The invention relates to the technical field of boiler soot blower equipment, and discloses a nozzle and a soot blower. The nozzle comprises a hollow main body (10), the hollow main body is provided with a blow medium inlet (102), a first nozzle (104) and a second nozzle (106) are arranged in sequence on the side wall of the hollow main body in the hollow main body extension direction, the center line of the first nozzle and the center line of the second nozzle are tilted by different angles relative to the cross section of the hollow main body (10), so that the jet flows of the first nozzle (104) and the second nozzle (106) are crossed. In the technical scheme, the first nozzle and the second nozzle are arranged on the hollow main body, and the center line of the first nozzle and the center line of the second nozzle are tilted by different angles relative to the cross section of the hollow main body, the first nozzle and the second nozzle form a crossing of jet flows, so that the maximum jet shear force on a water wall tube by the jet flows is reduced, and the jet area is enlarged.
