A refining and/or petrochemical facility comprising at least one reactor or furnace configured to perform a process or processes related to oil refining and/or petrochemical industries at temperatures essentially equal to or exceeding about 500 degrees Celsius (° C.) and at least one rotary apparatus configured to generate a heated fluidic medium for inputting thermal energy into said at least one reactor or furnace, the at least one rotary apparatus comprises:
- a casing with at least one inlet and at least one exit,
- a rotor comprising at least one row of rotor blades arranged over a circumference of a rotor hub mounted onto a rotor shaft, and
- a plurality of stationary vanes arranged into an assembly at least upstream of the at least one row of rotor blades,
- wherein said at least one rotary apparatus is configured to receive an amount of input energy, the input energy comprising electrical energy, and
- wherein the at least one rotary apparatus is further configured to operate such that an amount of thermal energy is imparted to a stream of fluidic medium directed along a flow path formed inside the casing between the inlet and the exit by virtue of a series of energy transformations occurring when said stream of fluidic medium passes through the stationary guide vanes and the at least one row of the rotor blades, respectively, whereby a stream of heated fluidic medium is generated.
