摘要
设计与开发了松散煤体热物性测试系统。基于热线法测试原理,采用新的数据处理方法,可同时测算材料导热系数λ、热扩散率a和比热容cp;利用PLC结合计算机编程实现数据采集和处理,自动化程度高;实际测试试验表明系统测试结果相对精度高,且与相关文献参照值相符,对于提高松散煤体及其类似材料的热物性测试水平,具有一定价值。
A thermophysic performance measurement and test system of bulk coal was designed and developed.Based on the measurement and test principle of the thermal line law and with the new data processing method,the material heat conducted coefficient λ,the heat proliferation rate a and specific heat volume cp could be calculated simultaneously.The PLC with the computer programming could be applied to the data collection and processing with high automation.The actual test and measurement experiment showed that the t...
