硼烷合乙二胺的点火、燃烧及热解特性
Ignition, Combustion and Pyrolysis Characteristics of Ethylenediamine Bisborane
摘要
Abstract
To explore the combustion characteristics of ethylenediamine bisborane hydrogen storage material with high hydrogen content in air, the ethylenediamine bisborane micro particles were prepared by a gas phase synthesis method. Its ignition and combustion parameters were tested by a continuous laser ignition test. The mechanism of combustion process was studied by pyrolysis experiments in nitrogen and air. The results show that ethylenediamine bisborane has the characteristics of short ignition delay time and small ignition energy. In a stagnation air flow at atmospheric temperature and pressure, as ignition power density reaches the order of magnitude of 109W/m2, the ignition delay time of micro ethylenediamine bisborane is 0.0002-0.0009s and minimum ignition energy is 0.0001J. The continuous laser ignition combustion process is divided into two stages, which produce bright blue flame and yellow flame, respectively. Combined with the pyrolysis behavior of materials in nitrogen and in air, it can be inferred that blue flame results from the combustion of hydrogen released in the first stage, and yellow flame shown in the second stage results from the combustion of pyrolysis products at higher temperature.关键词
