Abstract
1. Горелка с плазменным розжигом, содержащая, по меньшей мере, две ступени жаровых труб и плазмотрон для розжига угольной пыли в жаровой трубе первой ступени указанных, по меньшей мере, двух ступеней жаровых труб, в которой факел жаровой трубы предыдущей ступени предназначен для розжига угольной пыли в жаровой трубе следующей ступени или поддержания горения в подаваемом воздухе в жаровой трубе следующей ступени, отличающаяся тем, что осевое направление указанного плазмотрона параллельно направлению, вдоль которого поток пылевоздушной смеси поступает в жаровую трубу первой ступени, и параллельно оси жаровых труб. ! 2. Горелка по п.1, отличающаяся тем, что содержит отклоняющую трубу для направления потока пылевоздушной смеси в указанные, по меньшей мере, две ступени жаровых труб, в которой один конец отклоняющей трубы на стороне жаровых труб параллелен оси жаровых труб, при этом указанный плазмотрон выполнен с возможностью введения в жаровую трубу первой ступени через стенку указанной отклоняющей трубы вдоль осевого направления жаровых труб. ! 3. Горелка по п.2, отличающаяся тем, что содержит направляющую пластину, установленную вдоль оси отклоняющей трубы, причем один конец направляющей пластины на стороне жаровых труб параллелен оси плазмотрона. ! 4. Горелка по п.3, отличающаяся тем, что направляющая пластина продолжается до зоны входа жаровой трубы первой ступени. ! 5. Горелка по п.4, отличающаяся тем, что концы плазмотрона и направляющей пластины расположены на оси жаровых труб или отклонены от оси жаровых труб на заданное расстояние. ! 6. Горелка по любому из пп.3-5, отличающаяся тем, что направляющая пластина имеет1. A burner with plasma ignition, containing at least two stages of flame tubes and a plasma torch for ignition of coal dust in the flame tube of the first stage of the specified at least two stages of flame tubes, in which the flame of the flame tube of the previous stage is intended for ignition of coal dust in the flame tube of the next stage or maintaining combustion in the supplied air in the flame tube of the next stage, characterized in that the axial direction of the said plasmatron is parallel to the direction along which the flow of the dust-air mixture enters the flame tube of the first stage, and parallel to the axis of the flame tubes. ! 2. Burner according to claim 1, characterized in that it comprises a deflection pipe for directing the flow of the dust-air mixture into said at least two stages of flame tubes, in which one end of the deflection tube on the side of the flame tubes is parallel to the axis of the flame tubes, while said the plasmatron is configured to be inserted into the first stage flame tube through the wall of said deflecting tube along the axial direction of the flame tubes. ! 3. The burner according to claim 2, characterized in that it comprises a guide plate installed along the axis of the deflecting tube, and one end of the guide plate on the side of the flame tubes is parallel to the axis of the plasmatron. ! 4. Burner according to claim 3, characterized in that the guide plate extends up to the inlet zone of the first stage flame tube. ! 5. The burner according to claim 4, characterized in that the ends of the plasma torch and the guide plate are located on the axis of the flame tubes or deviated from the axis of the flame tubes at a predetermined distance. ! 6. Burner according to any one of claims 3-5, characterized in that the guide plate has
