Heat transfer in the boundary layer of a circulating fluidized bed boiler
Paper i proceeding, 1996

The heat transfer coefficient was measured with dark (steel) and light (silver) spherical probes, 5-15 mm in diameter, in a circulating fluidized bed boiler under various operating conditions. The probes were located ar different axial and radial positions in the wall region of the furnace, where fluid dynamic and thermal boundary layers are formed. A model is proposed to connect the measured heat transfer coefficient and its constituents with the local bed characteristics.
