In this letter, we propose a lattice Boltzmann (LB) model for reactive flow simulations at the low-Mach-number regime, which is suitable to accommodate significant density variation. A recently proposed model for compressible thermal flows on standard lattices is herein extended to combustion applications, where species equations are properly described in order to account for compressibility effects. This fundamental extension allows to apply LB approach to a wide range of combustion phenomena, which were not properly addressed so far. The effectiveness of the proposed approach is proved by simulating combustion of hydrogen/air mixtures in a mesoscale channel, and a validation against reference numerical solution in the continuum limit is presented.
