Abstract

The invention discloses an in-plant comprehensive utilization system and method for natural gas pressure energy of a combined cycle power plant. The system comprises a natural gas power generation/refrigeration system, an in-plant comfort cooling system, a circulating cooling water heat exchange system and a gas turbine. The natural gas power generation/refrigeration system and the gas turbine areconnected in parallel and are both connected with a natural gas pipeline. A gas outlet of the natural gas power generation/refrigeration system is connected with a gas inlet of the gas turbine. Electric energy generated by the natural gas power generation/refrigeration system is used for providing electric energy, and prepared cold water is connected with the in-plant comfort cooling system and the circulating cooling water heat exchange system. According to the system, the back pressure of a steam turbine can be reduced, the output of the steam turbine can be improved, and finally comprehensive utilization of the energy is achieved.

Description

technical field [0001] The invention belongs to the field of utilization of natural gas residual pressure in combined cycle power plants, and relates to a system and method for comprehensive utilization of natural gas pressure energy in combined cycle power plants, in particular to a method for fully utilizing the residual pressure of natural gas in combined cycle power plants for power generation and refrigeration, and in-plant Comprehensive utilization of energy systems. Background technique [0002] The natural gas in the pipeline network is generally transported in the form of high pressure. When it reaches the combined cycle generator set, it often needs to be depressurized. The pressure energy generated during the depressurization process can be considered to be recycled. At present, the commonly used methods of recovery and utilization of pressure energy in natural gas pipeline networks include power generation and refrigeration. The basic principle of natural gas pi...
