Boilers equipped with condensing economizers can have an overall efficiency that exceeds 90 percent. A condensing economizer can increase overall heat recovery and steam system efficiency by up to 10 percent by reducing the flue gas temperature below its dew point, resulting in improved waste heat recovery.
The key to a successful waste heat recovery project is optimizing the use of the recovered energy. By installing a condensing economizer, companies can improve overall heat recovery and steam system efficiency by up to 10 percent.
At first, the call sounded like one we hear all the time - not enough heat in a room that had been added onto a house. The service guy told me the radiators were big enough, and that the house had an old gravity hot water system. He asked if I’d stop by to look at it.
Facility managers of the future will be astonished when they
discover that building systems were not always integrated into a
single enterprise-wide information technology network.
Yes, the “old days” of operating a building will be compared to writing letters
instead of text messaging. This future scenario is a lot closer than it seems.
Some applications utilize
an input or supply voltage of 277-1-60. While some components are
available for direct application of 277-1-60 power, most manufacturers find that the use of a buck-boost transformer to
lower the voltage is more cost effective.
Ask
many school administrators about the air quality inside their buildings, and
the frank answer is liable to be “Well, we don’t know.”
They should. School
air quality and student performance go together as naturally as breathing in
and breathing out.
Building automation systems (BAS) have made
great strides toward embracing connectivity and
interoperability standards. This has given building owners more
freedom to choose among manufacturers for products and service support.
Even greater benefits await an organization whose BAS is merged with information technology.
In this article, the author describes a proactive
HVAC replacement program instituted at Limited Brands Inc. that is all
about doing the right thing economically
and effectively.
This article explains the Occupational Safety and Health Administration (OSHA) standard for control of hazardous energy sources, why this is important, and what employers must do to protect their employees.
Some utility companies and public agencies have rebate programs in place to encourage customers to upgrade their existing standard-efficiency motors to NEMA Premium™ efficiency motors. Yet, to accurately estimate energy savings and determine annual dollar savings requires knowing the efficiency of the existing motor.
