Numerical calculation based on mass and energy balance of waste incineration in the fixed bed reactor

Abstract

To evaluate the waste process incineration, a mass, and energy balance is employed to investigate the waste incineration process in a fixed bed. Thermodynamics equilibrium is implemented to describe the incineration process. The complete combustion is only products CO2, H2O, SO2, ash, and excess O2 considered. The mass balance calculates the total mass flow in and out incinerator. Energy balance includes input heat, evaporating heat, chemical heat, radiation, and convection. The input heat is calculated by considering the heat capacity, temperature, heating value, and total mass flow. Evaporation heat is calculated based on the water content, mass flow of each aqueous, and evaporation hot water flow. The result shows that efficiency energy of waste incinerator up to 79,33%. It means the incinerator is included in the good category.
