Abstract
The utility model discloses an external heat radiation type dry distillation furnace for oil shale. A combustion chamber is added to a furnace body under the circumstance of not increasing the cost and is connected with a combustion gas pipe and a combustion-supporting air pipe; gas and air are combusted in the combustion chamber through a combustor; heat is transferred to the oil shale in a dry distillation chamber in a heat radiation way through a furnace wall of the combustion chamber, namely the heat for low-temperature dry distillation of the oil shale is provided by external heat radiation instead of an original gas heat carrier. Therefore, the stable temperature in the combustion chamber is guaranteed and the heat is fully utilized. The generated clean dry distillation gas is high-calorific-value dry distillation gas generated by low-temperature dry distillation of the shale, the quantity of furnace outlet gas generated by dry distillation of each ton of shale is about 40Nm<3>, and the volume ratio of H2 in the dry distillation gas is not less than 50%.
