Method and apparatus for manufacturing cement using rotary generated thermal energy

A cement production facility comprising at least one rotary apparatus configured to generate a heated fluidic medium and at least one heat-consuming unit configured to carry out a process or processes related to cement production, the at least one rotary apparatus comprising:

• 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 the at least one rotary apparatus is 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 vanes and the at least one row of rotor blades, respectively, whereby a stream of heated fluidic medium is generated, and
• wherein said at least one rotary apparatus is configured to receive an amount of input energy, the input energy comprising electrical energy, and to generate a heated fluidic medium for inputting thermal energy into at least one heat-consuming unit configured to carry out a process or processes related to cement production at temperatures essentially equal to or exceeding about 500 degrees Celsius (° C.).

A method for inputting thermal energy into a process or processes related to producing cement in a cement production facility, the method comprises generation of a heated fluidic medium by at least one rotary apparatus integrated into the cement production facility, the at least one rotary apparatus comprising:

• 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,
• the method further comprises:
• integrating the at least one rotary apparatus into the cement production facility configured to carry out process or processes related to production of cement at temperatures essentially equal to or exceeding about 500 degrees Celsius (° C.),
• conducting an amount of input energy into the at least one rotary apparatus integrated into the cement production facility, the input energy comprising electrical energy, and
• operating the at least one rotary apparatus integrated into the cement production facility 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 vanes and the at least one row of rotor blades, respectively, whereby a stream of heated fluidic medium is generated.
