FIELD: oil-and-gas industry.SUBSTANCE: set of inventions relates to development of deposits with the help of steam. Downhole gas generator comprises burner head assembly with casing having the channel extending there through and expansion zone crossing said channel. Expansion zone comprises one or several fuel feed stages to feed fuel into combustion chamber. Note here that said fuel feed stage features ID larger than ID of said channel. Fire tube assembly is connected with burner head assembly downstream of said casing. Fire tube assembly has casing with one or several fluid channels extending through said casing, combustion chamber composed by the casing inner surface, fluid feed system communicated with combustion chamber.EFFECT: fire stabilisation zone, control over flame shape, more complete combustion of fluids, controlled emission.44 cl, 1 tbl, 49 dwg |
