A method of and apparatus for decreasing attack of detrimental components of solid particle suspensions on heat transfer surfaces in a heat transfer chamber in a fluidized bed reactor. The method includes introducing solid particles into a first chamber, which is a dilution chamber, on top of a bed of solid particles therein through a dilution chamber inlet disposed in an upper part of the dilution chamber, and discharging solid particles from the dilution chamber through an outlet disposed in a lower part of the dilution chamber, into a heat transfer chamber, and introducing a flushing gas into at least a portion of the dilution chamber for performing at least one of inactivating in and separating from the bed of solid particles in the dilution chamber, impurities detrimental to heat transfer surfaces in the heat transfer chamber.
