1试验开展1.1试验设备调试及改造本项工作主要采用高温高压釜作为试验设备(图1),为开展3个高压釜在同一压力下的实验,首先对高压釜的电加热系统、控制系统、密封及气路系统进行了检查与调试;然后对高压釜进行适当改造,安装了连通管道(图1)。因高压釜长期未使用,沾染了灰尘及少量铁锈,在开始试验前应先对高压釜进行仔细清洗,主 1 test carried out 1.1 test equipment commissioning and modification This work mainly uses the high-temperature autoclave as a test equipment (Figure 1), in order to carry out the experiment of the three autoclaves under the same pressure, first of all, the autoclave electric heating system, control system, Sealing and gas system were checked and debugged; the autoclave was then properly modified and a connecting pipe installed (Figure 1). Due to the long-term unused autoclave, contaminated with dust and a small amount of rust, before starting the test should be carefully cleaned the autoclave, the main
