Design and operation of 1,000 MW coal fired boiler

In June 1990, a 1,000 MW coal fired boiler, the largest capacity of its sort in Japan as well as Danes and Desex systems went into commercial operation after the commissioning trial operation at No. 1 Unit of Matsuura Thermal Power Station of the Electric Power Development Co., Ltd. The plant was constructed with an eye to stabilizing power supplies for the use of extensive areas and facilitating the diversification of energy resources, by utilizing, as its staple fuel, different kinds of imported coals with a variety of mineral characteristics. It is now satisfactorily operating with the most up-to-date technology introduced not only to enhance the system's reliability, efficiency, and operability but also to strengthen the environmental protection-- oriented capability. This paper introduces the design concept and trial operation performance of NOx control technologies in which the most advanced environmental control technologies have been integrated
