Zusammenfassung:The present invention provides a method for controlling the combustion of a regenerative heating furnace. The method for controlling the combustion of a regenerative heating furnace, according to the present invention, comprises: a first step of detecting an in-furnace temperature by using a temperature detection sensor in the heating furnace; a second step of receiving a measured value of the in-furnace temperature, comparing the measured value with a set reference temperature value and outputting an analog signal to a sequence controller according to a value of the comparison; a third step of adjusting combustion, an amount of fuel, an amount of air and a discharge amount of combustion gas of each burner by the sequence controller by means of a program set according to the value outputted in the second step; a fourth step of measuring a pressure in the heating furnace due to the combustion gas according to a combustion load; a fifth step of comparing the measured pressure value with a reference pressure and
