Abstract

PURPOSE:To conduct proper combustion, for instance, to maintain oxygen concentration in exhaust gas in an intended value and so forth by a method whrein the atmospheric pressure in a furnace is regulated according to fuel discharge or the air discharge for combustion based on this fuel discharge. CONSTITUTION:A heating furnace body 1 where ingots or steel pieces are processed provides a preheating zone a, a heating zone b and a soaking zone c and fuel and combustion air are supplied from pipings 2 and 7 respectively. Here, the temperature in the furnace is measured by a thermocouple 12 and the output S1, is compared with the preset temperature by a regulator 8. The deviation signal thereof S2 is input to a fuel flow rate regulator 9 and an air ratio presetter 11. The regulator 9 controls a fuel flow rate regulating valve 14 on the basis of an output S3 from a flow rate meter 13 and its deviation S4. Further, the said output S3 and the pressure S8 measured when processed substance is taken out of the furnace are input to a furnace pressure regulator 4 to obtain the deviation S9 and the signal controls the regulating damper 6 for the pressure in the furnace.
