Abstract
Process and apparatus for control of the heat transfer between a circulating bed of solid particles and a heat exchanger (6) located inside a fluidization enclosure (1) supplied with solid particles and connected to a device for recovering (4) and recycling (5) the particles into the fluidized bed. The heat exchange coefficient of the exchanger (6) is adapted at each moment to the heat transfer requirements of the plant by varying in the same sense the concentration of solid particles in the circulating bed, by increasing or reducing the quantity of circulating particles to increase or reduce, respectively, the exchange coefficient to the value required by the demand. The invention is particularly applicable to steam production boilers operating on coal.
