姚孟发电有限责任公司是全部由亚临界参数机组组成的百万级火力发电厂。1、2号机组是20世纪70年代初我国自行设计、制造的第一批30万千瓦发电机组，操作以人员手动操作为主，整体水平比较落后。姚电人20年来，不断地进行技术改造，从初始阶段的“礼拜机”、“探亲炉”返厂修理 Yaomeng Power Generation Co., Ltd. is a million-level thermal power plant that consists of subcritical parameters. Units 1 and 2 were the first 300,000-kilowatt generating units that were designed and manufactured by China in the early 1970s. The operations were mainly manual operations and the overall level was relatively backward. In the past 20 years, Yaodian people have been constantly carrying out technological transformations. They have returned to the factory for repairs from the “launch machine” and “home-baking oven” at the initial stage.
