Preheater for Anthracite Carbonization in Rotary Furnaces

Abstract

Coke production is carried out by coal carbonization. The most frequently used coal is anthracite, which features a very low content of volatile substances that not exceed 7%. Current anthracite production is carried out in rotary furnaces, consists of processes as follows: drying, heating, pyrolysis and calcination. Coke cooling is performed in cooling device located at the end of the furnace. To enhance the performance and reduce the specific heat consumption, use of the preheating device for rotary charge was proposed. The charge granulometry allows using the preheating device based on thin layer principle. Proposed solution was verified by simulations.
