摘要：

Analysis of solid deposits from the gas circuit of the pressurized fluid bed combustion (PFBC) plant in Escatron (N.E. Spain) showed them to be mainly composed of particles of anhydrite (CaSO4) with a mean diameter of 6 mu m, cemented by a partially devitrified glassy matrix comprising complex sulfates, including langbeinite, K2Mg2 (SO4)(3). Formation of these deposits is interpreted using phase diagrams for the systems CaSO4-MgSO4-K2SO4 and CaSO4-MgSO4-Na2SO4. Deposit compositions are located in the primary crystallization field of anhydrite, with first liquid formation below 690 degrees C. Copyright (C) 1996 Elsevier Science Ltd.
