Abstract

The double-rotational-flow low-nitrogen combustor comprises a first shell, an airflow conveying assembly is arranged in the first shell and divides a cavity in the first shell into a combustion-supporting chamber and a combustion chamber, the combustion-supporting chamber communicates with a first combustion-supporting air inlet, and the combustion chamber is provided with a combustion opening; the airflow conveying assembly comprises a combustion-supporting gas rotational flow component and a fuel injection head, the combustion-supporting gas rotational flow component is provided with a first-stage rotational flow area and a second-stage rotational flow area which are both annular, and the fuel injection head is arranged in the middle of the first-stage rotational flow area and arranged on one side of the combustion cavity in a protruding mode. The first-stage rotational flow area is provided with a plurality of first-stage rotational flow channels which are annularly arranged at intervals; and the second-stage rotational flow area is provided with a plurality of second-stage rotational flow channels which are annularly arranged at intervals. Part of ammonia gas of ammonia fuel can be subjected to cracking reaction under the high-temperature oxygen-deficient condition to form hydrogen and ammonia gas to be combusted, so that the generation amount of fuel type nitric oxide is greatly reduced, and low-nitrogen combustion is realized.

Description

technical field [0001] The invention relates to the technical field of combustion equipment, in particular to a double-swirling low-nitrogen burner. Background technique [0002] At present, "hydrogen" energy is considered to be an important direction for the development of the global energy structure in the future. As a high-efficiency zero-carbon carrier for hydrogen, ammonia has a mass hydrogen content rate of up to 17.6%. It can be liquefied at 8 atm at room temperature. The industrial chain of preparation, storage and transportation Mature, and the energy density of liquid ammonia is 18.8MJ / kg, which is the most potential zero-carbon fuel to replace traditional fossil energy in power boilers, industrial furnaces, internal combustion engines, gas turbines and other industrial thermal equipment. Ammonia has the advantage of being carbon-free. The emissions after complete combustion are only water and nitrogen. As a carbon-free fuel, ammonia has the advantages of high calo...
