9142. Parker, S. J. April 27. Steam - generator furnaces.-Relates to a form of firetube boiler which has two fire-boxes, one above the other, each having double walls forming water - chambers. Combustion takes place simultaneously in the fire-boxes D<7> and H. The main products of combustion pass over the tubes F, perforated at F<1>, which project through the furnace front and admit air. Secondary combustion takes place as the gases pass downwards, and is assisted by the combustion products from the lower furnace, which pass over the water-walls H<1>. The mixed gases pass into the chamber 9 and the space 3 and then through the tubes E. Perforated tubes, similar to those shown at F, may be placed on each side of the walls H<1>.
