We consider steady compressible Navier-Stokes-Fourier system in a bounded two-dimensional domain. We show the existence of a weak solution for arbitrarily large data for the pressure law $p(\varrho ,\vartheta )\sim {\varrho }^{\gamma }+\varrho \vartheta$ if $\gamma >1$ and $p(\varrho ,\vartheta )\sim \varrho {ln}^{\alpha }(1+\varrho )+\varrho \vartheta$ if $\gamma =1$, $\alpha >0$, depending on the model for the heat flux.
