Nozzle pipeline structure for gunpowder fuel gas starting

The utility model belongs to an engine starting technology, and relates to a nozzle pipeline structure for the gunpowder fuel gas starting of an engine. The nozzle pipeline structure for the gunpowder fuel gas starting comprises mounting seats, fan-shaped ring pipes, end caps, tapered nozzle orifices and gas inlet nozzles, wherein the mounting seats are welded on a turbine casing, and except the mounting seat connected with an external pipeline, inlets of the other mounting seats are sealed by the end caps; the mounting seats are connected into an annular gunpowder fuel gas pipeline through the fan-shaped ring pipes; the tapered nozzles orifices are formed in an outer ring between blade passages of a turbine guider; the gas inlet nozzles are arranged in the mounting seats; an annular passage on the turbine casing is communicated with the tapered nozzle orifices in guider through gas flow passages in the gas inlet nozzles. According to the nozzle pipeline structure, a special starting turbine is not required,
