The present invention aims to generate steam by using energy that occurs at the time of generating an inert gas. A boiler (3) includes: a furnace (16); a steam generation unit (17); an upper burner (18) that is provided in the upper portion in the furnace (16) and combusts fuel; and a lower burner (20) that is provided in the lower portion in the furnace (16), combusts the fuel, and generates an inert gas having an oxygen content of 1% or less, at which no reaction occurs with a flammable gas. A side water-cooling wall (32) and a bottom water-cooling wall (33) are provided along the furnace bottom of the furnace (16) and the side wall of the lower portion of the furnace (16), and a bottom refractory (35) and a side refractory (36) are respectively provided between the side water-cooling wall (32) and a flame formed by the lower burner (20) and between the bottom water-cooling wall (33) and the flame.
