A reactor and method for the conversion of hydrocarbon gases utilizes a reactor (12, 312, 412, 512, 612, 712) having a unique feed assembly with an original vortex combustion chamber (40, 340, 436, 536, 636, 736), a diverging conduit (48, 348, 448, 548, 648, 748), and a cylindrical reactor chamber (40, 340, 436, 536, 636, 736). This design creates a compact combustion zone and an inwardly swirling fluid flow pattern of the feed gases to form a swirling gas mixture that passes through a diverging conduit (48, 348, 448, 548, 648, 748). The feed streams can be introduced into the reactor at any angle (perpendicular, axial, or something between, or a combination of the above forms) with swirling flow components. This provides conditions suitable for efficient cracking of hydrocarbons, such as ethane, to form olefins.

Combined burner for blowing oxidizing gas and fuel into melting furnace, which is fixedly installed into the furnace and provided with outlet apertures for fuel and oxidizing gas, consists, according to this invention, of fixed part (2) of the burner (1) and of a movable nozzle (4), which is rotatably installed inside the body (2.1) of the fixed part (2) of the burner, supply (7) of the oxidizing gas is connected to the movable nozzle (4) and it is controlled by actuator (3), installed outside of the working space of the furnace, while the axis x2 of the orifice of the movable nozzle (4) is diverted from the rotation axis x1 of the movable nozzle (4) by angle a in the range of 5-60° and the movable nozzle (4) is rotatable around the axis X1 in any direction by angle β in the range of 0-180°. The movable nozzle allows directing blown gases into various places in the furnace. At the same time, the whole burner is fixedly installed in the wall or ceiling, or the cover of the furnace, and the space of the furnace thus remains sealed.
