The boiler is capable of providing the required steam for ONE
turbine.
(customer to ensure broom-clean dismantling)
Maximum operating pressure: 44 bar(g)
Maximum operating temperature: 450°C
Fuel heat capacity (natural gas): 36 MW (round about 40 t/h steam)
The two burners and the associated control system were replaced in
2016.
The weight of the boiler can be estimated based on the dimensional
drawings. Dismantling and reassembly would be extremely complex, as
the boiler would need to be cut apart and welded back together
on-site. It cannot be transported in one piece.
