STUDY OF THE POSSIBILITIES OF RECOVERY OF LOST HEAT IN THERMAL INSTALLATIONS
This study reports a feasibility study of a process for recovering heat from crude distillation gas in a coke plant by means of an indirect gas-gas exchanger with pipes and grating. Trials at a pilot plant at the Marienau coke plant did not produce all the results anticipated. The feasibility of the process was not demonstrated completely. It was possible to pass crude distillation gas through the exchanger pipes by minimising deposits from the point when the gas temperature remained constantly higher than the temperature at which coal tar condenses. It was not possible to conduct trials of a suitable duration. The amount of energy recovered was approximately 100 MJ per tonne of coke under the conditions of the trial. The slow operating speed of the coke plant reduced the effectiveness of energy recovery considerably. A more detailed technical-economic study leading to industrial development of the process is not planned.
