  • Method and a device for preheating a fluidized bed
    Patent number: 5347936
    Abstract: A method and a device for preheating a particulate fluidized bed which is supplied with air for fluidization of bed material and for combustion of main fuel through gas paths that include fluidization members for injection and distribution of the air over the fluidized bed. The bed material is preheated to the ignition temperature for the main fuel used in the fluidized bed by members arranged in the gas paths for combustion of starting fuel. These members are designed and arranged so that the air is supplied to the fluidized bed along the same path through gas paths and fluidization members upon preheating with starting fuel as upon combustion of main fuel in the fluidized bed. The members for combustion of starting fuel are arranged in the fluidization members and comprise fuel injectors, fuel pipes, ignition members and control members.
