In a recent application, Gasmac constructed and installed a new paint line for a steel processing plant in Slovakia to coat one side of steel sheeting with a decorative finish. The coating requires curing in an oven, and since the process uses solvent-based paint, the plant needed to incinerate fumes emanating during curing. Gasmac devised a system that uses a natural-gas-fed burner to heat the oven and incinerate the off-gas fumes. A Munters Thermo-Z heat exchanger captures exhaust heat at 1400°F to preheat ambient air to 1201°F at the inlet for combustion. Using this arrangement allowed Gasmac to specify a smaller burner than would otherwise have been required, reducing fuel consumption by 85%. The system also provides more control of the oven temperature and, most importantly, saves fuel for the steel company.
