3）关键技术说明

加热炉及转油线：本装置共有两台加热炉,均采用圆筒炉：常压炉和减压炉。两炉均为辐射-对流型圆筒炉。两炉共用一套余热回收系统。炉烟气汇集至地面，经热管式空气预热器降温后，由引风机排入独立的60m高烟囱，排放至大气。空气预热器将冷空气加热后，送至燃烧器供燃烧用。炉子热效率达90%以上。

常压炉正常工况下热负荷~19.8MW。炉管为四管程。炉管的规格均为Ф168×8。炉管材质大部分为1Cr5Mo,每管程辐射段出口有4根炉管，采用0Cr17Ni12Mo2。辐射炉管直段长15m, 共88根；对流炉管每排8根，共18排，对流炉管的有效长度为6.95m。

加热炉温度TE-2005A/B（其中一支备用，由DCS软开关选择用那一路控制）为主回路PID为TIC-2005，然后取四点炉膛温度TI-2004A—D（四个温度）的平均值作为副回路，控制进加热炉燃料油流量阀或者燃料气流量阀（由DCS软开关选择，看工艺用哪种介质而定）
