Abstract The present invention features that of the four vertical pipes, the coal powder drying pipe and the heating pipe are connected serially to constitute one independent coal powder heaitng waste gas circulating system, and the first stage preheating pipe and and the second preheating pipe are connected serially to constitute another independent coal powder heating waste gas circulating system. Compared with single coal powder heating waste gas circulating process, the double coal powder heating waste gas circulating process has less waste gas exhaust to produce pollution, small system resistance and less engineering investment.
