Boiler comprising a support structure, a burner mounted on said support structure, susceptible to burn a mixture of comburent air and fuel for generating a flow of hot fumes and means for transferring heat from the above-mentioned fumes to a hydraulic circuit of a carrier fluid, water in particular. Such heat transferring means are provided with at least a first heat exchanger and at least a second heat exchanger susceptible to exchange heat with the hot fumes in sequence. The boiler comprises at least one pipe made of ceramic material arranged inside the burner, susceptible to convey the fumes between the first exchanger and the second exchanger, and a plurality of nozzles for introducing the mixture. The nozzles are arranged spaced from each other inside the burner, around the above-mentioned pipe and are susceptible to generate a flame in contact with the outer surface of the pipe. |
