Boiler Technology - an overview | ScienceDirect Topics

All OT boilers incorporate relatively small bore evaporator tubes (~ 25 mm), which are generally arranged in a spiral/vertical fashion to form the furnace envelope. As the water is evaporated to high quality in an OT boiler, it is important to guard against dryout occurring in high heat flux zones or to take other precautions against the phenomenon associated with burnout.

With the boiler pressure at a minimum of 75% of the safety valve set pressure, the safety valve try lever is lifted to wide open position. Steam is discharged for 5 sec to 10 sec. The try lever is released, and the disk should snap to the closed position against the valve seat. Malfunctioning safety valves must be replaced as soon as possible.

are water-tube boiler with a boiler section that consists of closely-spaced water tubes covering the furnace wall. The waterwall boiler design allows much lighter, less expensive walls by having the waterwalls form an integral part of the boiler wall so that the wall is water cooled. If so equipped, the superheater and reheater

Spiral Pipe - an overview | ScienceDirect Topics

The uniform fluid temperature profile in the spiral water-cooled wall can be achieved in the full range of the loads of the boiler, with no need for a flow adjusting device at the furnace inlet. The spiral pipe water-cooled wall is currently widely used in ultra-supercritical boilers, particularly those operating at sliding pressures ( Shen and Chen, 2004 ).
