Embodiment Construction

[0056] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0057] In one aspect, the present invention provides a method of generating electricity, see below Figure 1-Figure 3 The power generation method of the present invention is described.

[0058] (1) Power generation method 1

[0059] The present invention provides a power generation method, because figure 1 Shown is an example of a power generation system used in this power generation method, so for ease of understanding, see below figure 1 Describe the generation method,

[0060] Specifically, see figure 1 , the power generation method includes: storing the compressed gas in the underground gasification burn-out area 13 through, for example, the compressor 1; taking out the compressed mixed gas containing the compressed gas from the underground gasification burn-out area 13; The gas is divided into two paths, one of which is sent into the combust...

Abstract

An electricity generating method comprises storing a compressed gas in an underground cavity, taking out a compressed mixed gas containing the compressed gas from an underground gasification cavity, sending the compressed mixed gas into a combustion chamber, and/or sending the compressed mixed gas to an underground gasification furnace for generating a combustion gas and sending to the combustion chamber. An electricity generating system comprises a compressor with an gas exhaust opening, an underground gasification furnace with a gas inlet well and a gas outlet well, a gas turbine, a combustion chamber, and an underground gasification cavity with a storage gas inlet and a storage gas outlet; or, the gas exhaust opening is communicated with the storage gas inlet, the storage gas outlet is communicated with the combustion chamber and the gas inlet well, and the gas outlet well is communicated with the combustion chamber; or, the gas exhaust opening is communicated with the storage gas inlet and the gas inlet well, the storage gas outlet is communicated with the combustion chamber, and the gas outlet well is communicated with the combustions chamber; or, the gas exhaust opening is communicated with the storage gas inlet and the combustion chamber, the storage gas outlet is communicated with the gas inlet well, and the gas outlet well is communicated with the combustion chamber. The electricity generating method and the electricity generating system realize electricity generating, and also realize treatment on pollutants in the underground gasification cavity.

Description

technical field [0001] The invention relates to a power generation method and a power generation system. Background technique [0002] Compressed gas energy storage power station is a new type of energy storage power station. It uses the excess electric energy of the power system when the capacity load is low to compress the air and store it in the underground cavern, and then release it when needed, and then generate electricity through the gas turbine generator set after heating to meet the needs of peak load. The energy supplied to the gas turbine is the sum of the potential energy of the compressed air and the chemical energy of the fuel used to heat the air. A compressed air energy storage plant generates more electricity than is required for charging in a cycle of charging and discharging. The ratio of charging and discharging energy is called the power ratio, which is generally 0.72 to 0.80, and it depends on the scale and design of the power station. In the proces...
