ROTATING FURNACE CHAIN CURTAIN Russian patent published in 2022 - IPC F27B7/18 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to a chain curtain of rotating furnaces of wet and semi-dry, combined production method. The chain curtain of a rotating furnace contains a section of chains, the attachment points of which to the furnace body are arranged in the form of a multi-pass helix, and an additional section of chains located in the loading zone of the furnace and containing chains having two ends. With their first end, the chains are attached to a non-rotating structure fixed in the end part of the furnace. The remaining ends of the chains of the additional section of the chains are connected to the additional chain in such a way that the additional chain is located at a distance of no more than 10 mm from the inner surface of the furnace.

EFFECT: reliability of the rotating furnace operation is improved by reducing the number of unplanned equipment shutdowns, reducing the specific gas consumption for firing the charge and improving the quality of the finished fired product produced due to the increased productivity of the rotating furnace.
