Steam raising system on skid or in container
25 January 2013
Steam systems from Babcock Wanson can be supplied as skid mounted packages or as containerised plant rooms to meet new steam demand or to supplement an existing need. Easy and quick to install, the factory assembled
Easy and quick to install, the factory assembled and tested unit is supplied with full CE certification in accordance with the Pressure Equipment Directive and is ready to use as soon as it is installed on site.
The company can provide a solution for low and high pressure steam duties using its range of traditional Steambloc firetube boilers or coil type steam generator technology.Most packages include water treatment equipment and can incorporate features such as fully automatic start/stop, TDS control and remote monitoring to keep site operational costs to the minimum.
The steam plant can often be assembled within a modified shipping container; outputs from 150 to 2000kg/h can be accommodated in an ISO standard 20ft container, or up to 6000kg/h in the 40ft size. As standard, containers have ventilation louvers, lighting and anti-frost heating, plus any special lifting/stacking/paint finish. A short flue section can be provided for immediate use; for longer term operation a chimney complying with Local Authority requirements can be supplied.
Where a skid mounted plant room is specified and headroom on site is limited, a low level or floor-mounted feedwater tank can be provided with a simple booster pump to provide the required head to the main boiler feed system. This ensures feedwater can be operated at the optimum temperature to drive off dissolved oxygen, which helps reduce water treatment chemical consumption.
Vertical or horizontal coil type steam generators are popular for these assemblies. In normal operation they respond rapidly to any change of steam load or can provide a full head of steam in minutes from a cold start.
