Solar and biomass complementary combined cycle power generation system capable of continuous operation throughout the day

Abstract

The invention discloses a solar energy and biomass complementary combined cycle power generating system capable of continuously running all day. Under the adequate light condition, the system directly utilizes high-temperature concentrating solar energy for completing the gasification reaction of solid hydrocarbon fuel by means of a high-temperature rotating type solar energy gasification reactor, and generated synthesis gas is purified and then is conveyed to a combustion chamber of the gas-steam combined cycle power generating system to generate powder; when the light condition is inadequate, the system utilizes a pyrolysis reactor and utilizes high-temperature molten salt storage solar energy for driving the solid hydrocarbon fuel for the pyrolytic reaction, and an atomizer is utilized for atomizing liquid fuel; and the atomized liquid fuel is conveyed to the combustion chamber of the gas-steam combined cycle system for power generation. The requirement that the solar energy is utilized for continuously converting the solid hydrocarbon fuel into the excellent fuel capable of being used by the gas-steam combined cycle system all day, and meanwhile, the system also can be suitable for other kinds of hydrocarbon solid hydrocarbon fuel like coal.

Description

technical field [0001] The invention relates to the technical field of complementary utilization of multiple energy sources, in particular to a solar energy and biomass complementary combined cycle power generation system capable of continuous operation throughout the day. Background technique [0002] In order to cope with the rapid development of economy and modern civilization, the demand for energy will increase year by year. The limited reserves of fossil energy will restrict the development of human civilization. At the same time, problems such as environmental pollution caused by the large-scale burning of fossil energy need to be solved urgently. Therefore, while realizing the efficient and clean utilization of existing fossil energy, vigorously develop clean energy such as solar energy and biomass to gradually replace fossil energy, which has become an important way to solve the current energy and environment coordination and compatibility and realize the sustainable...

Problems solved by technology

[0006] After relevant calculation and simulation analysis, it is concluded that the above-mentioned utilization scheme has great potential in improving the efficiency of solar thermal utilization, but at the same time, we also need to clarify the shortcomings of the above-mentioned technical scheme. Combined with the complementary form of heating compressed air, not only still consume a large amount of fossil energy such as natural gas, but also because the heat collection temperature is too high, it is difficult to realize the complementary operation of the power generation system at night by heat storage

For the complementary way of using high-temperature solar energy to drive biomass gasification to generate electricity, although the system uses clean and renewable energy, it still cannot overcome the problem of high-temperature energy storage
