This demand has been brought about by the educational work of civic societies, which have taught the public to realize the destructive effect and the menace to health of soft coal smoke in our large cities, and, as a consequence, the public has come to understand the large monetary loss due to the escape of unbumed gases in the form of dense black smoke. These facts are now so well understood that confirmative argument is unnecessary. The United States Radiator Corporation has developed a line of cast-iron boilers built upon the highly effective "wing-wall" principal which is well-known in power boilers where smokeless combustion is desired. Capitol Smokeless Boilers contain a large fire box or furnace where bituminous coal is burned at a rapid rate of combustion. The air is admitted through the grates and fuel bed, with an auxiliary supply admitted at the front of the furnace, which mixes with the volatile gases distilled from the fuel bed. These volatile gases pass from the furnace into a mixing chamber through two horizontal openings in the back or bridge wall of the furnace. This mixing chamber back of the furnace is formed by the bridge wall at the front and ignition walls or "wing-walls" of fire brick at the rear. The fire brick used in the ignition walls have a fusing temperature of 2700 deg. fahr. The temperature of the burning gases com ing in contact with these ignition walls does not reach this fusing point by several hundred degrees so that the fire brick used in thp ignition walls are practically indestructible. Because of the continuous volume of burning gases pouring from the furnace through the bridge wall and against these ignition walls they are constantly maintained at a temperature of approximately 1600 deg. or about 400 deg. above the ignition point of the gases. All the gases from the furnace must pass through this mixing chamber and while they enter the mixing chamber through two horizontal openings, their escape from the mixing chamber to the combustion chamber at the rear of the boiler is through a long vertical opening between the ignition walls, the area of which is slightly less than the area of the two horizontal openings into the mixing chamber. The effect of this 301
