Header in boiler
WebThe header should be sized so that the pressure loss at full flow is small. All secondary circuit flows and the flow from the boilers should normally be at the top, or one end of the header. All secondary circuit returns and the return to the boilers should be at the bottom, or other end of the header. Web1.1 The geometry of the headers The geometry of the headers is given in fig. 2. It shows the basic form without its fixation on the building structures. The header collects the steam from 40 tubes in four rows. The right end has an end plate with an inspection tube attached, whereas the steam leaves by the left end past a temperature

WebBlowdown control. Boiler blowdown is the removal of water from a boiler. Its purpose is to control boiler water parameters within prescribed limits to minimize scale, corrosion, carryover, and other specific problems. Blowdown is also used to remove suspended solids present in the system. WebThe pre-heated water then enters the boiler at the economizer inlet header. The piping system carrying the water to the economizer inlet header is called the feedwater piping system. (Note: The temperatures shown in …
WebA technical analysis revealed that more than 90 small condensate branch lines fed into the main return header, and the combined estimated flow from those lines required a flow capability equivalent of at least 14 2-in. lines. Unfortunately, a 3-in. header has an internal volume that is only 2.24 times that of a 2-in. pipe.
