Description
Technical Field
The invention belongs to the technical field of thermal power generation systems with high-pressure combustion, and particularly relates to an incomplete cycle power generation system based on oxyhydrogen high-pressure water-doped combustion.
Background
Currently, due to the large amount of greenhouse gases and other emissions generated by various productions and lives of human beings, the global environment and climate are seriously affected, and the scientific community has acknowledged that effective countermeasures should be taken. In the field of thermal power generation, low-carbon energy is one of the future development directions, and hydrogen is highly expected by the society due to high calorific value and zero pollution. However, the equivalent combustion temperature of hydrogen in oxygen is as high as three thousand degrees centigrade, which is far beyond the bearing range of the current materials, so that the hydrogen is generally difficult to be directly utilized. Meanwhile, the price of hydrogen is higher than that of common combustion, and the economic disadvantage is obvious, so that the hydrogen is rarely applied by directly using a combustion mode. With the continuous development of low-carbon energy technology and low-carbon social trend in the future, the maturity of nuclear energy hydrogen production technology, photovoltaic hydrogen production technology and solar thermal hydrogen production technology and the maturity of high-pressure hydrogen storage technology, the possibility of using hydrogen as a power grid energy storage peak regulation medium is increased continuously, the production cost of the hydrogen is reduced remarkably, and the possibility is provided for the large-scale utilization of the hydrogen.
The traditional large-scale and high-efficiency power generation mode based on fuel combustion generally adopts a gas-steam combined cycle mode, and the cycle efficiency of the mode is about 60 percent (the efficiency of a common non-combined cycle mode is about 40 percent). The main reason for the higher efficiency is that the hot end temperature of the gas turbine is as high as 1300 ℃ or more, while the cold end temperature is the same as that of the condensing turbine. However, because the exhaust temperature of the gas turbine is about 500-600 ℃, high-pressure steam needs to be generated again by a waste heat boiler and the like to be used by the steam turbine for doing work, the overall cycle efficiency is difficult to further improve due to different gas and steam media and the problem of heat transfer temperature difference, the difference from the Carnot cycle theoretical efficiency is large, and the defect of complex system exists. It is clear that the above-mentioned combined gas-steam cycle has the disadvantage that the process of applying work to the same turbine (gas turbine section and steam turbine) has to be carried out with two working fluids, between which heat is exchanged with a heat exchanger. Meanwhile, because the temperature of a hot end part is cooled by gas in the existing gas turbine, on one hand, the cooling capacity of the gas is limited, and the hot end temperature is limited to be further increased; on the other hand, the consumed gas also has a negative influence on the improvement of the overall efficiency.
