Maachi Boiler System
This page gives 3 illustrations of Boilers the subject of Modularisation Studies, only one was successful. All of the Boilers were suitable for Modularisation but the advantages were in 2 cases not sufficient.
This 1st Example is a corner tube boiler from Maachi for supply to the Sage Project Gas Plant. The outline Diagram gives an indication of physical size. The boiler capacity was for 30 te/hr of steam. The approximate weight was of the order of 300 te. In the diagram there are 3 basis, initially the idea was for just one base, module. The problem that prevented this approach was an existing bridge, the wheel foot print of the trailer was acceptable but the gross loading was to high. The other figure is the fuel system for the boiler. The fuel source was noxious gases from the plant trimmed with fuel gas. Combustion is often a suitable way to produce steam and at the same time modify the noxious gas to acceptable condition.
This 2nd Example is a corner tube boiler from KTI for a Refinery Project at Mongstad . The outline panorama diagram gives an indication of physical size. The boiler capacity was for 100 te/hr of steam. The approximate weight was of the order of 850 te +. Iike the first examplebesides raising steam its purpose was to deal with CO2 from the Reactor Column upstream. Post stream are correction sections to the flue gas exhaust. The sequence of Diagrams shows design studies, fabrication in Italy export by Sea to Norway and offloading and installing at site. In this instance all the access route accepted this large structure.
This 3rd Example is are boilers for a Refinery India. The outline plot shows the arrangement of the Utility Area and the Boilers system diagram their capabilty. Each of these Boilers could produce 200 or 400 te/hr of steam and the structures would be approximately 2 or 4 times the scale of the Mongstad Boiler. Besides Boiler size, the flue ducting arrangement at Mongstad was  volumous and such large objects factored are again not outstanding subjects for Modularisation. The other factor that applies to Paradip is that adjacent to the refinery was a large local labour capability for onsite fabrication and the need for manufacture in an area of expertease as was the case for Mongstad was not essential, for these reasons the  modularisation study concluded that Modularisation of the Boilers was not desireable
