Prospects For The Development Of Gas Turbine Power Plants

Prospects for the development of Gas Turbine Power Plants

The emergence of Gas Turbine Power Plants has promoted the development of the power industry. By the early 20th century, the power of Gas Turbine Power Plants in power stations had reached 10 MW. With the increasing application of electric power, the peak load of power plants in New York City and other large cities in the United States was close to 1000 MW in the 1920s. If the stand-alone power is only 10 MW, nearly 100 units need to be installed, so the stand-alone power has increased in the 1920s As large as 60 MW, 165 MW and 208 MW Gas Turbine Power Plants appeared in the early 1930s.

Since the economic recession and the outbreak during World War II, the increase in the power of the Gas Turbine Power Plant is at a standstill. In the 1950s, with the post-war economic development, the demand for electricity was surging, and the power of the single unit began to increase continuously. Large Gas Turbine Power Plants of 325 to 600 MW appeared one after another; 1000 MW Gas Turbine Power Plants were made in the 1960s; 1300 MW Gas Turbine Power Plant. The stand-alone power commonly used in many countries is 300-600 MW.

Gas Turbine Power Plants are widely used in various sectors of the social economy. There are many types of Gas Turbine Power Plants, and there are different classification methods. The steam of the Gas Turbine Power Plant expands from the inlet to the outlet, and the volume of steam per unit mass increases hundreds of times, or even thousands of times. Therefore, the blade height of each level must be lengthened step by step. The high-power condensing Gas Turbine Power Plant requires a large exhaust area, and the last stage blades must be made very long.

The development of large-scale Gas Turbine Power Plant units is an important direction for the future development of Gas Turbine Power Plants. Among them, the development of longer last-stage blades is a key to the further development of large-scale Gas Turbine Power Plants; research on improving thermal efficiency is another direction for the development of Gas Turbine Power Plants. Higher steam parameters and Secondary reheating, the development of peak shaving units, and the promotion of the application of heating Gas Turbine Power Plants are important trends in this regard.
