Abstract
A gas-fired burner wherein a back plate having at least one inlet tube is connected with respect to a flameholder plate having a plurality of ports. The flameholder plate and the back plate form a plenum. A plurality of mixing baffles are formed within the plenum and between the back plate and the flameholder plate. A radiation plate is also connected with respect to the flameholder plate, the radiation plate and flameholder plate forming a combustion chamber with at least one gas flow boundary serving as a heat radiating surface.
Claims26
A gas-fired burner comprising:
- a back plate, the back plate having at least one inlet tube;
- a flameholder plate having a gas impervious region and forming a plurality of ports peripherally disposed around at least a portion of said gas impervious region, the flameholder plate positioned on the back plate and forming a plenum between the back plate and the flameholder plate;
- a radiation plate connected with respect to the flameholder plate, the radiation plate and the flameholder plate forming a combustion chamber there between configured substantially coincident with said plurality of ports wherein at least one gas flow boundary also serves as a heat radiating surface;
- and
- an outlet formed in the combustion chamber.
A radiant burner comprising:
- an inlet;
- a flameholder plate having a gas impervious center region and forming a plurality of flame ports around at least a portion of the gas impervious center region, forming a plenum with the inlet;
- a radiation plate connected with respect to the flameholder plate, the radiation plate and the flameholder plate forming a combustion chamber having a configuration corresponding to a flame port configuration of said plurality of flame ports, wherein at least one gas flow boundary also serves as a heat radiating surface;
- and
- an outlet formed in the combustion chamber.
A method for heating comprising the steps of:
- introducing fuel and oxidant into an inlet;
- directing the fuel and oxidant through a plurality of baffles to form a premixture;
- directing the premixture through a plurality of ports disposed between said plurality of baffles and a periphery of a flameholder plate;
- igniting the premixture to form a flame;
- directing hot combustion gases generated by the flame against a radiation plate and across a combustion chamber formed between the radiation plate and the flameholder plate and configured to correspond to said disposition of said plurality of ports;
- and
- conveying the hot combustion gases into an outlet formed in the combustion chamber.
