ABSTRACT:
A method for starting up a partial combustion process, using a burner, wherein finely divided carbon-containing fuel is supplied to a reactor or gasifier and an oxygen-containing gas is supplied separately from the said fuel to the reactor or gasifier and is mixed with the said fuel adjacent the outlet of the burner in the reactor or gasifier. During a predetermined period a low rank particulate carbon-containing fuel is supplied to the reactor prior to the start of the partial combustion process, said low rank fuel spontaneously reacting with oxygen when brought into contact with the said oxygen-containing gas and subsequently switching the burner to a less reactive finedly divided carbon-containing fuel.
