While the spiral wound furnace (SWUP) meets today's market needs for variable pressure operation, B&W is continuing the research and development of advanced supercritical boiler designs, including a vertical tube universal pressure boiler (VTUP).

The ideal furnace design would have vertical tubes and be capable of variable pressure operation over the load range while exhibiting natural circulation flow characteristics (flow increasing as heat absorption increases), thus protecting the tubes from overheating.

The supercritical steam cycle provides an improvement in heat rate (efficiency) as compared to the subcritical steam cycle. Additional gains in efficiency are possible as the cycle temperature and pressure are further increased.

Research continues in tube materials to develop higher efficiency boiler and turbine systems.
