The final air toxic rules for institutional, commercial, and industrial (ICI) boilers (after almost two decades of legal wrangling, political pandering and intrusion, and boiler-user dread) have been inked and will soon be published in the Federal Register - an action that will begin the compliance clock ticking for new and existing boilers in these sectors.
For almost a century, operators of boilers and steam using equipment have realized the benefits of higher process efficiency and extended equipment life made possible by reducing the feedwater dissolved oxygen (DO) levels to the lowest possible values.
Terminal devices, pressurization, supply air, proper exhaust … those factors and more go into a well designed VAV system for sensitive lab applications. From general tips to changing details such as fabric duct elements, booster fans, and a new AMCA standard, the author equips you to succeed in one space that is no place for experimentation.
Most of us think of data centers when we think “mission critical,” but
the category goes into financial and health sectors as well. These
five phases of commissioning can provide some additional peace of
mind about performance, no matter which type of critical mission is
at stake.
