In this paper, we consider the numerical solution of the flame front equation,
which is one of the most fundamental equations for modeling combustion theory.
A schema combining a finite difference approach in the time direction and a spectral
method for the space discretization is proposed. We give a detailed analysis for the
proposed schema by providing some stability and error estimates in a particular case.
For the general case, although we are unable to provide a rigorous proof for the stability,
some numerical experiments are carried out to verify the efficiency of the schema.
Our numerical results show that the stable solution manifolds have a simple structure
when $\beta$ is small, while they become more complex as the bifurcation parameter $\beta$ increases. At last numerical experiments were performed to support the claim the
solution of flame front equation preserves the same structure as K-S equation.
