ABSTRACT:
The device is a baffle array that is housed in a section of pipe that coupled from an oil burner to a chimney. The baffle array, when closed, blocks about 70 percent of the pipe cross-sectional area and opens upon the occurrence of a small explosion when the oil burner starts to permit this explosive puff to pass to the chimney. The baffle array includes three baffle plates, each pivoting at its top end and all interconnected at the bottom end.
