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.
