   3, Stainless steel fan control board, the test angle can be adjusted, size: 1,440 (l) x 940 (h) mm;

   4, Used to support the testing of the main frame bracket, corrosion-resistant steel, dimensions: 1,020 (l) x 1,000 (d) x 1,473 (h) mm;   

   5, Non-combustible plate Assembly, installed in front of the frame to simulate the eaves and cornice, extension of the flame from the burner to the specimen, dimensions: 330 (w) x 2,130 (d) x 584 (h) mm;      6,Air flow rate for the test panel: 19 ± 8 km/h (5.5M/sec), and configure the anemometer monitor;

   7, Separate ventilation pipes, can be extracted from outside the laboratory air;

   8, Honeycomb filter is installed in the air duct, installed gas inlet guide vane;

   9, Ventilation ducts equipped with slope adjustment panel for adjusting the air flow direction;

   10, Ventilation pipes attached to the Guide, can enhance speed to ensure supply test airflow from the outside interference, guide plates made of stainless steel, location does not change with the wind pressure;

   11, Duct materials for stainless steel, corrosion-resistant and heat-resistant, size: 2,130 (w) x 762 (h) x 3,000 (l) mm;   

   12, Fan 220V,50HZ, three-phase power, is equipped with a reverse system can automatically adjust wind speed, minimum flow for 300m3/min;   

   13, Infinitely variable speed inverter, 0-100% adjustable;

   14, Gas burners (for intermittent Shi Huo, flame spread and flying fire), 1.12m, 60.3mm, moving in the test side has a 12.7mm (w) *0.91m (long) slit;     

   15, Gas burner can provide a 22,000Btu/min (387kWh), and according to a, b, c three combustion levels, high-precision gas control valve controlling gas flow,

   16, Top burner thermocouple is installed 58.7mm, 888 ± can test 28 â„ƒ;

  17, Automatic ignition system, ensure the security of test performance, ignition electrode 1.8kVp mass flow controller is the minimum pressure according to different standards, control gas flow rates, Class A and B:21,000 ~ 22,000 Btu/min (369 ~ 387 kWh) for 10 minutes, Class C:18,000 ~ 19,000 Btu/min (316 ~ 334 kWh) 4 minutes;

 18, Temperature control system-Class A and B:760±28℃ (1400±50℉)-21,000 ~ 22,000 Btu/min-Class C:704±28 c (1300±50℉)-18,000 ~ 19,000 Btu/min

  19, High precision pressure gauges and pressure regulating valve controls the gas pressure;

1)-Each transfer to gas in the burners need to follow a different test and control methods;

2)-LNG: using MFM can accurately measure flow (flow control valve control);

3)-LPG: air flow rate using the inverter system: the test deck at 19 ± 8 km/h (5.5M/sec);

 20, Metallic mesh support materials, pallets can be rotated, so that full combustion of materials;
