METHOD OF AND APPARATUS FOR DECREASING ATTACK OF DETRIMENTAL COMPONENTS OF SOLID PARTICLE SUSPENSIONS ON HEAT TRANSFER SURFACES

摘要

A method of and an apparatus for decreasing attack of detrimental components of solid particle suspensions on heat transfer surfaces in heat transfer chambers in fluidized bed reactors. According to the invention there is provided a dilution chamber (16), with a bed of solid particles (16') circulating in the system therein. The dilution chamber is disposed in the particle flow upstream of the heat transfer chamber (18) for inactivating impurities, detrimental to heat transfer surfaces (46), in said solid particle flow and/or for separating impurities therefrom. Solid particles are discharged from the reactor chamber into the heat transfer chamber via the dilution chamber, for cleaning the solid flow from detrimental components.
