Abstract

The invention provides an external burning and internal heating typed coal carbonization furnace, from top to bottom, comprising a preheating zone for preheating raw coals; and a drying zone for drying said raw coals and producing cold flue gas at the same time; and a carbonization zone for carbonizing the dried raw coals into carbonized products; and a cooling zone for cooling the carbonized products with said cold flue gas; and said cold flue gas produced from the drying zone are introduced into a cold flue gas pipe of said cooling zone. The furnace of the invention sufficiently not only utilizes the cold flue gas produced to cool the carbonized products, so as to enhance the carbonization efficiency, but also allows a great amount of sulphur to be removed from the flue gas in the cooling process, which makes the furnace of the invention energy saving and environmentally protective.
