A combustion apparatus includes a combustion chamber (6) and a single-type regenerative combustion burner (1). The burner (1) is arranged with respect to the combustion chamber (6) so that a direction in which burnt gas (8) returns to the burner is not opposed to a direction in which fuel and supply air (7) are expelled from the burner (1). This combustion apparatus is applicable to various types of industrial furnaces including various types of boilers, for example, a crucible-type furnace. <IMAGE>
