CONTROL OVEN AND DRYER DAMPERS: FOR ENERGY SAVINGS

摘要

By automating damper controls on ovens, as much as a 50 percent reduction in fuel costs can be realized. As the cost of fuel increases, so do the concerns about energy optimization and safety. Learn how to safely use flamma-bility monitoring to effectively automate damper controls and reduce the costs of owning and operating ovens and dryers. First, a few safety points must be noted. Automating damper controls to modulate the flow of fresh air or exhaust through an oven can reduce the amount of fresh ventilated air moving through the system. In turn, this reduction greatly reduces the consumption of natural gas used for heating any unnecessary added air (figure 1). However, when doing this, care must be taken.
