Abstract (en)

[origin: EP0898115A1] The boiler uses a dense fluidised bed in a furnace drum (1). Hot particles fluidised by gas leave the bed at the top of this drum and pass through a horizontal pipe (12) to a second, smaller, drum (2). The solid particles are separated from the gas in this drum. The gas is taken off (20) from the top of the second drum. The solid particles pass from the bottom of the drum into a pipe (23) leading to a heat-exchanger (3). The particles flow past a coil (3A) carrying fluid, especially water and return (31) to the bottom of the furnace drum. The water enters (39) the heat exchanger at the bottom and exits (30) at the top and passes through a second heat exchanger (3B) inside the furnace.
