Abstract :
Mitsubishi Heavy Industries Ltd. (MHI), the world largest power plant manufacturer, has been leading the development of technologies to meet the requirements special to the Japanese utility power industry. Mitsubishi supplied a number of supercritical sliding pressure units for firing fuels such as oil, gas and coal, with successful operating performance. In this paper, design features of a supercritical sliding pressure operation boiler are reported, considering points for a dual fuel firing boiler, low NOx firing technologies and the experience of oil and gas-firing supercritical sliding pressure operation boiler represented by the ultrasupercritical pressure gas firing units with a steam condition of 31 MPa (316 kgf/cm2 g), 566/566/566°C
