Abstract
We present theoretical self--consistent models of Planetary Nebulae including detailed dust heating. Galactic, LMC and SMC abundance patterns are used in a comparison of dusty and dust free models. We show that dust has a strong effect on the thermal structure and emission line spectrum of highly ionised species in Planetary Nebulae.

These models have implications for excitation and energy balance methods for determining central star temperatures. We present results for [OIII] 5007 and [NII] 6583$lines for galactic, LMC and SMC abundances.
