FIELD: power engineering. SUBSTANCE: method comes to filling service container with powder like material above minimum level and emptying it down to minimum level. Minimum level is determined basing on condition to preclude fluidizing of gas through fill level of powder-like material in service container. Pulse delivery of gas into powder like medium along entire length of transportation pipeline is additionally provided. Gas pulse pressure is chosen basing on condition to exclude fluidization of gas in pulse delivered through summary layer of powder-like material in transportation pipeline and material fill level in service container. EFFECT: reduced consumption of gas and increased reliability. 1 dwg
