<p>The objective of the present invention is to provide a combustion device, which can cool a combustion chamber without using an insulation material, preventing generation of condensed water while using a pre-mixed burner, and in which a flow path connection structure between gas and air can simplified. To this end, the present invention relates to the combustion device comprising: a blower for supplying air; a burner for combusting a mixture of the air and the gas; and a heat exchanger in which heat exchange with water inside takes place by means of combustion heat of the burner, wherein the burner comprises a center portion that is placed at the center of the burner, and a periphery portion that encases the center portion, wherein the mixture of air is combusted in the center portion of the burner, only air is exhausted from the periphery portion of the burner, and wherein a flow path connection portion is provided between the burner and the blower, the flow path connection portion comprising a first flow path connection member provided with a first air passage therein that connects to the center portion, and a second flow path connection member provided with a gas inlet portion into which gas that is supplied to a second air passage that connects to the periphery portion and the first air passage is introduced.</p> |
