Embodiment 1

[0045] Such as figure 1 As shown, a schematic flow chart of a Britton combined cycle power generation device with solar heating of the present invention.

[0046] A Breton combined cycle power generation device with solar heating, which uses the high-temperature flue gas discharged from the gas turbine in the top Breton cycle as the heat source of the bottom Breton cycle, and recovers the waste heat of the flue gas discharged from the top cycle, After being heated up by the cavity receiver of the solar heat concentrating device, it is used for bottom cycle power generation, thereby forming a Breton combined cycle power generation system with solar heating, which is characterized in that:

[0047] The top Breton cycle refers to that the combustion-supporting air 10 is pressurized by the top cycle compressor 11 to form top cycle compressed air 12, which is sent into the combustion chamber 14 and mixed with fuel 13 for combustion, and the formed high-temperature flue gas 15 is se...

Abstract

The invention relates to a Britten combined cycle power generation device with solar energy heating. The device adopts an operation method in which top Britten cycle and bottom Britten cycle are combined; the flue gas of relatively high temperature exhausted from the gas turbine in the top Britten cycle is used as the heat source of the bottom Britten cycle; the bottom cycle adopts air as the working medium for recycling the waste heat of the high-temperature flue gas exhausted from the gas turbine; the working medium is then heated through the cavity type receiver of a solar energy heat gathering device and used for bottom Britten cycle power generation. According to the device, the thermal energy generated from fuel combustion is reasonably utilized; meanwhile, the heat of the solar energy is effectively utilized and the purposes of saving energy and reducing energy consumption are realized and the device is particularly suitable for drought areas to use.

Description

technical field [0001] The invention relates to a Breton combined cycle power generation device with solar heating, specifically belonging to the technical field of gas turbine power generation devices. Background technique [0002] Advanced gas turbines are the core key equipment of energy and power systems in the 21st century, and they are also an important symbol of the advanced level of a country's industrial foundation in the world. The development of advanced gas turbine technology has great strategic significance and broad prospects for industrialization, and plays an extremely important role in the development of high-tech in related fields in our country. [0003] Large-capacity, high-efficiency gas turbines and their combined cycles have become an inevitable trend, and their share in the world's power generation capacity has grown significantly and rapidly. In recent years, a kind of distributed energy system and power supply device with small and micro gas turbin...
