The Boiler House – beta.spiraxsarco.com

For any one boiler, if the heat transfer rate (q_dot – body text.jpg) is increased, the maximum allowable boiler pressure is reduced. A compromise is reached with a furnace tube wall thickness of between 18 mm and 20 mm. This translates to a practical pressure limit for shell boilers of around 27 bar.
