Abstract 1. IN A METHOD OF OPERATING A COKE PLANT, FEEDING PULVERIZED COAL INTO A COAL DRYER, DIRECTING A HOT DRYING GAS AT A FIRST GIVEN TEMPERATUE UPWARDLY THROUGH THE COAL DRYER AND SUSPENDING THE PULVERIZED COAL IN THE UPWARDLY FLOWING DRYING GAS TO FORM A FLUIDIZED BED, CIRCULATING A DRYING FLUID THROUGH COAL BY CONTACT WITH THE COILS, HEATING THE DRYING THE COAL BY CONTACT WITH THE COIL, HEATING THE DRYING FLUID CIRCULATED THROUGH THE COILS AT LEAST INDIRECTLY WITH HEAT EXTRACTED FROM HOT COKE SHORTLY AFTER THE COKE IS DISCHARGED FROM A COKE OVEN, TRANSPORTING DRY COAL AT A SECOND GIVEN TEMPERATURE FROM THE COAL DRYER INTO A HEATER, EXPOSING THE DRY COAL IN THE HEATER TO A HEATING GAS AT A TEMPERATURE SUBSTANTIALLY HIGHER THAT SAID FIRST AND SECOND GIVEN TEMPERATURES AFTER PRELIMINARILY HEATING THE LATTER GAS WITH HEAT EXTRACTED FROM THE HOT COKE, AND DELIVERING THE DRY, HEATED COAL TO A COKE OVEN SO THAT THE COAL IS RECEIVED AT THE OVEN IN A DRY, PREHEATED CONDITION.
