Abstract
Coal is first fed into the oven chamber through a plurality of first filling openings until the bases of the resultant cone-shaped charges are approximately in contact. Thereafter, coal is fed into a plurality of second filling openings positioned between adjacent first filling openings. The above operations are repeated until the oven chamber is filled. The coarser coal is thus distributed in a plurality of diagonal layers in the oven chamber. Filling gas is removed from the oven chamber during feeding through filling openings which are not being employed for feeding.
