The purpose of the present invention is to provide an apparatus for producing inorganic spheroidized particles, which is capable of greatly reducing the amount of greenhouse gases generated and suppressing coal ash generated during combustion. Provided is an apparatus (10) for producing inorganic spheroidized particles, comprising: a burner (11) for producing inorganic spheroidized particles; a vertical spheroidizing furnace (15); an ammonia supply source (12); an oxygen supply source (13); an ammonia supply line (L1) located between the ammonia supply source (12) and the burner (11) for producing inorganic spheroidized particles; and an oxygen supply line (L2) positioned between the oxygen supply source (13) and the burner (11) for producing inorganic spheroidized particles.
Description
technical field [0001] The present invention relates to an apparatus for producing spheroidized inorganic particles and a method for producing spheroidized inorganic particles. Background technique [0002] Conventionally, methods for producing inorganic spheroidized particles (hereinafter, sometimes simply referred to as "spheroidized particles") by passing an inorganic powder raw material through a flame are known (Patent Documents 1 to 3). [0003] For example, in the inorganic spheroidized particle manufacturing apparatus disclosed in Patent Document 2, as Figure 10 As shown, the raw material powder is supplied from the raw material supply device (feeder) A, and is conveyed to the burner B together with the carrier gas supplied from the carrier gas supply device A'. Oxygen from the oxygen supply facility C and fuel gas (liquefied petroleum gas: LPG) from the LPG supply facility D are supplied to the burner B. Then, the exhaust gas including the particles spheroidized i...
