Abstract

The invention belongs to the related technical field of clean renewable energy sources. The invention discloses a solid oxide fuel cell power generation system based on oil fuel. The power generationsystem comprises a solid oxide fuel cell stack, an air heat exchanger, a combustion chamber, a fuel reformer, a steam evaporator and a premixer, wherein the air heat exchanger is connected to a cathode of the solid oxide fuel cell stack, the fuel reformer is connected to an anode of the solid oxide fuel cell stack, and the combustion chamber is connected to a tail gas outlet of the solid oxide fuel cell stack; the combustion chamber is respectively communicated with the air heat exchanger, the fuel reformer and the premixer; the water vapor evaporator is connected to the premixer; tail gas generated by the solid oxide fuel cell stack enters the combustion chamber and is subjected to catalytic combustion in the combustion chamber to obtain hot gas flow, and the hot gas flow enters the air heat exchanger, the fuel reformer and the premixer according to a preset volume ratio. According to the invention, the energy utilization efficiency is improved. The system is simplified.

Description

technical field [0001] The invention belongs to the technical field related to clean and renewable energy, and more specifically relates to a solid oxide fuel cell power generation system based on oil fuel. Background technique [0002] Solid Oxide Fuel Cell (SOFC) has greatly reduced fuel energy loss and air pollutant emissions due to the absence of combustion process, so it has advantages that traditional power generation devices do not have. It is used in portable power generation devices, automotive auxiliary power supplies and distributed Power stations and other fields have broad application prospects. [0003] SOFC has a high energy conversion efficiency and can achieve an electrical conversion efficiency of more than 50%. The quality of waste heat is very high. It can be used in conjunction with gas turbines or steam engines to make the comprehensive fuel utilization rate reach more than 80%. Under the same electric load, the electric efficiency is much higher than ...
