Appendix A: Tables

Table A.1:   The other Galactic Bulge PNe observed with Spitzer/IRS (program $\char93 $3633).

Table A.2:   The rest of PNe (non-Galactic Bulge) observed within Spitzer/IRS program $\char93 $3633.

Appendix B: Spectra

\end{figure} Figure B.1:

Spitzer/IRS spectra of Galactic Bulge PNe, which show dual-dust chemistry (see Table 1). The spectral type is shown under name of PN. Note the simultaneous detection of PAH emission features in the 6-14 $\mu $m range (dashed vertical lines at 6.2, ``7.7'', 8.6 and 11.3 $\mu $m - right panels) together with crystalline silicate features (dashed vertical lines at 23.5, 27.5 and 33.8 $\mu $m - left panels).

Spitzer/IRS spectra of Galactic Bulge PNe, which show dual-dust chemistry cont. (see Table 1). The spectral type is shown under name of PN; none - means neither [WC] nor wels. Note the simultaneous detection of PAH emission features in the 6-14 $\mu $m range (dashed vertical lines at 6.2, ``7.7'', 8.6 and 11.3 $\mu $m - right panels) together with crystalline silicate features (dashed vertical lines at 23.5, 27.5 and 33.8 $\mu $m - left panels).

Spitzer/IRS spectra of Galactic Bulge PNe, which show dual-dust chemistry cont. (see Table 1). The spectral type is shown under name of PN; none - means neither [WC] nor wels. Note the simultaneous detection of PAH emission features in the 6-14 $\mu $m range (dashed vertical lines at 6.2, ``7.7'', 8.6 and 11.3 $\mu $m - right panels) together with crystalline silicate features (dashed vertical lines at 23.5, 27.5 and 33.8 $\mu $m - left panels).

\end{figure} Figure B.4:

Spitzer/IRS spectra of Galactic Bulge PNe, which do not show dual-dust chemistry (see Table A.1). The spectral type is shown under name of PN; none - means neither [WC] nor wels. Dashed vertical lines at 23.5, 27.5 and 33.8 $\mu $m on the left panels mark position of crystalline silicate bands, while those at 6.2, ``7.7'', 8.6 and 11.3 $\mu $m on the right panels show position of PAH features.

Spitzer/IRS spectra of PNe, which are classified here as non-Galactic Bulge sources (see Table A.2). The spectral type is shown under name of PN. Dashed vertical lines at 23.5, 27.5 and 33.8 $\mu $m on the left panels mark position of crystalline silicate bands, while those at 6.2, ``7.7'', 8.6 and 11.3 $\mu $m on the right panels show position of PAH features.
