PURPOSE:To make a starting operation in a fluidized-bed furnace easy, by mixing to coexist catalyst particles which are effective to promote combustion of fuel with fluidized medium particles. CONSTITUTION:Combustion catalyst particles to lower the temperature to ignit fuel are mixed with fluidized medium particles. Following can be used as catalyst contents: metallic catalyst contents such as Pt, Pd; metallic mixture catalyst contents such as Pt+Pd, Pt+Rh; catalyst contents of oxide or mixture of those oxides such as Co, Cu, Mn, Cr, Ni, Fe; mixed catalyst contents of metal and oxide such as Pt+Co3O4, Pt+ThO2.CoO2; complex oxide catalyst contents such as LaCoO3, LaMnO3, CuCrO4, CoAl2O4. A catalyst consists of a carrier such as gamma-Al2O3, ZrO2, TiO2 carrying the above-mentioned catalyst contents. With such an arrangement, a starting operation can easily be performed in the titled furnace. |
