DEVICE AND SYSTEM FOR CONTROLLING THE TEMPERATURE IN A FLUIDIZED BED BOILER

摘要

The invention concerns an arrangement and a system for the determination of the temperature in a combustion boiler (1) with fluidised bed (10). At least one thermoelectric element (25) is integrated with the air nozzle (4) in the form of a rod-shaped body that is fixed arranged at its first end to the air nozzle and that extends vertically upwards into the bed from the air nozzle with thermoelectric element arranged at a distance from the air nozzle. It is possible in this manner to obtain a measurement arrangement and system for the detection of the temperature of the bed that is less exposed to the eroding environment in the fluidised bed.
