PRECURSOR - Early Warn­ing Sys­tem for Com­bus­tion Dy­nam­ics

The IfTA PreCurs­or for com­bus­tion dy­nam­ics is an early warn­ing sys­tem for gas tur­bines to pre­vent dam­age due to com­bus­tion dy­nam­ics, par­tic­u­larly in an­nu­lar com­bus­tion cham­bers of gas tur­bines.

Ad­vant­ages of the pre­curs­or com­pared to con­ven­tion­al solu­tions

So far pro­tec­tion sys­tems are based on de­tec­tion of grow­ing com­bus­tion dy­nam­ics. Until the gas tur­bine con­trol­ler re­acts, dam­aging com­bus­tion dy­nam­ics may occur over ex­ten­ded time peri­ods. On the other hand, the new model-based IfTA PreCurs­or iden­ti­fies de­creas­ing sta­bil­ity dir­ectly, that is, be­fore any sig­ni­fic­ant os­cil­la­tion ap­pears. This means a con­sid­er­able im­prove­ment in ma­chine pro­tec­tion: With the IfTA PreCurs­or gas tur­bines can run in a most stable, clean and ef­fi­cient way even over a wide load range.

Detect dan­ger­ous com­bus­tion dy­nam­ics with the Pre­curs­or early warn­ing sys­tem:

  • Detect flame in­stabil­it­ies be­fore high amp­litudes occur
  • Avoid dam­age
  • Cost sav­ings through stable, clean and ef­fi­cient op­er­a­tion over a wide load range

The IfTA PreCurs­or is avail­able as a soft­ware mod­ule for the IfTA Ar­gusOMDS Mon­it­or­ing and Pro­tec­tion Sys­tem.

All Ad­vant­ages of the PreCurs­or

Detect In­stabil­it­ies earli­er

Detect flame in­stabil­it­ies be­fore amp­litudes grow and other pro­tec­tion sys­tems react.

Pre­vent Damages

React early, be­fore the ac­tu­al risk of dam­age and pre­vent shut downs and the need for re­pair.

Save Costs

Re­duce costs for main­ten­ance, re­pair and shut downs due to im­proved ma­chine re­li­ab­il­ity.
