ABSTRACT:
Green coal is charred in pre- and post- treatment carbonizers, then crushed, mixed with pitch, briquetted, tempered in a tempering oven, recirculated with succeeding green coal to char in a reducing atmosphere through only the latter part of the pre-treatment carbonizer and through the post-treatment carbonizer, cooled, and separated from the as yet unbriquetted char. The pre-treatment carbonization is characterized by having air updrafted through all the airbox zones under the travelling grate.
