Company patents

Valmet Technologies Oy

Valmet Technologies Oy's patent strategy shows a surprising decline in several key manufacturing and materials categories, with a 100% year-over-year drop in patenting activity for Separation Processes (Filtration, Distillation) and Heat Exchangers (Specific Types) so far in 2026, despite a significant 66.7% growth in Material Handling (Sheets, Webs) patents in 2024. This suggests a notable shift away from previously active areas, even as Material Handling remains a focus, representing 13.3% of their portfolio.

Method for heating a heat exchange medium in a fluidized bed boiler, a fluidized bed boiler, and a loopseal heat exchanger

Filed:2021-11-02Pub:2025-12-30
Applicant:Valmet Technologies Oy

A method for heating a heat exchange medium in a fluidized bed boiler ( 100 ), the method comprising burning first fuel ( 165 ) in a first furnace ( 162 ) of the fluidized bed boiler ( 100 ) to produce first flue gas ( 163 ); recovering heat from the first flue gas ( 163 ) to a heat exchange medium using a first heat exchanger ( 310 ); conveying the heat exchange medium from the first heat exchanger ( 310 ) to a second heat exchanger ( 320 ), of which at least a part is arranged in contact with a fluidized bed of the fluidized bed boiler ( 100 ); burning second fuel ( 175 ) in a second furnace ( 172 ) of the fluidized bed boiler ( 100 ) to produce second flue gas ( 173 ); conveying the heat exchange medium from the second heat exchanger ( 320 ) to a third heat exchanger ( 330 ); and recovering heat from the second flue gas ( 173 ) to the heat exchange medium using the third heat exchanger ( 330 ). A fluidized bed boiler ( 100 ) for performing the method. A loopseal heat exchanger ( 400 ) that is, when installed in a loopseal of a circulating fluidized bed boiler, configured to burn second fuel ( 175 ) in a second furnace ( 172 ) of the loopseal heat exchanger ( 400 ) to produce second flue gas ( 173 ); convey the heat exchange medium from the second heat exchanger ( 320 ) to a third heat exchanger ( 330 ); and recover heat from the second flue gas ( 173 ) to the heat exchange medium using the third heat exchanger ( 330 ).
