Abstract

The invention relates to a supercritical one-time diverting type longitudinal three-stage Rankine cycle power generation system. The system comprises an LNG (liquefied natural gas) circulating pump and a sea water pump and also comprises a primary power generation unit, a secondary power generation unit and a tertiary power generation unit which are sequentially distributed in longitudinal arrays,wherein the primary power generation unit comprises a primary evaporator, a primary steam turbine, a primary condenser and a primary working medium pump which are connected sequentially to form a closed loop; the secondary power generation unit comprises a secondary evaporator, a secondary steam turbine, a secondary diverter, a secondary condenser, a secondary mixer and a secondary working mediumpump which are connected sequentially to form a closed loop; the tertiary power generation unit comprises a tertiary evaporator, a tertiary steam turbine, a tertiary diverter, a tertiary condenser, atertiary mixer and a tertiary working medium pump which are connected sequentially to form a closed loop. The supercritical one-time diverting type longitudinal three-stage Rankine cycle power generation system has the advantages as follows: the system is simple in structure, convenient to use and capable of being widely used in LNG cold energy power generation field.

Description

Technical field [0001] The invention relates to the technical field of LNG cold energy power generation, in particular to a supercritical primary split type longitudinal three-stage Rankine cycle power generation system. Background technique [0002] Natural gas has become the fastest growing fuel in the world due to its high efficiency and cleanliness. However, the liquefaction of natural gas requires large amounts of electricity. There is a huge temperature difference between the LNG and the ambient temperature at the receiving terminal, and there is a large amount of available cold energy. Since LNG-FSRU usually stays on the sea far away from land users, in order to smoothly transport natural gas to users through pipelines, the NG outlet pressure in the FSRU system is usually higher than that of the land IFV system. According to the US LNG transmission pressure requirements, long-distance natural gas transportation must reach more than 7MPa. At this time, LNG has reached a su...
