In the paper, the chemical reactions during the producing process of calcium carbide in different structures and parts of calcium carbide furnace is analyzed. The mass transportation model and the thermochemistry measurement model in the producing process are constructed. Combined with the actual production of calcium carbide, the energy situation in the producing process of calcium carbide is simulated. Simulation results show the fundamental energy requirement in the producing process of calcium carbide is 2716 kWh. The temperature of the charging stock surface and the temperature of the furnace gas have great impacts on the energy consumption of the calcium carbide production. With the temperature of the furnace gas increases 1℃, the electricity consumption will increase 0.25 kWh/t.
