A BIT MORE
1. Terumah is only Batel in 100 parts Chulin. Since the Terumah Teme'ah is not Batel it may not be eaten and it may also not be used for fuel for a fire because of the concern that if it is kept around it may end up being eaten.
DAVAR SHE'YESH LO MATIRIN
Konamos are regarded as a Davar she'Yesh Lo Matirin because it is a Mitzvah to be released from your Neder; however it is not a Mitzvah to be released from your Neder making something into Terumah. The Ran explains that since it is a Mitzvah to be released from your Neder it is as if you have already been released. However regarding Terumah since it is not a Mitzvah to be released from your Neder and the Heter does not happen by itself it is not regarded as if your Neder has already been released.
ASKING FOR RELEASE
If wine that one prohibited on himself gets mixed in with other wine, even if only one drop of the prohibited wine falls into an entire barrel of wine, the whole barrel is forbidden because a person should get released from his Neder and thus it is similar to a Davar she'Yesh Lo Matirin that is not Batel if it gets mixed in with the same Min. (Shulchan Aruch YD 216:10)
