Gas Turbine Power Plant, Also Known As Gas Turbine Power Plant Engine

Gas Turbine Power Plant, also known as Gas Turbine Power Plant engine, is a rotary steam power plant. High-temperature and high-pressure steam passes through a fixed nozzle to become an accelerated airflow and is then sprayed onto the blades to rotate the rotor equipped with the blade row and perform work at the same time. Gas Turbine Power Plants are the main equipment of modern thermal power plants and are also used in metallurgical industry, chemical industry, and ship power plants.

In the 1st century AD, the ball turned by the Hero of Alexandria using the reaction force of steam, also known as Fengshen Wheel, was the prototype of the earliest reaction Gas Turbine Power Plant. In 1629, Gde Blanca of Italy proposed a runner rotating by a stream of steam impinging on a blade. In 1882, C.G. Pde Laval of Sweden made the first single-stage impulse Gas Turbine Power Plant of 5 hp (3.67 kW). In 1884, the British C.A. Parsons made the first single-stage reaction Gas Turbine Power Plant of 10 hp (7.35 kW). In 1910, the Swedish B. & F. Junkers Brothers made a radial flow reaction turbine.

At the end of the 19th century, Laval, Sweden and Parsons, England, respectively created practical Gas Turbine Power Plants. Laval produced the first single-stage impulse Gas Turbine Power Plant of 5 hp (3.67 kW) in 1882, and solved the problems related to nozzle design and strength design. Single-stage impulse Gas Turbine Power Plants have very little power and are rarely used.

At the beginning of the 20th century, French Lato and Swiss Zola separately manufactured multi-stage impulse turbines. The multi-stage structure has opened up the way for increasing the power of the Gas Turbine Power Plant, and has been widely adopted, and the power of the unit continues to increase. Parsons obtained a British patent in 1884 and made the first 10-horsepower multi-stage reaction Gas Turbine Power Plant. The power and efficiency of this Gas Turbine Power Plant were leading at the time.

In the early 20th century, Curtis of the United States made multiple speed stages of Gas Turbine Power Plants. Each speed stage generally had two rows of moving blades. After the first row of moving blades, guide blades were installed on the cylinder to guide the air flow to the second row leaf. Speed-level Gas Turbine Power Plants are only used for small-scale Gas Turbine Power Plants, mainly driving pumps, blowers, etc., and are often used as the first stage of small and medium-sized multi-stage Gas Turbine Power Plants.
