Abstract

A method of heating of bed material in a PFBC plant including a combustor and wherein bed level adjustment due to a load change is accomplished by injecting bed material into or discharging it from the combustor through feeding devices, the method including the steps of arranging two storage vessels, each adapted for injecting the bed material therefrom into the combustor and for storing bed material discharged from the combustor, and heating and maintaining the bed material in the storage vessels at the temperature corresponding to the bed temperature while maintaining the bed level of the combustor constant, by discharging bed material with the temperature of the bed from the combustor via the feeding device adapted for discharge of bed material, into one of the storage vessels with a predetermined feed speed and at the same time and at the same feed speed injecting bed material from the second storage vessel into the combustor via the feeding device adapted for injection of bed material.
