Gehb,

Detailed calculations and heat-flow diagrams are given for two possible arrangements of the heat-dissipation system. One arrangement would have used some waste heat to generate steam, whereas the other would simply have dissipated that heat in a radiative air cooler. For the case in which steam was to be generated, the following figures were given in a heat-flow diagram, with all figures representing millions of kcal/hr: heat into oven from coal paste and circulating gas, 2.39; heat into oven from heat exchanger, 3.0; heat into oven from preheater, 7.705; heat into oven from cold gas, 0.465; heat generated in oven by reaction, 6.25; heat out of oven in product, 1.51; heat out of oven into heat exchanger, 3.1; heat out of oven in residues, 3.0; radiation loss in oven and later processing, 0.5; heat out of oven used to generate steam 5.3; heat out of oven lost in water cooler, 6.4 (thus heat into oven and generated in oven = 19.81 = heat out of oven and radiation losses). These figures were calculated for a total of 4 four-oven chambers with 18-meter ovens and a 150 m/sup 3/ total reaction space and throughputs of 33.6 metric tons/hr of coal paste, 4,000 m/sup 3//hr of newly-made gas, 26,000 m/sup 3//hr of circulating gas, and 36,000 m/sup 3//hr of cold gas. The values for heat lost in making steam and the heat lost in water coolers were calculated on the basis of the necessary drops to which they corresponded. 2 diagrams
