Fuel oil supply system and power generation system of power plant boiler

The utility model provides a fuel oil supply system and a power generation system of a power plant boiler, the fuel oil supply system comprises a buffer tank, an oil supply pipeline and a fuel oil feeding pipeline, the outlet of the oil supply pipeline is communicated with the buffer tank to convey fuel oil into the buffer tank, and the outlet of the fuel oil feeding pipeline is communicated with the buffer tank. An inlet of the fuel oil feeding pipeline is communicated with the buffer tank so as to feed the fuel oil in the buffer tank into a boiler through the fuel oil feeding pipeline; a valve mechanism and a filter are connected in the oil supply pipeline in series, fuel oil flows to the buffer tank after flowing through the filter and the valve mechanism, and the technical problem that long-time stable and smooth fuel oil supply of the power plant boiler is difficult to guarantee is solved. 本实用新型提供了一种电厂锅炉的燃油供应系统及发电系统，燃油供应系统包括：缓冲罐、供油管路和燃油送入管路，所述供油管路的出口与所述缓冲罐连通以向所述缓冲罐内输送燃油，所述燃油送入管路的入口与所述缓冲罐连通以通过所述燃油送入管路将所述缓
