The original B&W boiler for supercritical applications was the Universal Pressure (UP®) boiler.
Designed for both supercritical and subcritical applications, this design is now used for supercritical applications; the drum boiler is used for subcritical applications.
The supercritical application is usually applied to systems with a capacity of 300 MW or larger due to steam turbine considerations.
The original UP boiler design dates back to the mid-1950s when B&W provided the 125 MW advanced supercritical boiler for American Electric Power's Philo station. This pioneering boiler/turbine system, with advanced steam conditions of 4500 psi/1150F/1050F/1000F (31 MPa/621C/566C/538C), was the world's first supercritical system.
The boiler design rapidly evolved to units as large as 1300 MW in the late 1960s. These boilers, nine of which are in operation, are among the largest capacity fossil fuel boilers in the world.
