Abstract:
A specially designed integrated renewable energy system is operative to more efficiently and less expensively provide heating energy for conditioned space supply air and domestic hot water heating in a residential application of the type which heretofore might utilize a fuel-fired or electric furnace and a fuel-fired or electric storage type water heater to respectively generate space heating air and domestic hot water. The system utilizes solar energy in combination with what, at least predominately, are conventional, off-the-shelf air and water heating components to substantially reduce air and water heating costs in a simple manner.
Abstract:
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. Via a flame carryover structure, a single igniter is utilized to ignite all of the burners.
Abstract:
An air sanitation device is disclosed. The air sanitation device can include a base section, a body section, and an air movement device configured to move air through at least a portion of the air sanitation device. The air sanitation device can move air from an inlet of the air sanitation device, and past an ultraviolet (UV) light source, and out an outlet of the air sanitation device. The air sanitation device can be configured to draw in air from within or below a breathing zone. The air sanitation device can be configured to draw in air from below the breathing zone and output sanitized air. The sanitized air can be outputted at an angle such that the sanitized air flows in a generally downward direction.
Abstract:
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.
