采用微量热仪器针对自燃倾向的测试
|
| Materials such as coals, coal products (e.g., chars, briguettes) and activated carbons are a self-heating hazard in storage and transportation. Accordingly, work was carried out in the 1970’s largely at the Fire Research Station in the UK, which led to the formulation of a test for predicting whether or not a particular coal or carbon material was a self-heating hazard. The test which is very widely used up to the present time, focuses on the quantity critical ignition temperature, and the present author has shown that this is not the most suitable quantity around which to build such a test. The critical ignition temperature provides an indication of self-heating hazards only in the limit where all susceptible materials have the same activation energy (usual symbol E, units J mol-1) for their reaction with atmospheric oxygen. This is very far from the truth, and consequently the tests are unreliable. |
