Water Handbook - Boiler System Failures | SUEZ

Straight tube, shell-and-tube waste heat boilers frequently develop tube and tube sheet failures due to the imposition of unequal stresses. A primary cause of this is the uneven distribution of hot gases across the face of the tube sheet. The tubes involved tend to come loose, creating leakage problems.

Straight-Tube Boiler: The 1st water-tube boiler was the straight-tube boiler, in which straight tubes, 3 to 4 in OD, inclined at about 15 and staggered with 7 to 8 in spacing, connected two vertical headers. One header was a downcomer, or downtake, which is supplied nearly saturated water to the tubes. The water partially boiled in the tubes.

Hydrogen Boiler - Corner Tube Boiler, Gas Steam Boiler

Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be …

Water for the Boiler | Spirax Sarco

Water-tube boilers tend to be higher rated, perhaps over 1 000 tonnes/h of steam. This means that even a small percentage blowdown can represent a high mass to be blown down. Water-tube boilers tend to operate at higher pressures, usually up to 150 bar g. The higher the pressure, the greater the energy contained in the blowdown water.

Fire tube or "fire in tube" boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. (Refer Figure 2.2). Fire tube boilers, typically have a lower initial cost, are more fuel efficient and easier to operate, but they are limited generally to capacities of 25 tons/hr and pressures of 17.5 kg/cm 2.

Boiler Water Wall Panels are a series of tubes welded together tangentially or with membrane bar between them to form the walls of the boilers combustion chamber. Typically two side walls, a rear wall, a front wall, a floor and the roof section. These tubes contain mostly water in liquid form that slowly evaporates and rises in the boiler during combustion.
