1. Design and technological recommendations have been made for improving flame calcination of the S-8B electrolyzer and the KrAZ calcination system employed:- nonuniform positioning of the burner units along the sides of the bottom;- an optimum calcination time of no less than 72 h (not just for the S-8B electrolyzer but also for other electrolyzer types);- regulation of fuel delivery rate by increasing it in steps over time;- assurance of a reducing flame in burning the fuel;- shielding the cathode surface with metal covers before calcination;2. A generalized equation has been proposed for calculating the mean bottom temperature at any time during flame calcination as a function of the amount of heat consumed.3. It has been established that only about 25 percent of the heat liberated in flame calcination goes to heat the bottom, with the remainder being expended in heating other electrolyzer structural elements and lost to the environment.4. Increasing calcination fuel efficiency requires that the temperature of the combustion products leaving the electrolyzer be lowered by passing them over the bottom peripheral seams before they are removed through the exhaust system.5. It has been established that the amount of heat accumulated by the bottom decreases with time. Prolongation of calcination beyond the optimum time consequently leads to unwarranted fuel consumption.
