Abstract
A catalytic burner for a hydrogen fueled boiler is provided. The catalytic burner comprises one or more of an inlet port, an outlet port, a fan, and a catalytic section. The catalytic section comprises at least one self-priming catalyst. The fan is successively disposed downstream of inlet port(s) and is configured to simultaneously draw, mix, and feed air and hydrogen to the catalytic section.
Claims19
A catalytic burner for a hydrogen boiler comprising:
- at least one inlet port for supplying air and hydrogen;
- an outlet port for discharging combustion products;
- at least one fan for supplying air;
- and
- a catalytic section comprising at least one self-priming catalyst that is configured to initiate and complete a combustion reaction of an air-hydrogen mixture;
- wherein the at least one fan is arranged in a fluid connection with the at least one inlet port (11, 11′, 11″), and arranged one of subsequently and downstream of said the at least one inlet port;
- and
- wherein the at least one fan is configured to supply air and hydrogen and to simultaneously draw, mix and inject the air and the hydrogen towards the catalytic section.
A boiler plant comprising a catalytic burner, wherein the catalytic burner comprises at least one inlet port for supplying air and hydrogen, an outlet port for discharging combustion products, at least one fan for supplying air, and a catalytic section comprising at least one self-priming catalyst that is configured to initiate and complete a combustion reaction of an air-hydrogen mixture, wherein the at least one fan is arranged in a fluid connection with the at least one inlet port and arranged one of subsequently and downstream of the at least one inlet port, and wherein the at least one fan is configured to supply air and hydrogen and to simultaneously draw, mix and inject the air and the hydrogen towards the catalytic section, the boiler plant comprising
- at least one heat exchanger arranged downstream of the catalytic burner through an outlet port and configured to exchange heat of reaction products with a consumer circuit;
- an exhaust fumes discharge line connected at the outlet of the heat exchanger ;
- at least one air inlet line connected to the at least one inlet port;
- and
- a hydrogen inlet line connected to the at least one inlet.
