Thermal power stations in containers


Gavardo proposes horizontal steam generators with internal coil, with 3 smoke passes and high efficiency (90%), free from qualified conductor (according to the new Ministerial Decree 94, 07/08/2020). The internal coils composed by two concentric coils are made of carbon steel tubes P235GH/P265GH/ASTM A106Gr.B.

The coil with the smaller diameter acts as combustion chamber and is closed with a cap in refractory material. The outer coil is used for the remaining smoke passes. All pressure parts, including the steam collector, are designed according to the PED Directive 2014/68/EU, and are complete with conformity certification. The special design of the steam collector favours the separation of the liquid component from steam.

The boiler body that is not in pressure is made of high thickness structural steel, while the base is made with boxed beams or UPN to improve the behaviour in case of thermal expansion. The insulation with rock wool reduces thermal inertia. The standard electrical panel, with IP55 protection, is in painted sheet steel and includes: main switch; auxiliary start selector; reset button for safety blocks; digital temperature controller for reading and continuous control of the steam temperature; warning lights signalling boiler failures.
