INVESTIGATION OF FINNED REAR WALL TUBE ARRANGEMENT FOR BOILER FURNACE,

Abstract

Rear wall refractory behind nontangent tubes cannot be expected to hold up as well as that behind tangent tube side walls. Because of a relatively short life period (about five years of service) and because of the difficulty involved in replacing rear wall refractory, fins were in stalled on the rear wall of a DLG-6 Class test boiler to determine their effectiveness in reducing rear wall refractory temperatures. As a result of finning the rear wall tubes, the average surface temperature of the rear wall refractory was reduced by 630 F, and the heat transfer or circulation of the boiler was not adversely affected. Because of the method of installation used, fin life was relatively short; and the test was terminated before it could be established whether refractory deterioration was retarded or completely eliminated.
