C) The barrel thickness is greater than 1/10 of the diameter of the barrel

D) The lid can accommodate the crucible and electronic ignition device, the lid and all the sealing devices can withstand the internal pressure of 21Mpa

E) The inner wall of the barrel can withstand the erosion of sample combustion products by using the USU304 stainless steel, and can resist the point corrosion and inter granular corrosion caused by the acid produced by combustion.

2. Calorimeter

External calorimetric apparatus for double container with insulation cover, filling between the internal and external wall thermal insulation material, outer tube filled with water, the outer wall around 10 mm gap with the calorimeter, contact area of the smallest three points to support the barrel.

Calorimeter inner tube: a metal container for polishing, which can be used to hold an oxygen bomb, which can completely invade the water. The inner tube automatic water flood device, the test water is lacking, the equipment automatically replenished, the volume: 2200ml.

3, mixer, by the constant speed motor drive, heat transfer, avoid calorimeter with outer barrel stirring shaft and the outer barrel touching part quality, the use of thermal insulation gasket, choose the same performance of magnetic stirring device; Stirring power: 3W; Mixing speed inner tube: 375r/min.

4, temperature measuring device: the temperature resolution: 0.0001 ℃, the OMEGA precision PT100 sensors in the United States. Temperature derivative of platinum resistance measured by temperature is 1/1000;

5. Crucible: stainless steel production, distribution two.

6. Timer: record the test time, accurate to S, with an accuracy of 0.1 S/h

7. Power supply: AC185~ 245V.

8. Balance:

A) Analytical balance: the accuracy is 0.1mg

B) Ordinary balance: the accuracy is 0.1g

9. A set of "cigarette" equipment (the tolerance of the mould size of cigarette samples is less than or equal to plus or minus 0.15mm).

10. The crucible method and the tobacco method

11. Total combustion value: > 10kJ/kg

12. Combustion heat value repeatability error: less than or equal to 0.2%

13, temperature measuring range: 0 ~ 50 ℃.

14. Control part (host 1) :

15. Ignition circuit: the voltage 12V is adopted, the adjustable current is 100mA, and the ignition wire is 0.1mm in diameter.

16. Pressure gauges and needle valves: mounted on the oxygen supply back to the road, showing the pressure of oxygen bomb on oxygen filling, accurate to 0.1mpa, oxygen bomb charge oxygen pressure 0 ~ 3.5mpa without air leakage.
