Material characterization - a new route to cost-effective design of bulk handling plant for thermal power stations and associated facilities

摘要

The Bulk Handling Group of ALSTOM Automation Ltd at Whetstone, Leicester, specialises in coal, resultant ash & dust and limestone handling for thermal power stations and associated facilities. Specific characteristics for these bulk materials are reviewed and related to the necessary geometric parameters required to ensure good handleability in the plants designed. Power station projects in which the Group has been involved with over the last five years and those projected for the future are referred to as examples of how the materials characteristics have been considered and utilised in the design of cost efficient, highly reliable plants. A thorough knowledge of boiler operations is a prerequisite to achieving the optimum capabilities of the handling systems.
