Fig. 19. Diagrammatic Chart Showing Distribution of Heat Available in the Fuel Under Ideal Conditions The results here represented could be obtained only under ideal operatingconditions in which no leaks existed and in which the most careful attention wasgiven to firing. The illustration represents a warm-air furnace; similar relationshold in the case of steam and hot-water units. The diagram is based on theconvention that each line radiating from the fuel bed represents 2% per cent of thetotal available heat which could be obtained by completely burning all the coalcontained in the fire pot. 46 ILLINOIS ENGINEERING EXPERIMENT STATION heat usefully, employed is smaller even than in the previous there are excessive radiation and chimney losses, such as toomuch heat in the basement or a very hot smoke pipe, the causes shouldbe investigated and corrections made in so far as possible. Figure 19 illustrates practically ideal conditions in which all ofthe losses are low and the am
