Research and Application of Double-Reheat Boiler in China

The ultra-supercritical (USC) double-reheat technology is an immediate area of research focus in China, since the thermal efficiency USC unit higher than single-reheat unit. parameters and capacity China have made major breakthroughs, units are as high 47–48%, which highest world. boiler one most important devices for unit, design concept precision a vital effect on operation power station. difficult factors layout heating surface steam temperature regulation method. Therefore, this work summarizes arrangement method existing China. It hoped that will set benchmark development future 700 °C generation
