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.
