Identificare le oscillazioni acustiche prima che causino danni ai componenti della turbina

Per oltre 50 anni, PCB® si è specializzata nella progettazione e produzione di sensori e sistemi di misura innovativi per il mercato delle turbine a gas. In questi cinque decenni, la nostra esperienza nella strumentazione per la dinamica della combustione ha soddisfatto i requisiti più esigenti del settore per la misurazione dinamica della combustione e il monitoraggio dei motori a turbina.

Con l'obiettivo di aumentare l'efficienza del carburante e ridurre le emissioni di scarico, i motori a turbina a gas di oggi si basano sull'innovazione tecnologica, ma comportano anche potenziali problemi. La combustione di una fiamma più magra mantiene basse le emissioni di NOx, ma allo stesso tempo aumenta l'instabilità (dinamica della combustione) nel motore a turbina a gas. Questa instabilità può danneggiare i componenti della camera di combustione, come gli ugelli, i cestelli e i pezzi di transizione, nonché i componenti a valle, come le pale, con conseguenti tempi di fermo e perdite di profitto.

PCB offre un'ampia gamma di sensori di pressione e vibrazione per monitorare la dinamica di combustione di una turbina a gas, al fine di identificare e correggere le oscillazioni acustiche prima che causino danni.
