Abstract
A board-plank premixing burner port arrangement which increases durability by preventing a large force from being applied to a burner-fixing structure despite accumulated thermal expansion caused by red heat on a burner surface. A burner body unit includes partially cut and stacked plates. The plates form a gas mixture passage and a burner port, are disposed such that cut parts of the neighboring plates intersect one another. The board-plank premixing burner port arrangement has increased combustion efficiency by reducing burner port deformation, and is easily manufactured at a low cost through a simplified installation structure of the burner port.
Claims9
A burner port arrangement comprising:
- an inner plate having front and rear surfaces and including, between the front and rear surfaces, sequentially arranged, a plurality of sets of cut plates;
- and
- first and second outer plates respectively bonded to the front surface and the rear surface of the inner plate and sealing gas mixture passages of the burner port arrangement at the front and rear surfaces of the inner plate, wherein
- each of the sets of cut plates includes a plurality of overlapped cut plates,
- each of the cut plates within a set of cut plates is partially exposed between an adjacent pair of the cut plates,
- each of the cut plates includes
- a pair of body elements disposed at opposite ends of the respective cut plate,
- a plurality of T-shaped elements disposed between the body elements and spaced apart from each other, and
- a fastening element extending laterally between and connected to the body elements and to the T-shaped elements, coupling the body elements to the plurality of T-shaped elements, and
- adjacent cut plates are overlapped and joined to each other thereby forming, in spaces between the T-shaped elements, at least one gas mixture passage for the passage of a gas mixture and, between top surfaces of the T-shaped elements, at least one burner port for escape and burning of the gas mixture.
A burner port arrangement comprising:
- a burner body unit including a plurality of overlapping partially cut plates, wherein the burner body unit includes
- inner plates comprising sets of plates overlapped repeatedly, wherein
- each of the inner plates is partially exposed between adjacent inner plates, and
- each of the inner plates comprises
- body elements disposed on opposite ends of the inner plates,
- a plurality of T-shaped elements disposed between the body elements at an interval, and
- fastening elements located laterally between the body elements and coupling the body elements and the plurality of T-shaped elements with one another, and
- outer plates bonded to a front surface and a rear surface of the inner plates and sealing front and rear surfaces of the gas mixture passage;
- and
- a gas mixture passage and burner ports defined by alternating cut parts of adjacent plates of the partially cut plates.
