Wyman-Gordon in San Leandro, CA, knew the writing was on the wall. Derek Shelton, Plant Engineer, called Pacific Kiln and began the process of replacing the "Old Boy". What they ended up with was more than they expected for a lot less than they planned. It wasn't enough that they purchased a state-of-the-art "New Generation" Pusher Burnout Furnace that was more efficient, gave them more flexibility with higher temperature (2250˚F continuous) capability, and substantially cleaner, faster burnout, but the Gas Company stepped into the middle of the game and offered to pay for a chunk of the purchase, if, they also included in the purchase a "Thermal Recuperator" to preheat combustion air. How could they refuse? "The Gas Company wants to pay us to save money".
