Abstract
The present study is investigated quantitatively on the heat transfer characteristics of a horizontal circular pipe in the pressurized fluidized bed. Small scale model of fluidized bed is worked in a pressurized gas, then, the horizontal circular pipe in the fluidized bed was heated electrically. Experiments were carried out for the parameters of bed pressure, bed height and air flow rate. Characteristics of Heat transfer are obtained by measuring the electric power, the heated surface temperature and the bed bulk temperature around the horizontal circular pipe. Relationship between the heat transfer and the flow characteristics were deeply discussed.
