Abstract (en)

[origin: EP1447622A2] To fire a high power flue boiler, with a coal fuel dust, a high proportion of the fuel is burned in a pre-combustion chamber (1) with a supply of combustion air (L), and the emerging gas flame (6) is accelerated by at least 80% by a jet (2) to be blown into the boiler flue (7) . The gas flame is blown into the boiler flue coaxially, or at an angle of 8-14[deg] against the flue axis selected to ensure that the upper mantle line of the flame is parallel to the flue mantle line.
