ABSTRACT:
A method for controlling temperature in a heating kiln is able to maintain the temperature uniformly at a set temperature of the kiln. Output of each burner provided in the kiln is controlled on the basis of temperatures at plural positions affected by plural burners to make the temperature in the kiln substantially equal to a set temperature of the kiln. Mean values of temperatures at the plural positions are calculated and the burners are controlled to bring the mean values into coincidence with the set temperature. Alternatively, contribution rates .alpha.1 and .alpha.2 are determined which correspond to the influence of one burner on the temperature of the thermocouple for the other burner. Handicap temperatures TH1 and TH2 are then calculated by substituting temperatures T1 and T2 of the one and the other burners in equations TH1=T1+(T2-T1) .alpha.1 and TH2=T2+(T1-T2) .alpha.2. The burners are then controlled to make the handicap temperatures coincide with the set temperature.
