Deck slope control | Can be easily controlled by 1 cylinder |
Fire board | With test deck |
Temperature control valve | Automatic temperature control valve is used |
Grade A, B temperature & heat output | 760 ± 28 °C (1400 ± 50 °F) - 21000 ~ 22000 BTU/min (369 ~ 387 KWH) |
Grade C temperature & heat output | 704 ± 28 °C (1300 ± 50 °F) - 18000 ~ 19000 BTU/min (316 ~ 334 KWH) |
Gas delivery test & control methods | Different test and control methods are required for each gas delivered to the burner |
LNG gas flow control | Accurate measurement of gas flow with MFM (gas flow controlled by automatic control valve) |
LPG air flow adjustment | Use inverter system to adjust air flow rate: The speed on the test deck is 19 ± 8 km/h (5.5 m/sec) |
Ignition method | The automatic ignition method is adopted, and the test can be automatically ignited at the same time |
Ventilation duct protection | A guide plate is attached to the ventilation duct to protect the airflow turbulence supplied to the test deck from external interference |
Ventilation duct adjustment | A slope adjustment panel is installed on the ventilation duct to adjust the direction of air flow |
Thermocouple installation & temperature test | A thermocouple is installed at 58.7mm at the top of burner 12, and the temperature can be tested at 888 ± 28 °C |
Test control system | The DAQ system can automatically control and complete the test |
