Development of gas turbine abroad

In the early 1940s, gas turbine began to set foot in the field of energy equipment in the power generation industry. After nearly a hundred years of exploration, research and steady development, gas turbine has become one of the main forces of heavy equipment in the field of power generation, and has occupied the dominant position for a long time. In recent years, the core technology of gas turbine has gradually changed to the diversified requirements of low cost, light weight, high power, low pollution, fast start-up and high safety performance.

Throughout the development path and application fields of gas turbine, it can be divided into two categories: the first category is light gas turbine, which is mainly used for industrial power generation, ship propulsion, tank locomotive propulsion, etc.; the second category is heavy gas turbine, which is mainly used for urban public power grid power supply. Statistics and analysis of the growth rate of gas turbine production in the industry in recent years show that the international heavy gas turbine market is almost divided by several foreign power host companies such as GE, siemnes, MHI and ALSTO. In terms of core technology research and development and important parts manufacturing, countries such as Britain, America, Germany and Japan are in the forefront. The advantages and achievements of these countries mainly depend on their long-term R & D investment and technology accumulation in the field of gas turbine.

The world’s first heavy duty gas turbine for power generation was born in Switzerland in 1939. Its birth brought the power generation industry into the era of gas turbine from steam turbine. It is a turning point with era significance and lays the foundation for the development of heavy gas turbine. In the following 70 years of development, heavy duty gas turbine has gone through five development stages: birth, early stage, first stage, second stage and third stage of global market. According to its technical development trend, it can be divided into contemporary stage, advanced stage and future stage. Each stage has different characteristics and applicable conditions.
