Heat transfer characteristics between the horizontal tube and the fluidized-bed proper have been investigated in a bench-scale pressurized fluidized-bed combustor for the combustion of anthracite coal. Effects of fluidizing velocity(0.9, 1.1, 1.3 m/s), bed temperature(850, 900, 950 ℃) and amount of excess air(10, 20, 30%) on the individual heat transfer coefficient have been determined. The heat transfer coefficient has increased with increasing bed temperature, while it has decreased with increasing fluidizing gas velocity. The values of heat transfer coefficient in the pressured fluidized-bed combustor have been in the range of 370-720 W/m(2)K, which are much higher than those of typical value(200 W/m(2)K) in the atmospheric bubbling fluidized-bed combustor. The heat transfer coefficients have been well correlated in terms of operating parameters by way of dimensionless as well as dimensional forms.
