摘要:
A combustion facility (1) using heat accumulation type burners, including: a furnace body (2): and a pair of burners (11A, 11B) provided in the furnace body and each including a heat accumulator (12A, 12B), wherein while the pair of burners are caused to alternately combust in the furnace, a combustion exhaust gas in the furnace is taken in by a burner in a state of non-combustion to accumulate heat in a heat accumulator of the burner, and a predetermined amount of combustion gas is supplied to a burner in a state of combustion (11A), so as to cool a heat accumulator (12B) of the burner and also preheats the combustion gas by heat released from the heat accumulator, the combustion facility further comprising a gas supply unit (31) that supplies a predetermined amount of combustion gas, and also a non-combustion gas which does not produce a disturbance in combustion, to the burner in the state of combustion, so as to cool the heat accumulator of the burner.
