Ib daim ntawv raj feem ntau yog ua los ntawm ib daim phaj tiaj tiaj, daim ntawv nrog cov qhov drilled kom txais cov raj lossis cov kav dej hauv qhov chaw raug thiab cov qauv piv rau ib leeg. Cov ntawv raj yog siv los txhawb thiab cais cov raj hauv cov cua sov thiab boilers lossis los txhawb cov ntsiab lus lim. Cov raj yog txuas rau daim ntawv raj los ntawm hydraulic siab lossis los ntawm kev nthuav dav ntawm cov menyuam. Ib daim ntawv raj yuav raug them nrog cov khoom siv cladding uas ua haujlwm ua ib qho kev thaiv xeb thiab insulator. Cov ntawv raj carbon qis tuaj yeem suav nrog ib txheej ntawm cov hlau alloy siab dua uas txuas rau qhov chaw kom muab kev tiv thaiv xeb zoo dua yam tsis muaj tus nqi ntawm kev siv cov khoom siv khov kho, uas txhais tau tias nws tuaj yeem txuag tau ntau tus nqi.
Tej zaum qhov kev siv cov ntawv raj zoo tshaj plaws yog ua cov khoom txhawb nqa hauv cov khoom siv hloov pauv cua sov thiab cov boilers. Cov khoom siv no muaj cov raj nyias nyias uas nyob hauv lub plhaub kaw. Cov raj tau txhawb nqa ntawm ob qho kawg los ntawm cov ntawv uas tau drilled hauv tus qauv ua ntej kom cov raj kawg hla dhau daim ntawv. Qhov kawg ntawm cov raj uas nkag mus rau hauv daim ntawv raj tau nthuav dav kom xauv lawv rau hauv qhov chaw thiab tsim ib lub foob. Tus qauv qhov raj lossis "pitch" hloov qhov deb ntawm ib lub raj mus rau lwm qhov thiab lub kaum sab xis ntawm cov raj piv rau ib leeg thiab rau qhov kev taw qhia ntawm kev ntws. Qhov no tso cai rau kev tswj hwm ntawm cov kua dej velocities thiab siab poob, thiab muab qhov siab tshaj plaws ntawm turbulance thiab lub raj nto kev sib cuag rau kev hloov pauv cua sov zoo.
