HEAT EXCHANGER--Designed and constructed in a near tear-drop shape which permits the air to flow with a mini mum of friction. This design affords a maximum of both strength and area in its crown sheet, and reduces power consump tion to the very minimum. COMBUSTION CHAMBER--Fabri cated from four way *1, and \i in- floor plate. The chamber is of the correct size and shape to provide proper volumetric content for the complete combustion of oil or gas. Fired "with Gas or Oil BLOWERS--Three standard up-blast discharge, multi-vane Blowers, each in dividually powered, are provided to supply the correct amount of air to properly cool the Heat Exchanger. Individually-drivfen Blowers are used because of the great flexi bility of operation obtainable. Uniform bonnet temperature may be enjoyed by the simple expediency of increasing or , reducing the amount of air driven around any particular section of the Heat Ex changer.
