1、重油电站包括的系统？
答：1、发电机组；2、启动系统（压缩空气启动）；3、冷却系统（水多采用冷却塔，前提成本低；水少或者沙漠地区采用散热器，前期成本高）；4、电气及控制系统；5、燃油处理和滑油处理系统；6、卸油泵站（重油和柴油）；7软水装置（如当地水质差）；8、机械安装材料；9、电气安装材料；10、油罐系统（大型油罐一般是半成品集装箱运输，现场焊接；油漆区管道、传感器、液位计、电线、油罐保温）。
2、重油电站的交货期？
答：20MW以内一般为6个月，重油分离机核心零部采用进口周期需要近6个月，发电机组***台完成约4个月，因为交流发电机的交货期为4个月，发动机为我公司生产或者库存，一般2-3个月内完成***台。
3、质保期是多久？
答：出厂12个月或运行2000小时，先到位准。
4、电站建设周期？
答：从合同签订到***台开始发电最快10个月，发电机组及附属设备生产周期6个月，运输1-1.5个月，安装调试3个月，一共最少10个月。
5、指导安装
答：一般电站会至少派1个电气工程师和1个机械工程师，如包括油罐系统，还会派1个油罐指导技术员，较大型电站安排1位项目工程师，所以，一般2-6人之间。
6、重油和柴油的发电成本比较
答：按非洲地区油价，一般而言，重油发电综合成本约0.82元/度电，柴油约1.5元/度电（部分老板反馈实际达到了2元/度电）。
