Ultra-supercritical boilers use pressures in the 4,500 psi range. Typically these are used in coal-fired power plants where the whole idea of using such high pressures is to gain efficiency. The higher the pressure, the higher the efficiency. However, there are limits. Given the temperatures and pressures involved, the stress on the boiler is
