Waste Heat Recovery

open access: yesEnergy Engineering, 2009
Investments in waste heat recovery provide a very attractive payback. This article covers cases implemented over the past four years among Shaw's 50 manufacturing plants. Heat sources tapped are air compressors, waste water, boiler stack gasses, and boiler blow down. The destination for the heat is process water heating and boiler make-up water heating.
