PATENT STEAM-BOILER FURNACE, with patent air-diffusing and smoke-consuming fire bars.
In this furnace, of which the figure is a transverse section, the walls and bridge, instead of being of fire-brick, are formed as water spaces, through which the feed water is introduced, and is compelled to traverse their entire length before entering the boiler. This, in conjunction with the patent bars shown, effects a great saving of fuel. The same principle is applicable also to various other purposes.
