HORIZONTAL COAL DECOMPOSITION DEVICE WITH MULTIPLE BURNERS

摘要

Disclosed is a horizontal coal decomposition device with multiple burners, which includes a sealed rotary kiln body (1) arranged horizontally. Multiple close-spaced burners (4), at one side of which multiple gas inlet pipes (5) and air inlet pipes (6) are arranged correspondingly, and at the other side of which multiple close-spaced heat radiating pipes (7) are arrange correspondingly, are arranged in the rotary kiln body (1). The space among the burners (4), gas inlet pipes (5), air inlet pipes (6) and the inner wall of the rotary kiln body (1) forms a propulsion and separation passage (9) for coal material. A collecting pipe (10) is arranged on the rotary kiln body (1) for collecting the fuel gas and tar gas decomposed from coal. The close-spaced heat radiating pipes (7) are communicated with a flame gas collecting pipe (12) which extends outside of the rotary kiln. Pulverized coal can be decomposed quickly and efficiently according to the invention, thereby improving the utilization coefficient of coal resources.
