摘要:
利用FLACS软件分析初始压力、初始温度对CH4/CO2/air混合气的爆炸温度、最大爆炸压力的影响;并与计算值对比。结果表明:①初始压力对爆炸温度、爆炸前后压力比影响可以忽略。常温变压条件下二氧化碳浓度增加,爆炸温度与爆炸前后压力比基本呈线性降低。常压变温条件较复杂,二氧化碳浓度升高爆炸温度降低;初始温度对低浓度(<15%)二氧化碳混合气爆炸温度几乎没有影响,而高浓度(>15%)二氧化碳混合气爆炸温度随初始温度增加而升高;最大爆炸压力随二氧化碳浓度以及温度升高而降低。②在设定条件下,低浓度(5%~10%)二氧化碳混合气爆炸温度计算值与模拟值相对误差小于5.5%,吻合较好;最大爆炸压力计算值与模拟值相对误差在6.5%~10.5%之间。
Abstract:
FLACS software was used to analyze the influence of initial pressure and initial temperature on the explosion temperature and the maximum explosion pressure of CH4/CO2/air mixed gas, and the results were compared with the calculation values. It showed that the influence of initial pressure on the explosion temperature and the rate of pressure before and after explosion can be ignored. Under the conditions of normal temperature and different pressure, with the increasing concentration of carbon dioxide, the explosion temperature and the rate of pressure before and after explosion reduce linearly. The situation under the conditions of normal pressure and different temperature is more complex, with the increasing concentration of carbon dioxide, the explosion temperature reduces. The initial temperature has almost no effect on the explosion temperature of mixed gas with low concentration (less than or equal to 15%) of carbon dioxide, while the explosion temperature of mixed gas with high concentration (higher than 15%) of carbon dioxide increases with the increase of initial temperature. The maximum explosion pressure decreases with the increase of carbon dioxide concentration and temperature. Under the setting conditions, the relative error of calculation value and simulation value for the explosion temperature of mixed gas with low concentration of carbon dioxide is less than 5.5%, which is in good agreement. The relative error of calculation value and simulation value for the maximum explosion pressure is between 6.5%-10.5%.
