  We consider an energy conserving linear dynamics that we perturb by a Glauber
dynamics with random site dependent intensity. We prove hydrodynamic limits for
this non-reversible system in random media. The diffusion coefficient turns out
to depend on the random field only by its statistics. The diffusion coefficient
defined through the Green-Kubo formula is also studied and its convergence to
some homogenized diffusion coefficient is proved.
