DX8332B Roadway Propane Combustion Performance Testing Machine

DX8332B roadway propane combustion performance testing machine

Scope of application:

It is mainly used for the propane combustion performance test of the roadway of the whole core flame retardant conveyor belt of coal mine fabrics. According to MT914-2008 "Fabric Whole Core Flame Retardant Conveyor Belt for Coal Mine", the propane combustion performance of roadway was tested. The powerful exhaust system is adopted, and the exhaust fan system is started to discharge the exhaust gas through the water curtain activated carbon purification treatment to meet the national emission standards.

Main technical parameters:

1 aisle: consists of a chamber, the outer wall of which is constructed of 25mm refractory material, its inlet size is 460mmx460mm, length: 1676mm, and is connected to an exhaust pipe with a diameter of 300mm by a stainless steel tapered connector with a thickness of 1.5mm.

2. Exhaust hood: composed of 1.5mm thick stainless steel, placed directly above the test chamber, used to extract the flue gas diffused from outside the furnace mouth during the test process;

3. Bracket: used to place the fixed conveyor belt sample, the test bench specifications: length 1500mm, width 220mm, height 160mm, composed of steel rods with a diameter of 10mm.

4. Phenane burner: consists of six combustion injectors with the injection head inclined inward at an angle of 45°

5. Trial fuel: ≥ 95% filled propane gas (provided by the user);

6. Sample: flame retardant conveyor belt

7. Weighing device: used to weigh the weight of conveyor belt samples and gas cylinders before and after the test; 30kg/0.001kg

8. anemometer: placed on the center line at 310mm from the chamber ground and 285mm from the chamber entrance;

9. Thermocouple: K type, outer diameter is not more than 3mm; The wire diameter is 0.5 mm, the accuracy is not less than Class II., and the measuring range is 1300°C;

10. Temperature control system: computer control, the millivolt signal generated by the thermocouple is sent to the signal adjustment board, and the analog is converted into a digital signal through the data acquisition card, and then controlled and reported by the computer software;

11. Timer: Resolution: 0.1S, error is not more than 1s/h

12. Fuel flow meter: 35~350L/H adjustable control accuracy±2L/h

13. Fuel consumption control accuracy: 565±2g/50min

14. Power supply voltage: AC380V 50Hz three-phase five-wire system;

15. power consumption: 4.01KW;

16. Test environment temperature: 5°C--30°C

17. Vertical turning 6800*4400*2700mm or horizontal straight line 9500*1800*2700mm

Equipment composition:

It is composed of four parts: the main control box, the blower device, the combustion bracket, and the burning blowtorch.

The control box is removable.

Air purification of the exhaust fan: After the exhaust duct is installed in the exhaust duct, the air passes through the roadway, and the flow rate of the air is controlled by the control valve.

The frame material is made of high-quality 304 stainless steel square welding, and the control box is made of (t=1.2mm) electrostatic steel plate, and the surface is sprayed with plastic, which is more smooth and beautiful.

Blowtorch: SUS304 material, my company self-made.

Control system:

6.1 The control box adopts relay control system, and all electronic components are made of domestic leading brands, which can better ensure the working performance and detection accuracy of the machine.

6.2 The temperature adopts imported intelligent P.I.D. thermostat (with the function of automatic calculation) and high-precision PT100 thermocouple sensor and timer.

6.3 The equipment has the following safety protection devices: power overload protection, short circuit protection, control loop overload protection, ultra-high temperature protection.
