Abstract:
    The invention relates to a process and reactor for converting coal of high moisture content and ash content to synthesis gas. The gasification reactor is provided with a plurality of burner openings which are arranged in the reactor at two levels. The burners at the lower level point downwards and are operated at a high oxygen/carbon ratio, in order to keep the slag orifice clear. The burners at the higher level are operated at a low oxygen/carbon ratio, in order to maintain the correct oxygen/carbon ratio for effective overall conversion and low gas outlet temperatures.
