[0040] In some embodiments, the hydrogen inlet may be connected to the hydrogen supply assembly 104. The hydrogen supply assembly 104 may be used to provide fuel hydrogen to the combustion chamber test piece 19. Specifically, the hydrogen supply assembly 104 may provide the combustion chamber test piece 19 with multiple channels of hydrogen at a certain flow rate and pressure.

[0041] Alternatively, if Figure 5 As shown, the hydrogen supply assembly 104 may include a hydrogen supply pipe 29 and three hydrogen outlet pipes 37. The inlet end of the hydrogen supply pipe 29 may be connected to a hydrogen station. Figure 7As shown, the hydrogen station can adopt a high-pressure gas long-tube trailer in parallel to supply gas, the number of which is 1 to 4. The hydrogen capacity of each long-tube trailer is about 3500 to 4500 Nm3 / h. The total gas consumption can meet 14000 Nm3 / h continuous experiments.

Before hydrogen is introduced into the combustion chamber test piece 19, fuel is introduced for ignition. After ignition, hydrogen is introduced to ensure safe combustion. Under pure hydrogen working conditions, fuel supply is cut off to enter pure hydrogen combustion mode. In the pure hydrogen ignition mode experiment, hydrogen is directly used for ignition experiment, and the hydrogen supply assembly 104 provides ignition duty hydrogen fuel, and the fuel supply assembly 105 is on standby.

In the working state, the second exhaust pipe section 42 may slide and adjust its position in the third exhaust pipe section 43 along the axial direction. Two exhaust pipe regulating valves 53 may be arranged in parallel on the second exhaust pipe section 42. Therefore, since the second exhaust pipe section 42 may slide and adjust its position in the third exhaust pipe section 43 along the axial direction, the assembly and disassembly of the combustion chamber test piece 19 may be facilitated. And the exhaust pipe regulating valve 53 may adjust the exhaust volume in the second exhaust pipe section 42.

[0047] In some embodiments, the water outlet of the cooling assembly 107 can be connected to the exhaust assembly 106 and the combustion chamber test piece 19. The water outlet of the cooling assembly 107 is connected to the exhaust assembly 106 and the combustion chamber test piece 19 respectively, and the cooling water of the cooling assembly 107 is divided into two parts, one part is to provide pressurized circulating water cooling for the combustion chamber test piece 19, and the other part is spray water, which directly sprays high-pressure water into the high-temperature combustion gas of the exhaust assembly 106, thereby greatly reducing the combustion gas temperature and reducing the heat load of the exhaust assembly 106 pipeline.

The reasons for the poor test availability are as follows: the above-mentioned pure hydrogen gas turbine combustion chamber test device has the ability to ignite multiple fuels such as hydrogen and light oil at the same time, while the relevant test software usually only evaluates the fuel oil electric ignition mode, resulting in an incomplete evaluation method. If the above factors are solved, the test availability can be further improved.

Wherein, the outlet temperature sensor and the outlet pressure sensor can be arranged at the outlet of the combustion chamber included in the combustion chamber test piece. The operation state of the fuel supply component is determined. Wherein, the operation state can be a start state or a stop state. In response to determining that the operation state of the fuel supply component is a stop state, the target hydrogen combustion heat information is generated according to the cooling air flow information, the first intake flow information, the second intake flow information and the various hydrogen flow information. The hydrogen combustion chamber combustion efficiency information is generated according to the combustion chamber inlet temperature information, the combustion chamber inlet pressure information, the combustion chamber outlet temperature information, the combustion chamber outlet pressure information and the target hydrogen combustion heat information.
