Abstract

Tokom posljednjih sto godina pritisak pare i temperature u termoenergetskim postrojenjima stalno su podizani s ciljem poboljšanja stepena iskorištenja. Osnovni zahtjevi pri izgradnji novih postrojenja su povećanje stepena iskorištenja i što manja proizvodnja CO₂. Većina čelika koji su ugrađeni u postojećim podkritičnim postrojenjima su prevaziđeni. U kotlovima koji se revitaliziraju pojedini čelici se više ne ugrađuju, a ugrađuju se novije vrste čelika. U novim kotlovima taj trend zamjene materijala je još više izražen, jer se nova termoenergetska postrojenja prave s mnogo većim stepenom iskorištenja, većim instalisanim snagama i rade s većim parametrima pritiska i temperature. Današnja nadkritična postrojenja s temperaturom pare 600 °C na termoelektranama koja rade s promjenjivim opterećenjem već su napravljena, a cilj budućih postrojenja su radne temperature 630 °C do 650 °C. Međutim, temperature 600 °C do 630 °C moguće je koristiti za trenutne tipove postrojenja, na temelju već razvijenih materijala koji uključuju 9-12 %Cr martenzitne (P91, P92, P911, VM12) i austenitne čelike. Ovim radom je predstavljen pregled razvoja toplootpornih čelika u dvadesetom vijeku, naročito tokom posljednjih nekoliko desetljeća.
