Aeroderivative gas turbines are rotating thermal engines whose main use is in cogeneration, in other words, the simultaneous generation of electrical and heat energy. Smaller than combined cycle turbines, they are used in industrial processes that require the generation of both energy sources - electricity and heat - and their operating strategy is continuous. Therefore, start-ups and shutdowns severely impact the whole system. Furthermore, they necessitate stopping the associated industrial process, with the financial losses that entails. That is why it is essential to minimize unwanted start-ups and shutdowns. In this article we give you 4 tips which may help to prevent wear on Gas turbines.
