The present invention provides an alternate changeover regenerative burner system suitable for use as a heat source for an industrial furnace and the like where re-increase in temperature is relatively-often carried out; an alternate changeover regenerative burner constituted by a burner,having a regenerator,and air supply/exhaust switching mechanisms,and,for switching connection with an air supply system,and an exhaust system,of the burner,is regarded as a module unit; and three or more units of the alternate changeover regenerative burner constitute a combustion system,a ratio of the number of the burners,performing combustion and the number of the burners,being stopped is variable; and combustion is controlled in such a manner that all the units sequentially repeat alternate regenerative combustion with the units forming no fixed pairs. According to the present invention, a flow velocity of air injected from a burner throat can be variable irrespective of a quantity of combustion; the flow velocity of air emitted from the burner throat can be maintained high even if the operation is carried out with a quantity of combustion lower than the burner capacity; and a non-stationary flame can be formed in a wider range.
