ABSTRACT:
A method for operating a coal dust furnace comprises blowing into the furnace a mixture of combustion air and combustion coal dust having a specified range of grain sizes, the range of grain sizes having an upper limiting grain size, and, for reducing the temperature of the flame, also blowing into the furnace additional temperature reducing coal dust, the range of grain sizes of the additional coal dust lying essentially above the specified upper limiting grain size, this temperature reducing coal dust subsequently being burnt in additional areas of the furnace. The two types of coal dust are blown into the furnace in concentric streams each surrounded by an annular stream of its associated combustion air. If the combustion coal dust is the central stream, then its combustion air is fed in a swirling stream.
