1. A gas burner, comprising: a front wall defining a front side of the burner and forming an exchanger opening for the passage of a first heat exchanger,a rear wall defining a rear side of the burner and forming a discharge opening for discharging combustion fumes,a tubular side wall extending betwe
1. A gas burner, comprising: a front wall defining a front side of the burner and forming an exchanger opening for the passage of a first heat exchanger,a rear wall defining a rear side of the burner and forming a discharge opening for discharging combustion fumes,a tubular side wall extending between the front wall and the rear wall,a tubular diffuser wall arranged within the side wall and extending between the front wall and the rear wall, said diffuser wall having a perforation for the passage of a gas mixture from an outer side of the diffuser wall to an inner side of the diffuser wall, where the combustion occurs,an annular distribution chamber formed between the side wall and the diffuser wall for the distribution of the gas mixture on the outer side of the diffuser wall,a combustion chamber formed within the tubular diffuser wall, said combustion chamber being defined on the rear side by the rear wall and suitable for the insertion of the first heat exchanger from the front side through the exchanger opening of the front wall,a cooling interspace formed within the rear wall and in flow communication with a gas inlet opening and with the distribution chamber so that a flow of the gas mixture is able to cool the rear wall, wherein the diffuser wall is internally lined with a mesh or fabric layer forming an inner combustion surface of the diffuser wall,wherein a surface of the rear wall facing the combustion chamber and defining the discharge opening is at least partially lined with a thermal-resistant mesh or fabric. 2. The gas burner according to claim 1, wherein the rear wall comprises an outer layer having a peripheral edge connected with a rear edge of the side wall, and an inner layer arranged between the outer layer and the combustion chamber and having a peripheral edge connected with a rear edge of the diffuser wall, wherein the cooling interspace is formed between the outer and inner layers, and it forms, together with the annular distribution chamber, a cup-shaped distribution cavity. 3. The gas burner according to claim 1, wherein the gas inlet opening opens into the cooling interspace externally to the annular distribution chamber, so that the gas flow enters first in the cooling interspace and then in the annular distribution chamber. 4. The gas burner according to claim 2, wherein the gas inlet opening is formed in the side wall in a zone between the outer layer and the inner layer of the rear wall. 5. The gas burner according to claim 2, wherein the outer layer and the inner layer are formed in a metal sheet in the shape of a circular disc with the peripheral edge bent in the direction of the rear side so as to define a seat for a mutual insertion with the respective rear edges of the side and the diffuser walls. 6. The gas burner according to claim 1, wherein the inner layer of the rear wall implements a second diffuser wall and has a perforation for the passage of the gas mixture from the cooling interspace to an inner side of the inner layer, where the combustion occurs. 7. The gas burner according to claim 2, wherein the inner layer of the rear wall is internally lined by a mesh or fabric layer forming an inner surface of the second diffusion wall. 8. The gas burner according to claim 1, comprising a tubular shaped first distribution wall in perforated sheet, arranged in the annular distribution chamber between the tubular diffuser wall and the side wall. 9. The gas burner according to claim 8, comprising a second distribution wall in perforated sheet, arranged in the cooling interspace between the outer layer and the inner layer of the rear wall. 10. The gas burner according to claim 9, wherein the first and second distribution walls together form a cup-shaped distributor completely surrounding the diffusion walls. 11. A thermo-dynamic fluid heating unit in an external combustion engine, said heating unit comprising the burner according to claim 1, as well as said first heat exchanger having one or more fluid ducts extending through the exchanger opening in the combustion chamber. 12. The heating unit according to claim 11, comprising a second heat exchanger arranged on the rear side of the burner and having one or more fluid ducts in a thermal exchange relationship with a fume discharge duct connected to the fume discharge opening of the rear wall of the burner. 13. Use of the heating unit according to claim 11, as a heat source for an external combustion engine, particularly for a Stirling engine.
