Abstract: In order to make full use of the high temperature exhaust gas of the main generator and realize energy saving and emission reduction, the waste heat recovery unit has been designed in the basic design stage in “Hai Yang Shi You 123”FPSO(Floating Production Storage and Offloading), but the waste heat and the heating medium circulation system of the boiler are completely independent, and can not be mutually standby, and the four heating medium circulation pumps of the waste heat are not connected to the emergency bus, which will lead to the black start of the FPSO. It is easy to cause local high temperature coking and carbonization of heating medium in the furnace tube of waste heat recovery unit, which affects the operation of the system. In order to solve the problem effectively, the scheme of adding the circulating pump of waste heat system into the emergency bus bar is proposed creatively, which can effectively avoid the occurrence of heating medium coking in the waste heat system during black start.
