example 1

[0016] Example 1: the present invention has adopted a kind of new calorific value testing device, comprises projectile body 1, and projectile body is the thick-walled cylinder that volume is 300 milliliters; There is deflation valve 3, electrode 4, inflation valve 6 on projectile 2, The electrode 4 is insulated from the warhead 2, and the ignition wire 10 is connected between the inflation valve 6 and the electrode 4. The ignition wire is a nickel-chromium alloy wire with a diameter of 0.1 mm and a calorific value of 3.2 J / cm. Sample 11 is 1.0 g of boron-containing oxygen-poor propellant, which is wound and suspended in the oxygen bomb by ignition wire 10. The distance between the sample and the crucible is 15 mm. The crucible 12 is placed on the crucible frame 13. / carbon composite material, the crucible frame 13 is the upper and lower ring crucible supports of heat-resistant and anti-corrosion nickel-chromium-molybdenum alloy steel, placed on the bottom of the oxygen bomb to...

Abstract

The disclosed installation for testing heat value of propelling agent containing boron and deficient oxygen is to overcome shortcoming in prior art that propelling agent is unable to burn fully, and part of oxidation bomb is ablated. The invention has following arrangement: using thick walled vessel as body, exhaust valve, electrode, and charge valve installed on head; electrode insulated to the head; ignition thread connected between the charge valve and the electrode, and ignition thread being as wire with known heat value; through ignition thread, sample enwound and hung on the oxidation bomb; sample apart from crucible a certain distance; crucible is on rank; additive for combustion with known heat value in specified mass is placed on the crucible. The said additive for combustion guarantees complete combustion of the propelling agent. Since the propelling agent with high heat value does not burn inside crucible totally so as to reduce ablation degree for crucible.

Description

(1) Technical field [0001] The invention relates to a calorific value measuring device, in particular to an instrument for measuring the calorific value of propellant, coal, oil or other exothermic substances in propellant, coal, petrochemical and electric power industries. (2) Background technology [0002] In the prior art, oxygen bomb calorimeters are often used in instruments for measuring the calorific value of substances, wherein the sample combustion chamber is also commonly referred to as an oxygen bomb. 4. Crucible frame 5, intake valve 6, gas charging tube 7, combustion baffle 8, crucible 9. Oxygen enters the oxygen bomb through the intake valve 6 and the inflation tube 7, the gas after combustion is discharged by the deflation valve 3, the electrode 4 is insulated from the warhead 2, and the other electrode is doubled by the intake valve 6 and the inflation tube 7. The sample is placed in the crucible 9, and during the test, it is powered on and ignited so that t...
