  • Case study - Air-to-air heat exchanger provides plant heat and big savings

    OVERVIEW A food processing facility installed a new Regenerative Thermal Oxidizer (RTO) for odor control from its roasting operation.  The oxidizer was designed for 95% thermal rate of efficiency and included supplemental fuel injection (SFI) which is used during low VOC loading conditions, to help save fuel cost.  The customer was looking at additional ways  to further ...

  • From air conditioning to urban planning, defaults and standards create dysfunction by design

    How can we stop outdated assumptions from forcing us to waste? Personal heaters are a summer survival tool for many office workers chilled to the bone by hyperactive ventilation systems — an act of self-defense against an epidemic of overcooling that is wasting energy and confounding comfort in not only offices but also large shops, schools and other buildings. An audit ...

  • Evaluation of the effects of varying the water velocity at the entrance of the contact zone on the performance of a dissolved air flotation (DAF) unit using the image analysis method

    For a more efficient design of dissolved air flotation (DAF) units, it is important to deepen our knowledge of the role that each constituent part plays with regard to overall performance. The velocity control of the flocculated water at the entrance (Ve) of the contact zone of DAF units is important because the degree of agitation in this region may affect the size of the flocs and the ...
