FIELD: power engineering, applicable at thermal power stations for masutless ignition of power-generating boiler from the cold state to the operating condition and bias lighting-up of coal-pulverizing flame. SUBSTANCE: the installation has device 3 for eddy of the flow of air mixture to different sides installed before muffled chamber 1 of fuel thermo- preparation. Device 3 consists of external (4) and internal (5) eddying chambers provided with guide vanes 6. EFFECT: enhanced time of stay of carbon particles in the thermo-preparation chamber. 2 dwg
