Abstract: A temperature sensor (1) for gas burner (2) having a thermocouple (11) comprising electric conductors (15) and a connection element (12) to connect to the burner (2) associated with a free end (18) of such thermocouple (11), said connection element (12) being suitable for being inserted inside a seat of the sensor (8) formed inside a wall (4) of the burner (2) and having a first end (26) suitable for being placed at the outer surface (6) of the burner (2), said thermocouple (11) being inserted inside a blind hole (29) of the connection element (12) which opens at a second end (28) of said connection element (12). Said blind hole (29) ends with at least one part (31) convergent towards an end zone (K) of the hole (29), said part (31) getting in contact with the thermocouple (11) inserted inside the connection element, the connection element (12) being made from an iron-chrome-aluminum alloy. An assembly comprising such temperature sensor and a burner is also claimed.

Abstract: A new and improved gas fired burner unit that can be utilized in applications where low emissions and high efficiency are desired including a burner body having a lower housing unit with a bottom portion, a distribution element located above the bottom portion, a burner deck located above the distribution element, and a metal fiber mesh element located above the burner deck. The burner deck supports the metal fiber mesh and spaces the metal fiber mesh from the internal distribution element to define a burner head. At least one inlet conduit communicates with the burner body and extends into the burner body to deliver a gas/air mixture to the burner body in a region located below the distribution element and above the bottom portion of the lower housing unit. The burner head has a permeability greater than 700 liters per hour, and the bottom portion of the lower housing unit includes a plurality of ribs providing added rigidity to the burner body and eliminating combustion noise.
