Boiler Feedwater

2015-11-3 · Calculations 416 This last equation is a very good equation to have, because by simply knowing the steaming rate and cycles, one can calculate feedwater. Usually, this last equation is taken a step further to include percent blowdown instead of just cycles. Percent blowdown is defined as: Rearranging this equation reveals:

Water boils under constant temperature and pressure, so a horizontal line inside the enclosed region represents a vaporization process in the T-s diagram. The steam/water heating process in the boiler represented by the diagram in figure 2 can also be drawn in a T-s diagram (figure 4), if the boiler pressure is assumed to be e.g. 10 MPa.
