We model farinfrared (FIR) spectra of radioweak quasars with the assumption that the emission is from heated dust, and that the heating is due to the central engine via energetic particles. These energetic particles are diffusing from a postulated source near the central engine through a tenuous galactic halo to arrive at the dust which is taken to be in molecular clouds in a disk configuration. This picture does not depend on a particular geometry of the disk such as warps. This concept can readily reproduce the range of observed mm/submm/FIR/IR spectra.
