What Is a Turbo Generator?

Conventional gas turbine generators are typical examples of large-scale power generation equipment and can provide power from 1 to several megawatts.

Basic knowledge of gas turbine generators: It can meet the electricity needs of almost all buildings including office buildings, hospitals, schools, and shops. The exhaust gas from the turbine generator is an ideal heat source for absorption refrigerators, which are used for cooling, heating and providing sanitary hot water. Because compared with the exhaust gas from coal-fired power plants, the impurities and sulfur content of the exhaust gas are very low, and the most significant is that its oxygen content is higher, which can reach more than 15%, which can be used as combustion air for direct combustion engines. Second combustion. Gas turbine generators are often used as peak shaving during summer power spikes. However, due to the high temperature in summer, the output of gas turbines is seriously insufficient and the efficiency is reduced. Therefore, the lithium bromide refrigerator cools the inlet of the turbine generator by using the exhaust gas refrigeration of the turbine generator, which can greatly improve the output and efficiency of the turbine generator. It has proven to be a very effective way to save energy. Turbine generators are usually made up of

At present, gas turbine power generation technology has been popularized in major thermal power plants in China. However, the maintenance issues that gas turbines must face during use are not optimistic. Because the cleanliness of natural gas may not be effectively controlled, impurities in natural gas can easily accumulate in the compression chamber and even corrode the base metal. Many times, manufacturers must go through a filtering process before introducing gas turbine combustion. Despite filtering, the accumulation of impurities and corrosion of the base metal still exist in the compression chamber. Therefore, the gas turbine must be cleaned regularly. Otherwise, the efficiency of the gas turbine will gradually decrease and affect the service life. However, the traditional high-pressure gas and high-pressure water flushing effect is not significant. For a long time, this situation was helpless. However, recently, the global chemical supplier giant CHEMETALL has developed a compressor cleaning agent for gas turbines that can be effectively cleaned without corroding the base metal and without disassembling it. It is said that some foreign power plants have already been used, and the effect is remarkable.

In the 12th century AD of the Southern Song Dynasty, Gao Zong had a record of marquees. It is

The working process of a gas turbine is that a compressor (that is, a compressor) continuously sucks air from the atmosphere and compresses it; the compressed air enters the combustion chamber, mixes with the injected fuel, and burns to become high-temperature gas, which then flows into the gas permeable The expansion expands to perform work in the medium, pushing the turbine impeller to rotate with the compressor impeller; the working capacity of the heated high-temperature gas is significantly improved, so while the gas turbine drives the compressor, there is still work to do as the output mechanical work . When the gas turbine is started from a standstill, the starter is required to rotate with the starter, and the starter will be disengaged only after it is accelerated to run independently.
The working process of a gas turbine is the simplest, called a simple cycle; in addition, there are a regenerative cycle and a complex cycle. The working fluid of the gas turbine comes from the atmosphere and is finally discharged to the atmosphere. It is an open cycle; in addition, there is a closed cycle where the working fluid is used in a closed cycle. The combination of gas turbine and other heat engines is called a compound cycle device.
The initial gas temperature and the compression ratio of the compressor are the two main factors affecting the efficiency of the gas turbine. Increasing the initial temperature of the gas and correspondingly increasing the compression ratio can significantly improve the efficiency of the gas turbine. At the end of the 1970s, the compression ratio reached a maximum of 31; the initial gas temperature of industrial and marine gas turbines was as high as about 1200 ° C, and that of aviation gas turbines exceeded 1350 ° C. ^[1]
