Abstract
The aim of this study is to remove crack on a ventilation device at the suction part of zinc plating factory, and the main point is making optimum configuration by improving an existing hood system. The result shows that existing hood system has problem with duct configuration, angle and reducer. Model-5 shows lowest pressure difference as meaning of suction capability. The hood inlet surface has most uniform suction capability.
