Design Features and Trial Operation of Tsuruga No.2 700MW Coal-Fired Boiler

摘要

The 700 MW coal-fired supercritical sliding pressure boiler at Hokuriku Electric Power Co., Inc., Tsuruga Thermal Power Station No.2 was designed based on the high-performance, reliable No.1 500 MW boiler. Applying elevated steam of 593/593 deg C, MHI's state-of-the-art low-NOx combustion A-PM burner, A-MACT and MRS pulverizer technology, this boiler has achieved the highest combustion performance with extremely low NOx emission and unburned carbon together with outstanding boiler operation. This paper reports the design features and operation results of the boiler, e.g., (1) extremely low NOx and unburned carbon due to cutting-edge combustion and (2) superior boiler operating performance and minimum 15percent load in exclusive cod firing.
