  • Patent number: 10060621
    Abstract: Provided is a gas-air mixing device for a combustor which effectively controls the amount of gas and air supplied to a burner provided in a combustor, such as a boiler or a water heater, thus improving the turn-down ratio which leads to increased convenience for using hot water and heat and enhanced durability of the burner. The gas-air mixing device for a combustor comprises: a housing, connected on one side to a turbo fan; a discharge part disposed on one side of the housing and in contact with the turbo fan; first and second air supply parts, provided on the other side of the discharge part and separated by a first partition; first and second gas supply parts, separated by a second partition; and an opening/closing means for controlling the flow of gas and air by opening or blocking the second air supply part and the second gas supply part.

  • Publication number: 20110114300
    Abstract: A heat exchanger of an upward combustion condensing boiler maximizes latent-heat recovery efficiency by causing the flow direction of exhaust gas to coincide with the flow direction of condensed water in a latent heat exchange unit. The heat exchanger includes a sensible heat exchange unit that absorbs sensible heat generated from an upward combustion burner; a latent heat exchange unit that absorbs latent heat of vapor included in exhaust gas which has been heat-exchanged in the sensible heat exchange unit; and a condensed-water tray that discharges condensed water generated from the latent heat exchange unit.
