Technical parameters

1. Laboratory: the wall adopts high temperature refractory brick, the inner surface is treated with black, and the wall dimension is W2438 x D2438 x H3353mm; painted

2. Laboratory door: W0.9 x H2m stainless steel frame, toughened glass door;

3. Smoke collecting tower: the inclination angle of 40 degrees, the cube is 914mm; the filter length is 610mm;

4. Observation window: the side length is 457mm, the distance from the bottom to the ground is 1295mm, and the right to the wall is 1143mm.

5. Air inlet: 559 x 343mm, 914 x 305mm, 2438 x 343mm;

6. Exhaust pipe: L9000 * dia 406mm, installed in the tower on the right side of the cube collection level;

7. Burning ladder: high 2400mm, L305 * W25 * D25. The 299mm distance between two square;

8. A: there are 242 hole L341mm * D30mm;

9. Gas flow: 13.2L/mim, standard pressure and temperature, mass flow control;

10. Air flow: 76.8L/mim, standard pressure and temperature, mass flow control;

11. Flow detection: the differential pressure flow meter is used to measure the flow rate of the exhaust pipe, providing the basis for controlling the speed of the fan.

12. Transmittance: the silicon photocell detects the smoke density of the sample when the sample is burned.

13. Flame height: infrared visible light in real time indicates the current flame height;

14. Special software: can draw the real time pipeline flow, smoke density, flame height and other data to draw the curve, and generate reports, can be preserved for inspection or printing;

15. Control system: computer + control software, mass flowmeter, etc.
