These vibrations are caused by interactions between the combustion process, the flow of the fuel-air mixture and the acoustic properties of the combustion chamber.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">During combustion, periodic pressure changes can occur, which are manifested as <strong>Acoustic or thermoacoustic vibrations<\/strong> in the combustion chamber. If these vibrations are additionally stimulated or amplified by the combustion process, stable resonances can form. In such cases, one often speaks of <strong>Combustion instabilities<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Combustion chamber vibrations can have a significant impact on the operation of gas turbines. Excessive pressure vibrations can, for example, lead to <strong>Increased mechanical stress on components, material fatigue, loss of performance or increased wear<\/strong> lead to vibrations. Continuous monitoring of these vibrations is therefore an important part of the <strong>Diagnosis and optimization of combustion processes<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In practice, combustion chamber vibrations are often <strong>dynamic pressure sensors<\/strong> measured and evaluated. Measurement data acquisition systems - for example from Delphin Technology - enable the <strong>High-resolution detection and analysis of such fast pressure signals<\/strong>, to detect combustion instabilities at an early stage and optimize the operation of gas turbines.<\/p>","protected":false},"featured_media":0,"template":"","class_list":["post-6755","glossar","type-glossar","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.delphin.de\/en\/wp-json\/wp\/v2\/glossar\/6755","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.delphin.de\/en\/wp-json\/wp\/v2\/glossar"}],"about":[{"href":"https:\/\/www.delphin.de\/en\/wp-json\/wp\/v2\/types\/glossar"}],"wp:attachment":[{"href":"https:\/\/www.delphin.de\/en\/wp-json\/wp\/v2\/media?parent=6755"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
