A burner with internal fumes recirculation comprising: - a first supply duct, for supplying fuel, having at least a first inlet opening and a first outlet opening; - a second supply duct, for supplying comburent, having at least a second inlet opening and a second outlet opening; said first outlet opening and second outlet opening being confluent at a head of the burner configured to generate a flame; - suction means configured to suck at least an amount of comburent from an environment outside said burner and to move said at least an amount of comburent from said second inlet opening to said second outlet opening; - a fumes return duct for fumes generated by the combustion of said flame and configured to promote a re-introduction of the fumes in said burner; wherein said fumes return duct has a third fumes inlet opening arranged at said head of the burner; wherein said fumes return duct has a third outlet opening placed in fluid communication with said second inlet opening for the comburent to promote an at least partial re-introduction of the combustion fumes in said second comburent supply duct; and wherein said suction means is configured to promote a movement of the combustion fumes from said fumes return duct to said second supply duct; - a heat exchange section interposed between said third inlet opening and said third outlet opening and configured to promote a decrease in the temperature of the combustion fumes during a passage thereof between said third inlet opening and said third outlet opening; wherein said heat exchange section is obtained by means of a heat exchanger interposed between the third inlet opening and the third outlet opening of said fumes return duct; characterised in that said heat exchanger comprises a tube bundle obtained as a branch of said second supply duct and a shell container obtained as an enlargement of said fumes return duct. - a first supply duct, for supplying fuel, having at least a first inlet opening and a first outlet opening; - a second supply duct, for supplying comburent, having at least a second inlet opening and a second outlet opening; said first outlet opening and second outlet opening being confluent at a head of the burner configured to generate a flame; - suction means configured to suck at least an amount of comburent from an environment outside said burner and to move said at least an amount of comburent from said second inlet opening to said second outlet opening; - a fumes return duct for fumes generated by the combustion of said flame and configured to promote a re-introduction of the fumes in said burner; wherein said fumes return duct has a third fumes inlet opening arranged at said head of the burner; wherein said fumes return duct has a third outlet opening placed in fluid communication with said second inlet opening for the comburent to promote an at least partial re-introduction of the combustion fumes in said second comburent supply duct; and wherein said suction means is configured to promote a movement of the combustion fumes from said fumes return duct to said second supply duct; - a heat exchange section interposed between said third inlet opening and said third outlet opening and configured to promote a decrease in the temperature of the combustion fumes during a passage thereof between said third inlet opening and said third outlet opening; wherein said heat exchange section is obtained by means of a heat exchanger interposed between the third inlet opening and the third outlet opening of said fumes return duct;
