US6336429B1 - Drumless natural circulation boiler

A drumless natural circulation boiler system has a furnace enclosure with wall tubes and upper and lower headers connected to respective upper and lower ends of the wall tubes. At least one tangential steam/water separator is connected to a plurality of riser tubes that are also connected to the upper headers. The riser tubes return a steam/water mixture to the separator.

Applications Of Laser Profilometry For Boiler Tub

2006-8-15 · Figure 3, illustrates a split in the boiler tube wall due to freezing. A key advantage of using laser profilometry for the location and measurement of internal pitting is the fact that a 40' long boiler tube can be scanned very quickly (normally in less than two or three minutes) to obtain detailed, dimensional information without the negative

ONCE-THROUGH BOILERS - thermopedia.c

An alternative solution is to use rifled-bore tubing which, by creating centrifugal forces, causes more of the liquid phase to remain in contact with the tube wall, thus delaying dryout to higher qualities and/or enabling lower water velocities to be adopted.
