In upstate New York Globe Metallurgical produces chemical- grade silicon metal and silicon-based specialty alloys for solar cells. Silicon furnaces burn very hot, as high as 6,000° F, and often give off thick, dirty smoke. Globe called in Moffitt to solve these problems to help improve the internal air quality, and ensure that their emissions met EPA standards.
Moffitt installed a large Labyrinth natural ventilator onto the this very high (around 100 feet), very steep (a pitch of 3.5/12) roof. This natural ventilation device enables the hot, dirty air to escape from the facility, making the interior cooler and more comfortable.
Dampers were added to the Labyrinth unit to allow for the controlled capture of the smoke. They ensure that the dirtiest smoke, that is produced when the furnace is first lit, can be captured and redirected. As the furnace begins to burn clean, the dampers are opened to increase the rate of heat evacuation.
The Labyrinth allows the building to meet EPA regulations and makes the facility cooler, brighter and smoke free. This creates a much more comfortable, and safer situation for the workers.
