Lower Pressure Operation of Boiler than Design

The problem is mainly the specific volume of steam; reduction in pressure increases the specific volume. This leads to higher steam pipe and tube velocities thus increasing the pressure drop by a square function. Due to increase in superheated steam pressure drop at lower operating pressure and higher steam flow the changes in drum pressure
