QUICK-ACTING STEAM GENERATOR Russian patent published in 2004 - IPC

FIELD: steam generating equipment, particularly movable steam generators to utilize heat energy of non-transportable associated petroleum gas. SUBSTANCE: steam generator comprises cylindrical tubular furnace. Tubular furnace is composed of several spiral coil pipes, feedwater supplying and overheated water discharging manifold having economizer, heat insulating shield with combustion product extraction means and of vortex ejector arranged at furnace inlet. Vortex injector has gas tangential input, atmospheric air axial input having untwisting diffuser. Diffuser outlet is formed as ring-shaped burner having peripheral guide vane. EFFECT: maintaining of acceptable temperature level (not more than 1100 C) and protection of steam generator components against sulfur compounds action due to air inflow. 1 dwg
