Feasibility research on redundancy removal and derating of coal handling systems in large and medium coalfired power plants

Abstract

Abstract:

At present, the working hours of coalfired units are declining, and there is great redundancy in the output of coal handling systems. Based on the status quo and expectation for power generation market, it analyzed the operational reliability and output of the coal handling systems and proposed feasible redundancy removal schemes.Under the premise of dualconfiguration for coal handling systems, it is feasible to cut the redundant ouput. It is recommended to reduce the output of the coal system and optimize the system configuration in new or rebuilt projects.
