A problem of the production of the glasses lens is to balance production time and a high quality. In the factory, it produces lenses as follows. The raw materials of the liquid state are heated in a furnace. A chemical reaction is caused in liquid and solidifies. It is thought that a natural 'convection in the liquid influences the quality of the lens. In this study, we performed the numerical analysis of the natural convection with internal heat generation by the chemical reaction. We calculated convection, temperature and the concentration of reactant by the FDM. A natural convection was generated by temperature distribution in the system, and the distribution of the reactant concentration changed. We changed the value of the non-dimensional numbers and examined the maximum velocity in the liquid and the end time for chemical reaction to find a condition of the lens production.
