Libaka tsa mantlha tsa ts'ebeliso li kenyelletsa:

Tlhahiso ea Matla a Thermal a Bohlokoa ka ho Fetisisa: P92 ke thepa ea mantlha bakeng sa liphaephe tse kholo tsa mouoane le ho futhumatsa liphaephe tsa mouoane hape ka har'a li-unit tsa 1000MW tse bohlokoa ka ho fetisisa, ka mocheso o phahameng ka ho fetisisa oa moralo oa ts'ebetso oa 625°C. Ho 600°C, khatello e lumelletsoeng ea moralo e fihla ho 128MPa, le matla a ho thekesela a mocheso o phahameng≥100MPa. Matla a yona a ho phatloha ha ho kgephoha ha mocheso o phahameng a ka ba 30% ho feta P91, mme yuniti e le nngwe ya kilowatt e ja ditone tse fihlang ho 800.

Likarolo tsa Bohlokoa tsa Boiler: Li sebelisoa haholo ho li-header tsa boiler, li-superheater, li-reheater le likarolo tse ling tsa khatello. Ke e 'ngoe ea lihlopha tsa tšepe tse ratoang bakeng sa tlhahiso e kholo ea lisebelisoa tsa lifeme tsa motlakase tsa mocheso ka hare ho naha le machabeng.

Indasteri ea Petrochemical: E sebelisoa liphaepheng tsa reactor ea hydrogenation, liphaepheng tsa ontong tse petsohang, le litsamaisong tse ling tsa mocheso o phahameng le khatello e phahameng.

Matla a Nyutlelie: A boetse a sebelisoa litsamaisong tsa liphaephe tsa lehlakore la bobeli tsa lifeme tsa matla a nyutlelie tsa moloko oa boraro tse kang AP1000.

Ha e bapisoa le litšepe tse sa hloekang tsa austenitic, P92 e fana ka melemo e kenyeletsang ho hanyetsa ho matla ha mafome, ho khanna ha mocheso o phahameng, le coefficient e tlase ea katoloso ea mocheso.
