摘要： Is provided a method for starting up a pressurized fluidized bed incinerator system by which cracking of silica sand as a bed material can be prevented at low costs. By heating the silica sand as the bed material filled up in a bottom portion of a pressurized fluidized bed incinerator, a temperature of a freeboard of the incinerator is heated, and after the temperature of the freeboard is heated to 750 to 900° C., a material to be treated having a water-containing organic substance is fed to the pressurized fluidized bed incinerator.

摘要： The present invention concerns a CLC method and plant for a hydrocarbon feedstock, comprising combustion of said hydrocarbon feedstock (8) on contact with an oxygen carrier in form of particles in a reduction zone (R0), and oxidation of the oxygen carrier from reduction zone (R0) on contact with an oxidizing gas, preferably air, in an oxidation zone. According to the invention, gaseous oxygen is released by the oxygen carrier in a sealing device (S1) operating in a dual fluidized bed and positioned in the path of said carrier from the oxidation zone to the combustion zone, and it is mixed with part of the combustion fumes intended to be recycled to the reduction zone. The gaseous oxygen then enables combustion of the residual unburned species that may be contained in the combustion fumes and/or it participates in the combustion of the hydrocarbon feedstock in the reduction zone.
