    摘要: The invention is in the field of boiler control and relates to a control method for the operation of a combustion boiler, comprising providing a predetermined upper limit (V F,max ) for the flue gas velocity in at least one location of the boiler; monitoring the flue gas velocity (V F ) during the combustion of fuel in said at least one location of the boiler; comparing the flue gas velocity(V F ) with the predetermined upper limit (V F,max ); decreasing the thermal load of the boiler if the flue gas velocity exceeds the predetermined upper limit (V F,max ). The invention also relates to a control system configured to execute the control method.

    摘要: The invention relates to a method for starting up a fluidized bed boiler, such as a circulating fluidized bed (CFB) or a bubbling fluidized bed (BFB) boiler, for operation with a predetermined concentration of ilmenite particles in the bed material. The invention also relates to a method for pre-oxidizing ilmenite, to pre-oxidized ilmenite and to the use of pre-oxidized ilmenite in a fluidized bed boiler.
