Abstract
It is described a combustion head consisting of a plurality of balls (10) of ceramic material joined to each other at points of mutual tangency to substantially form a filter bed. On passing through the ceramic head, the combustible gas-combustion air mixture is shared out among a multiplicity of hollow spaces (11) following each other to form a tortuous path, in order to ensure an optimal mixing. At the combustion head exit the gas-air mixture fires forming a flame front extending over the whole external surface (1a) of the combustion head.
Claims25
A gas burner comprising:
- an internally hollow mixing body (2),
- means (3) for feeding a combustible gas-combustion air mixture into the mixing body (2),
- a combustion head (1) provided with delivery ports (12) through which the combustible gas-combustion air mixture is ejected from the mixing body (2) and fired, said combustion head comprising:
- a box-shaped holding body (13) received in a perimetric seat (2b) defined by an upper edge (2a) of said mixing body (2), said box-shaped body having at least one bottom (14) provided with a plurality of through apertures (14a) and at least one side wall (15) extending perimetrically from said bottom (14) with which it defines a housing (16) a plurality of granular elements (10) received in said housing (16) defined in the box-shaped body, said granular elements being physically interconnected with each other in succession at points of mutual tangency, to substantially define a filter bed having a lattice of hollow spaces (11) intercommunicating with each other and defining on an external surface (9) of the combustion head (1), a plurality of said delivery ports (12) distributed over the whole extension of the external surface itself.
A method of manufacturing and setting up a gas burner comprising an internally hollow mixing body (2), means (3) for feeding a combustible gas-combustion air mixture into the mixing body (2), and a combustion head (1) provided with delivery ports (12) through which the combustible gas-combustion air mixture is ejected from the mixing body (2) and fired, said method comprising the following steps:
- manufacturing a box-shaped holding body (13) having at least one bottom wall (14) provided with a plurality of through apertures (14a) defining a substantially netlike structure, and at least one side wall (15) extending perimetrically from said bottom wall (14) and defining a housing (16) therewith;
- pouring a plurality of granular elements (10) into said housing (16) so as to substantially make a filter bed formed with a lattice of hollow spaces (11) intercommunicating with each other and defining a plurality of said delivery ports (12);
- associating with said granular elements (10), on top of the same, a closing element (17) provided with a plurality of through apertures (17a) defining a substantially reticular structure;
- wherein after said manufacturing step another step is provided in which the box-shaped holding body (13) is engaged in a perimetric seat (2b) defined by an upper edge (2a) of said mixing body (2).
