这段煤气化的东西如何理解啊? The pilot air block valve and the pilot gas double-block and vent valves on the route selected (pilot 1 or pilot 2) are opened. The selected igniter is operated for a timed period of 10 seconds. The operator must confirm that he has seen the pilot burner ignite during the timed period, “CONFIRM”, for pilot lit, will terminate this stage and ascend to 3e). No input will terminate this stage and return to 1, RESET on timeout. 请懂行的人帮理解下?非常感谢~!查看更多1个回答 . 4人已关注
