We investigated a nonlinear advection-diffusion-reaction equation for apassive scalar field. The purpose is to understand how the compressibility canaffect the front dynamics and the bulk burning rate. We study two classes offlows: periodic shear flow and cellular flow both in the case of fast advectionregime, analysing the system at varying the extent of compressibility and thereaction rate. We find that the bulk burning rate in a shear flow increaseswith compressibility intensity.  Furthermore, the faster the reaction the more important the difference withrespect to the laminar case. The effect has been quantitatively measured and itturns out to be generally little. For the cellular flow, the two extreme caseshave been investigated, with the whole perturbation situated either in thecentre of the vortex or in the periphery. The dependence in this case does notshow a monotonic scaling with different behaviour in the two cases. Theenhancing remains modest and always less than 20%
