Burner with a burner head

Technical Field

The utility model belongs to the technical field of machinery, a combustor is related to.

Background

The known art combustion apparatus comprises: the combustion chamber comprises a combustion chamber with a heat exchanger, a burner connected to the combustion chamber for generating heat by combustion of a combustion air and combustible gas mixture inside the combustion chamber, and a supply conduit for supplying the gas mixture and air to the burner. The burner includes: a frame of impermeable material, which can be connected to the combustion chamber and supports a diffuser made of gas-permeable material, and a combustion surface (so-called burner head) formed by a portion of the diffuser and intended to face inside the combustion chamber and surrounded by the frame, so that the gas mixture delivered by the diffuser can burn in the form of a flame on the combustion surface.

In known solutions, the combustion surface and the frame are made as a single sheet of high temperature resistant metal plate perforated at the combustion surface and impermeable at the frame. This solution is disadvantageous due to the formation of fractures caused by the increased thermal gradient between the very hot and relatively cold regions.

To avoid breakage due to thermal stresses, it is known to the inventors to position a flexible porous layer on a perforated plate, for example a fabric or a metal fibre mesh, which serves as a combustion surface (moving the combustion zone away from the plate) and also as an insulating material isolating the plate from the high temperatures of the gases in the combustion chamber, at the expense of the need to provide and assemble additional and expensive components.
