### available second moment of area - Boiler and Pressure

We see that the moment of inertia is greater in (a) than (b). This is because the axis of rotation is closer to the center of mass of the system in (b). The simple analogy is that of a rod. The moment of inertia about one end is, but the moment of inertia through the center of mass along its length is .

Sep 27, 2020 · Compared with large inertia in boiler, the inertia in turbine section is usually small. At least, it can be ignored from the actual operation data of this plant. Based on this model, the unit load and main steam pressure can be simply predicted; more important, this model can be a potential platform to employ the stochastic model predictive

Oct 12, 2011 · A Boiler drum consists of a cylindrical portion long, Also the Moment of inertia = the mass the radius of gyration squared. which: and The inner radius = Thus the corrected value of the Mean Radius is . Substituting this back in the original equation for the Moment of Inertia This value can now be used to correct the original guess.
