具体的
烟气流程:
天然气进入内燃机做功发电后,产生约360℃的烟气,进入余热锅炉2的蒸发器21,省煤器23,热水加热器后通过烟囱排出
水循环流程:
内燃机缸套水与外部水通过缸套水板式换热器15换热降温后做闭式循环,缸套水从90℃降至70℃,外部水从68℃降至88℃。88℃的外部水进入余热锅炉2热水加热器升温至95℃后,进入膨胀罐7,一路进入丙酮换热器9,降温至88℃,再分别进入盐水换热器11和制冷机。回水与补水混合后回到缸套水板式换热器15进行升温,以此循环,补水是大工业水进入软化水处理器12,再进入水箱,通过水泵与回水管混合。
蒸汽流程:
厂区内130℃的热水通过闪蒸罐5产生0.02MPa的蒸汽,进入除氧器4进行除氧,余热锅炉2产生的蒸汽外供生产使用。进入膨胀罐7的另一路通往除氧器4,经过除氧器4的水流由锅炉给水泵6输送至省煤器23,再进入蒸发器21,通过蒸发器21并进入汽包22,最后从汽包22上端的蒸汽出口排出,供生产所需。
