A fuel-fired furnace incorporates specially designed fuel/air mixing and combustion structures. The fuel/air mixing structure is of a mixing sound-attenuating design and comprises a venturi having a perforated sidewall portion and being surrounded by a noise-damping housing chamber communicating with the interior of the venturi via its sidewall perforations. During use of the mixing structure, air is flowed through the venturi in a swirling pattern while fuel is transversely injected internally against the swirling air. The combustion structure comprises a burner box housing into which the fuel/air mixture is flowed, combusted, and then discharged as hot combustion gas into and through the heat exchanger tubes. The fuel/air mixture entering the burner box housing initially passes through a non-uniformly perforated diffuser plate functioning to substantially alter in a predetermined manner the relative combustion gas flow rates through the heat exchanger tubes.

Installed in a fuel-fired heating appliance is a specially designed burner assembly operative to receive and combust a pre-mixed flow of fuel and air to create therefrom a spaced apart plurality of flames which are aligned with and flow directly into the inlets of a corresponding spaced plurality of heat exchanger tubes. The flames create within the tubes hot combustion gases that transfer combustion heat to a supply fluid flowed externally across the tubes. The burners are of a hollow perforate metal construction, are mounted on and forwardly project from a support structure toward the tube inlets, and have rearwardly facing open inlet ends that receive the pre-mixed flow of fuel and air. In one illustrated embodiment thereof, the burners have conical configurations, and in another illustrated embodiment have generally dome-shaped configurations. Via a flame carryover structure, a single igniter is utilized to ignite all of the burners.
