Abstract
A method of operating a fluidized bed reactor system for reacting fuel. The method includes introducing solid material particles, fluidization medium and fuel into a reactor chamber to provide a fluidized bed therewithin, reacting the fuel material within the fluidized bed to produce exhaust gas and discharging the exhaust gas from a reactor chamber outlet, introducing the exhaust gas into a particle separator and separating solid particles from the gas in the particle separator, discharging from the particle separator gas through a gas outlet and a first flow of separated solid particles through a solid particle outlet, and cooling, in a gas cooler, the gas discharged from the separator. A second flow of solid particles is branched off from the first flow of solid particles, before or after discharging the first flow of solid particles from the particle separator. The second flow of solid particles is introduced into the gas discharge from the separator at least before the cooling step, so that the solid particles mechanically dislodge deposits from, and thereby clean, the cooling surfaces in the gas cooler.
