Problems solved by technology

[0002] At present, the burners in the combustors of hydrogen-rich gas turbines are generally swirling burners, with a flame-stabilizing hole in the head of the burner, and the combustion form is partly premixed combustion. ℃, it is easy to cause burning damage, which greatly shortens the service life of the burner; in addition, frequent replacement of the burner not only increases the maintenance cost of the gas turbine, but also causes unconventional shutdown, further increasing the operation and maintenance cost

Embodiment Construction

[0018] The present invention will be described in detail below using the drawings.

[0019] A kind of burner of hydrogen-rich gas turbine is installed on barrel-shaped combustor 10, with reference to figure 1 , The top of the barrel-shaped combustion chamber 10 is equipped with 8 burners, and air and fuel enter the combustion chamber 10 through the burners, and are fully burned inside the combustion chamber 10 to generate high-temperature working fluid.

[0020] Referring to Fig. 2, a hydrogen-rich gas turbine burner includes a liquid fuel channel 6 in the middle, a gas channel 5 is formed between the liquid fuel channel 6 and the burner inner wall 7 provided on the outside, and the burner inner wall 7 and the burner inner wall 7 provided on the outside thereof An air channel 4 is formed between the outer walls 8 of the burner, and an air channel guide vane swirler 2 is installed in the air channel 4, and a gas channel guide vane swirler 3 is installed in the gas channel 5, an...

Abstract

A hydrogen-rich gas turbine burning nozzle comprises a liquid fuel passageway on the middle portion. A gas passageway is formed between the liquid fuel passageway and a burning nozzle inner wall arranged outside the liquid fuel passageway. An air passageway is formed between the burning nozzle inner wall and a burning nozzle outer wall arranged outside the burning nozzle inner wall. An air passageway diversion piece type cyclone is installed in the air passageway. A gas passageway diversion piece cyclone is installed in the gas passageway. Flame stabilization holes are formed in the portion, below the air passageway diversion piece type cyclone and the gas passageway diversion piece cyclone, on the burning nozzle inner wall. In the air passageway, flame shielding rings are connected to the portions, close to the upper portions of the flame stabilization holes, on the burning nozzle inner wall. By means of the flame shielding rings, the combustion characteristic can be improved, gas turbine humming is reduced, the temperature of the portions close to the flame stabilization holes and the temperature of the burning nozzle inner wall are substantially lowered, safety is substantially improved, the service life of the burning nozzle is prolonged, and the operating cost of power plants is saved.

Description

technical field [0001] The invention relates to the technical field of hydrogen-rich gas turbines, in particular to a hydrogen-rich gas turbine burner. Background technique [0002] At present, the burners in the combustors of hydrogen-rich gas turbines are generally swirling burners, with a flame-stabilizing hole in the head of the burner, and the combustion form is partly premixed combustion. ℃, it is easy to cause burning damage, which greatly shortens the service life of the burner; in addition, frequent replacement of the burner not only increases the maintenance cost of the gas turbine, but also causes unconventional shutdown, which further increases the operation and maintenance cost. Therefore, there is an urgent need to develop a burner with long-term safe and reliable operation. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a hydrogen-rich gas turbine ...
