Gas Fuel Control
Lub qhuav qis NOx II (DLN-2) tswj qhov system tswj kev faib cov roj roj rau ntau qhov kev sib txuas ntawm lub tshuab hluav taws xob. Cov roj ntws tawm mus rau txhua qhov sib dhos roj nozzle yog qhov ua haujlwm ntawm kev siv hluav taws xob kub (TTRF1) thiab IGV kub tswj hom. Los ntawm kev sib xyaw ua ke ntawm cov roj hluav taws xob thiab kev hloov pauv ntawm cov qauv sib txuas los ntawm kev sib kis ntawm qhov hluav taws xob los ntawm kev sib xyaw ua ntej ntawm cov khoom siv siab dua, cov pa roj carbon monoxide tsawg (NOx) tau ua tiav.
Roj roj yog tswj los ntawm cov pa nres / ceev piv valve (SRV), thawj, theem nrab thiab quaternary gas tswj li qub (GCV), thiab premix splitter valve (PMSV). Lub premix splitter valve tswj qhov sib cais ntawm theem nrab thiab theem nrab roj ntws.Txhua li qub yog servo tswj los ntawm cov teeb liab los ntawm SPEEDTRONIC tswj vaj huam sib luag.
Nws yog cov roj tswj valve uas tswj cov roj uas xav tau hauv kev teb rau cov lus txib FSR. Txhawm rau ua kom nws ua qhov no raws li kev kwv yees tau, qhov ceev piv valve yog tsim los tswj lub siab ua ntej (P2) ntawm qhov nkag ntawm cov roj tswj valve raws li kev ua haujlwm ntawm roj turbine ceev.
Muaj peb lub ntsiab DLN-2 combustion hom: Thawj, Lean-Lean, thiab Premix.
Thawj hom muaj nyob ntawm lub teeb tawm mus rau 81% kho nrawm, roj ntws mus rau thawj lub taub hau nkaus xwb. Lean-Lean yog los ntawm 81% kho qhov nrawm mus rau qhov ntsuas kub ntawm kev sib txuas ua ntej, nrog roj rau cov thawj thiab qib thib ob. Hauv kev ua haujlwm Premix roj yog qhia rau theem nrab, tertiary thiab quaternary nozzles. Qhov tsawg kawg nkaus load rau lub lag luam no yog teem los ntawm combustion reference kub thiab IGV txoj hauj lwm.
Roj Tswj Valves
Txoj hauj lwm ntawm cov roj tswj valve ntsaws yog npaj kom muaj feem rau FSR2 uas sawv cev hu ua-rau roj ntws. Kev ua haujlwm ntawm lub caij nplooj ntoos hlav-loaded roj tswj valve yog los ntawm lub tog raj kheej hydraulic tswj los ntawm electro-hydraulic servovalve.
Thaum lub turbine yuav tsum khiav ntawm cov roj roj qhov kev tso cai L4, L20FGX thiab L2TVX (turbine purge tiav) yuav tsum yog 'muaj tseeb', zoo ib yam li cov kua system.Qhov no tso cai rau lub Gas Control Valve qhib. Lub stroke ntawm lub valve yuav proportional rau FSR.
FSR mus los ntawm cov roj splitter (yuav tsum tau tham nyob rau hauv dual roj seem) qhov twg cov roj yuav tsum tau ua FSR2, uas yog conditioned rau offset thiab nce. Cov teeb liab no, FSROUT, mus rau VSVO daim npav qhov twg nws hloov mus rau lub teeb liab analog thiab tom qab ntawd tso tawm mus rau lub servo valve los ntawm TSVO daim npav. Cov pa tswj valve qia txoj hauj lwm yog paub los ntawm cov zis ntawm ib tug linear variable sib txawv transformer (LVDT) thiab pub rov qab los ntawm TSVO daim card mus rau ib tug ua hauj lwm amplifier ntawm daim card VSVO qhov twg nws muab piv rau FSROUT input teeb liab ntawm ib tug summing junction. Muaj ob lub LVDTs muab kev tawm tswv yim; ob ntawm peb tus tswj hwm tau mob siab rau ib qho LVDT txhua, thaum lub thib peb xaiv cov lus pom zoo tshaj plaws los ntawm lub rooj vag siab-xaiv diode. Yog tias qhov kev tawm tswv yim tsis raug nrog FSROUT, lub tshuab ua haujlwm ntawm VSVO daim npav yuav hloov lub teeb liab mus rau hydraulic servovalve kom tsav lub roj tswj valve hauv kev taw qhia kom txo qhov yuam kev. Nyob rau hauv txoj kev no qhov kev sib raug zoo ntawm txoj hauj lwm thiab FSR2 yog tswj thiab tswj valve kom raug ntsuas cov roj roj.
