| description | The invention relates to a combined type coal water slurry nozzle provided with an ignition device. The combined type coal water slurry nozzle provided with the ignition device comprises an outer sprayer, a middle sprayer, an inner sprayer and a center pipe which are coaxially arranged, wherein an ignition cable is arranged on the outer wall of the center pipe, a hydrocyclone which can form rotary jet is arranged at the front end of the center pipe, an axial through hole is formed in the hydrocyclone, certain shrinkage is formed at the front end of the center pipe relative to the front end of the through hole of the hydrocyclone, part of or all the circumferential edge of the hydrocyclone is contacted with the inner cavity wall of the front end of the inner sprayer; certain retraction is formed in the front end face of the hydrocyclone relative to the end face reference surface of the inner sprayer, so that a premixing cavity B is formed. The combined type coal water slurry nozzle provided with the ignition d |
