NOVELTY - Coal gas production device with solar calcined material comprises a split calcining device, electrolytic water-oxygen generating device, and coal gas generator (1). The coal gas generator is provided with gasification agent inlet, coal powder inlet, a gas outlet and a slag outlet. The outdoor unit for split calcining device comprises a feeding device, a preheating chamber (4a, 4b), calcining chamber and cooling chamber and a discharging device, where the material inlet and material outlet of each chamber is provided with a material lock (3) e.g. between the preheating chamber.    USE - Used as a coal gas production device with solar calcined material.    ADVANTAGE - The device can save non-renewable energy and avoid discharge of greenhouse gas; and can save the production cost.    DETAILED DESCRIPTION - Coal gas production device with solar calcined material comprises a split calcining device, electrolytic water-oxygen generating device, and coal gas generator (1). The coal gas generator is provided with gasification agent inlet, coal powder inlet, a gas outlet and a slag outlet. The outdoor unit for split calcining device comprises a feeding device, a preheating chamber (4a, 4b), calcining chamber and cooling chamber and a discharging device, where the material inlet and material outlet of each chamber is provided with a material lock (3) between the preheating chamber, preheating chamber and calcining chamber, and calcining chamber and cooling chamber. The cooling chamber is connected with a material conveying device (5). The pre-heating chamber is connected with a feeding device. The cooling chamber is connected with the discharging device. The device is further provided with a gas heating chamber, which is provided with solar energy composite optical heating system. The calcining chamber is a solar calcining chamber, and a gas pipe connecting mode is as follows: the oxygen storage tank of electrolytic water-oxygen generating device is connected to the circulating fan, where the outlet of the fan is connected to the cooling chamber air inlet, which is connected to the cooling chamber air outlet; the cooling chamber is connected with the air inlet pipe of the heating chamber; the gas outlet pipe in wall surface constituting the heating chamber is connected to the solar calcining chamber gas inlet and the solar calcining chamber gas outlet divided into two paths, where in the one path, a gasification agent inlet is connected to the coal gas generator, and in other path it is connected with the pre-heating chamber; and the air outlet of the pre-heating chamber is connected to the circulating fan.
