inside and outside the boiler pressure vessel during a rapid steam load demand period and choosing the correct design enhancements will reduce the consequences of rapid depressurization.

Maximizing Heating System Gains with Hybrid Boiler Plants

September 18, 2009
A hybrid boiler plant is defined as a hydronic heating plant combining condensing and noncondensing boilers. This system is designed to take advantage of the best properties of both boilers. Through the proper design and selection, 100% of the potential energy savings can be realized with a possible installed cost savings of one third to one half of the cost compared to an all condensing plant.

ECO-MAX Adsorption Chillers for Global Cooling

August 17, 2009
Adsorption chillers are driven by hot water rather than by large amounts of electricity like conventional air conditioners. This hot water may come from any number of industrial sources, including waste heat from industrial processes, prime heat from solar thermal installations or from the exhaust or water jacket heat of a piston engine or turbine. Organizations that could benefit from adsorption chillers include food and beverage processing; chemical, plastic, rubber, paper and cement manufacturing; hospitals; hotels; and school campuses.

Humidity Delaying Filter Maintenance: How Much is it Costing You?

August 17, 2009
Regularly changing filters may not be high on your agenda. But when you look at how much intentionally or unintentionally delaying filter maintenance is costing you in terms of increased energy use, it suddenly becomes much more important.

Leveraging BIM for Energy Efficiency

June 9, 2009
It’s out there. The need to create more environmentally conscious, sustainable buildings isno longer a noble desire, but a dire necessity. Within this historical and industrial context, it hasnever been more important to precisely understand the progressive process of designing forsustainability and energy effi ciency.

Best Practices for Power Equipment Startup

June 9, 2009
In order for the electrical power distribution systems within data centers and related facilities to operate properly as designed and intended, it is extremely important that care be given to the commissioning and startup of the electrical equipment via effective and reliable methods. This paper describes the need for a systematized program for new power equipment startup and the best practices and pitfalls that exist with regards to power equipment startup. This paper will also provide an overview of important items and issues that should be focused upon as part of reliable power equipment start up procedures and processes.

Managing Extreme Heat: Cooling Strategies For High-Density Systems

April 20, 2009
As computer manufacturers pack more and more processing power into smaller packages, the challenge of data center cooling becomes more complex - and more critical. New servers and communication switches generate as much as ten times the heat per square foot as systems manufactured just ten years ago.. As these new systems are installed alongside previous generation systems, they create hot zones within the data center that cannot be effectively managed using traditional approaches to cooling. New strategies and technologies must be implemented to provide the cooling high-density systems require for reliable operation.
