ABSTRACT:
A friction furnace having a casing and containing a plurality of orifice plates disposed therein. The orifice plates are of two types arranged in alternating order throughout the casing; each type of orifice plate, however, having an annular ring disposed radially inward from its periphery which contains a plurality of radially disposed passages. The first type of orifice plate contains a plurality of transverse passages disposed between its periphery and annular ring whereas the second type of orifice plate contains a plurality of transverse passages disposed entirely within the diameter of its annular ring. An adjusting means is provided for varying the number of orifice plates contained within the casing. Fluid is circulated throughout the friction furnace through and around the orifice plates by a pump; and, a heat exchanger is provided in fluid communication with the furnace to transfer the heat of the circulating fluid to a directionally controlled flow of air.
