A Guide To Energy Efficient Paper Machine Air Systems, 2006 TAPPI Papermaker’s Conference
In the energy-intensive process of drying paper, air plays a major role as both the medium for absorbing water vapor evaporated from the sheet and also the vehicle to transport water vapor out of the process. To ensure optimum machine drying efficiency and minimal energy usage this air volume must not only be minimized but also effectively introduced into the drying environment. Heat recovery should also be maximized to further diminish expensive energy inputs.
