FIELD: heating and drying methods. SUBSTANCE: device is provided with pulse burner 12 for burning fuel and forming pulsating flow of combustion products and acoustic pressure wave. Pulse burner has combustion chamber 18 connected with at least one resonance pipe 20. Resonance chamber 14 surrounds at least part of pulse burner and is provided with injector 34 located below in way of flow relative to resonance pipe 20. Injector 34 is used for facilitating flow of combustion products and forming pulsating velocity head. In drying system 10, injector extends to drying chamber 16 where combustion products get in contact with flow being loaded. In heating system, injector 34 extends to ejector which mixes combustion products with return flow escaping from heat exchanger for forming the flow to heat exchanger. EFFECT: intensification of drying and heating processes. 12 cl, 4 dwg
