    Determining optimum volume of cold and hot blast air in single-row coke cupolas
    (2005) Khatemi, Belkheir; Longa, Władysław
    In this study a formuła was derived to calculate optimum volume of cupola blast air [m /(m -s). standard operating conditions], cold or hot, for single-row coke cupolas, assuming that the lower boun-dary of the melting zone is adhacent to the upper boundary of the combustion zone (the condition of optimum cupola running formulated by A. Achenbach in 1931). Relevant eąuations and tables have also been developed to make the calculations easier. From computations madę in this study it follows that the optimum blast air volume is increasing with an increase of the blast air temperaturę, assuming for cold blast a value close to 100 m /(m -min) (Buzek postulate), with modulus of the metallic charge lumps changing in a rangę of 15 to 20 mm.
