The non-linear diffusion equation for the temperature in the fireball model with a high initial temperature in the central region is solved numerically. It is shown that the nonlinear solution has a much longer relaxation time for high initial temperature than the linearized one. The evaporation spectrum is calculated using the solved solution and is compared with the one by the equilibrium fireball model.
