Abstract

The invention relates to an energy-saving fuel system for a thermal power plant. The energy-saving fuel system comprises fuel tanks, fuel supply pumps, a fuel gun and a fuel supply mains and a fuel return mains of the fuel gun. A fuel channel pressurizing device is connected between outlets of the fuel tanks and the fuel supply mains, a first adjusting valve is arranged on a pipeline between fuel outlet ends of the fuel supply pumps and a fuel outlet end of the oil channel pressurizing device, the fuel return mains is provided with a second adjusting valve, and the fuel channel pressurizing device comprises a fuel energy storage tank and a fuel pressure pump. The fuel system for the thermal power plant keeps fuel pressure stable on the premise of no spinning reserve of the fuel supply pump, energy resources are saved, and the problem that fuel temperature rises to exceed flammability point is avoided.

Description

technical field [0001] The invention relates to an energy-saving fuel oil system in a thermal power plant. Background technique [0002] The fuel oil system of coal-fired thermal power plants is used for boiler ignition and stable combustion. The current problem is that the fuel system still needs to maintain normal operation when the boiler is burning stably and does not need oil to support combustion, so as to deal with the unstable combustion that may occur at any time. The long-term operation of the fuel supply pump in the fuel system will cause a lot of useless energy consumption. The useless energy consumption will be dissipated in the form of heat, which will make the fuel supply pump heat up and eventually cause the temperature of the fuel to rise, especially in summer when the oil temperature often exceeds #0. point, the risk increases significantly. Contents of the invention [0003] The purpose of the present invention is to provide an energy-saving fuel oil s...
