In this paper, we consider a semilinear heat equation with Dirichlet boundary equation in a bounded domain. Under some assumptions, we show that the solution of the above problem quenches in a finite time and its quenching time goes to that of the solution of a certain differential equation when the size of the domain tends to infinity. Finally, we give some numerical experiments to illustrate our analysis.
