Steel Coal Silo Facilities for Misumi Power Station of The Chugoku Electric Power Co., Inc.

摘要

This coal silo replaced the conventional cylindrical concrete silo and it is the largest-scale multisquare-celled steel coal silo in the world. It was jointly developed by Chugoku Electric Power Co., Inc., and Mitsubishi Heavy Industries, Ltd., and delivered to the Misumi Power Station in June 1998. It features (1) reduced storage area, (2) a bent sag-shell panel wall that resists horizontal pressure of coal, (3) an improved field construction period due to well-managed blocks in the plant and (4) remote automatic coal discharging operation with variable blending ratio. This facility now operates satisfactorily and has received the customer's favorable view.
