Closed feed water heater. Above diagram shows closed feed water heater and T-S curve. Feed water enters to the heater at point 2 and it is heated from T 2 to T 3 / by the condensation of bled steam from 6 to 3. The condensed steam at the intermediate pressure is required to be pumped back into the feed line to state 4 at the boiler pressure before being mixed with the feed water at 3 /.

The Feed water enters the boiler through the economizer tubes provided in the path of the flue gas. The feed water is heated in the economizer and then enters the boiler drum situated outside the furnace at the top of the Boiler. As air velocity is gradually increased, a stage is reached when the individual particle are suspended in the air

2018-10-4 · Figure 11 shows the effect of inlet water velocity on the removal of sulfate ion by the resin. It showed that varying the inlet velocity of raw water (4.0 to 6.0 m/min) resulted in decreased in the amount of sulfate ion concentration. A model for an industrial ion exchange facility for demineralization of boiler feed water has been

Boiler feed water quality is limited owing to problems of (1) scaling, (2) corrosion, and (3) foaming. In order to avoid these problems, the quality guidelines shown in Table IV have been adopted. Data in Table IV show a major difference between cooling water and boiler feed water quality constraints, in that boiler feed water has a strong relationship between water quality and the pressure of
