METHOD AND DEVICE FOR MAINTAINING A CONSTANT TEMPERATURE IN A FLUIDIZED BURNING PLANT.

摘要

To maintain a constant regulating variable, particularly of the bed temperature of a fluidized-bed combustion plant, a regulating element (24) is used which is arranged in a feed line (20) for feeding fluidization air to a syphon (15), via which solid matter separated from the flue gas of the fluidized-bed combustion plant is fed back into the fluidized bed (5). The actuating drive (23) of the regulating element (24) is coupled to a temperature sensor (27) arranged in the fluidized bed (5), in such a manner that the quantity of fluidizing air is increased when the measured bed temperature exceeds a predetermined value. The quantity of fluidizing air is reduced when the measured bed temperature drops below the predetermined value. …IMAGE…
