Solar high-temperature heat collecting and storage gas turbine power generation device

Abstract

The invention relates to the technical field of energy, and discloses a solar high-temperature heat collecting and storage gas turbine power generation device. The solar high-temperature heat collecting and storage gas turbine power generation device comprises a combustion chamber, a solar heat collector, a chemical heat storage tank, a three-way valve A and a three-way valve B. The chemical heatstorage tank is provided with a high temperature side and a low temperature side. One outlet of the three-way valve A is connected with a compressed air inlet of the solar heat collector, and the other outlet of the three-way valve A is connected with an inlet of the three-way valve B. One outlet of the three-way valve B is connected with the low temperature side of the chemical heat storage tank,and the other outlet of the three-way valve B is connected with an inlet of the combustion chamber. A compressed air outlet of the solar heat collector is connected with the high temperature side ofthe chemical heat storage tank and the inlet of the combustion chamber, and the low temperature side of the chemical heat storage tank is also connected with the inlet of the combustion chamber. The solar high-temperature heat collecting and storage gas turbine power generation device consumes less fossil fuel, is longer in service life and has better on-grid electricity quality.

Description

[0001] The present invention claims the priority of a Chinese invention patent application whose application number is CN 201610668545.9, and whose application date is August 12, 2016. technical field [0002] The invention relates to the field of energy technology, in particular to a solar high-temperature heat collection and heat storage gas turbine power generation device. Background technique [0003] The total global solar radiation is about 1.7×10 17 W, of which my country accounts for about 1% (1.8×10 15 W, equivalent to 1.9 trillion tons of standard coal per year), is about 700 times the current annual energy consumption in my country, and solar energy has huge development potential. The use of solar energy, a clean and non-polluting renewable energy source, is of great significance for alleviating the current pressure of fossil energy and environmental pollution. [0004] There are two main types of solar power generation technologies: photovoltaic and phototherma...

Problems solved by technology

[0006] However, as mentioned above, due to the relatively low density of solar energy flux, the energy fluctuation is relatively large

When the sunlight is strong, it may cause the collector temperature to be too high and reduce its operation stability

When the sunlight is insufficient, the temperature of the compressed air entering the combustion chamber is not enough, and it is difficult to achieve the technical effect of saving energy.
