Abstract
The use of a heat exchanger pipe (300) in the fluidized bed of a fluidized bed boiler. The heat exchanger pipe (300) has a first dimension (dmax) in its crosssectional plane and a second dimension (dmin) in a direction transverse to the first dimension, the first dimension being greater than the second dimension. At least part of the heat exchanger pipe (300) is placed in a fluidized bed (100, 136, 133, 139, 130, 145) in such a way that the longitudinal direction of the pipe is at an angle smaller than 60 degrees to the horizontal plane. Said second dimension (dmin) is horizontal. The cross-section of the heat exchanger pipe (300) tapers towards the upper and lower edges. Furthermore, a fluidized bed boiler is presented for implementing said use. Moreover, a method is presented for heating a heat transfer fluid by a granular solid substance. In the method, a fluidized bed is formed of said solid substance in the fluidized bed boiler, and the heat exchanger pipe is used in the described manner.
