Heating and Cooling | Inspect boiler drums effectively

The last and probably the most important inspection in the drum head is a visual examination of the head-to-shell attachment welds. This examination requires that any standing water and debris be removed and the circumferential weld area including the heat affected zone (HAZ) be cleaned on the lower half of the boiler drum (Figure 2).. After cleaning, inspect this weld area closely for

boiler drum manufacturing process

Likewise, reducing the boiler firing rate reduces the void fraction and water flows downward from the drum into the riser tube, reducing the level of the drum. This effect is known as shrink. If the steam flow out of the boiler increases, the drum pressure will drop and the boiling rate will increase, increasing the void fraction in the tubes

Boiler Replacement: Custom or Off the Shelf - Rentech Boilers

Typically the components, including the steam drum and boiler, are prefabricated in the shop and shipped to the site. But because of the large steam capacity of the Corpus Christi boiler, coupled with Valero's interest in a conservative design, it is too large to ship in one piece so a modular design was used.

Boiler circulation systems: natural circulation and forced

For both, steam drum systems as well as once-through steam generators (OTSG) systems, we must have uninterrupted flow of water through the tubes in order for the system to continuously generate steam. For an OTSG system, water travels only one time (single pass) through the boiler tubes before being converted to steam and sent to the steam turbine generator set for producing electricity.

3 Types of Circulation In Boiler - Water Treatment Basics

Separated steam from steam drum is sent to the turbine. The value of circulation ratio varies from 6 to 30 in industrial boilers. Circulation ratio for utility high pressure boilers is between 6 to 9.Circulation ratio is higher side as the density difference between steam & water is high.
