ABSTRACT:
A flame arrester having a rectangular housing of internal width W, length L and heighth H filled with a plurality of contiguous convoluted planar laminae. Each lamina is comprised of a thin sheet of metal formed with a plurality of spaced parallel shallow channels of selected depth D. As the laminae are placed in the housing in parallel contiguous contact to fill the cross-section of the housing, there will be a great plurality of narrow slots of width D through which the gas will pass to the flame area. Means may be provided in the form of shallow protrusions of heighth D pressed into the metal in the flat areas of the sheet in order to insure that the spacing between sheets at all points is close to the value D.
