The Peck & Patterson Furnace for Coal Dust. The accompanying illustrations show the coal dust fur-nace patented by Peck & Patterson, 308 Second avenue,Pittsburg, as applied to return tubular boilers. To burncoal dust successfully the combustion chamber must be sep-arated from the boiler so that the cool surface of the latterwill not prevent the complete combustion of the gases in. ■-m^nfmitim contact with it. In this furnace the boiler is the entire length with a covering of fire clay orother suitable material. This casing extends about three-fifths of the distance around the boiler, or to the water line,and is placed about two inches from the boiler. The entirefurnace is lined with fire-brick. The casing, consisting ofsingle fire-clay rings, and joined together hermetically, is made to conform to tiie circle of the boiler, each end of therings bp/ng provided with a flange which rests in the sidewall, and is supported by arches as shown in Fig. I. The center of the furnace, or bridge wall, is one-third thelength of the boiler, and is divided into four spaces, orthroats. The expansion chamber is fitted with a deflectingplate at the end of the boiler. It will be seen that the fur-nace consists of three compartments, viz.; the combustionchamber, throats or bridge, and expansion chamber. This furnace is devised for the use
