Abstract

The invention discloses a disc type hybrid solar photo-thermal and natural gas power generation system which comprises a gas turbine power generation system, a waste heat boiler, a disc type solar photo-thermal conversion system and a turbine, wherein the turbine is connected with a second electric generator, a gas turbine smoke exhaust system is communicated with a smoke and afterburning system of the waste heat boiler, a main steam outlet of a steam-water system of the waste heat boiler is connected with a steam inlet system of the turbine, and supplemented water of the whole directly enters a condenser. According to the system disclosed by the invention, a natural gas power generation system and a disc type solar photo-thermal power generation system are organically combined together for generating power, and meanwhile, steam can be supplied to the outside according to requirements. With the hybrid power generation system, electrical load can be adjusted to satisfy the demand for electric power supply, alleviate power supply pressure, and reduce consumption of gas, the problem that the disc type solar photo-thermal power generation system can not store energy at night is solved, the cost input is reduced, and meanwhile, the disc type hybrid solar photo-thermal and natural gas power generation system can continuously run all the rear round, so that the overall economic benefit of a project is improved.

Description

technical field [0001] The invention relates to a power generation system, in particular to a dish-type solar thermal and natural gas combined power generation system. Background technique [0002] Natural gas power generation is one of the most stable distributed energy supply methods. An excellent combined cooling, heating and power generation system can increase the efficiency of gas power generation to over 95%. From the development experience of developed countries in the world and some Southeast Asian countries, the development of distributed gas-fired power generation systems is the only way to achieve energy conservation, emission reduction and sustainable development of energy supply. It is an irreversible trend in the development of the modern energy field, and it is the most promising way of energy supply. [0003] However, natural gas resources are non-renewable energy sources that are easily consumed after all, and natural gas resources are not inexhaustible, s...

Problems solved by technology

[0004] Solar energy is an inexhaustible and best renewable energy all over the world, but the use of solar energy resources also has its constraints, the biggest constraint is that solar energy can only be used in sunny days during the day, It cannot be used on cloudy days and at night, which leads to discontinuity in energy utilization

In order to realize the continuous power generation of solar energy, it needs to spend huge financial resources to build a huge energy storage system. Not only the equipment and materials used for energy storage are very expensive, but also there are various constraints that are not easy to realize, and the realization is relatively difficult.

For example, the solar dish power generation system needs to use some kind of gas, liquid, etc. as the intermediate circulation medium, and ceramics, molten salt and other materials are used as the energy storage medium. Invisibly, two more circulation systems and equipment are added. The system is complex and engineering Bulky, expensive materials, high power consumption
