TECHNOLOGICAL HEATER, PRIMARILY, FOR STABILIZATION OF NATURAL GAS IN GASEOUS STATE Russian patent published in 2007 - IPC F22B7/00 F28D15/00 

FIELD: pipeline transportation, possible use for heating liquid oil products, gaseous and liquid substances, contact of which with fire and hot products of combustion is undesirable.

SUBSTANCE: technological heater, primarily for stabilization of natural gas in gaseous state consists of pressurized vessel, filled with liquid intermediate heat carrier. Tubular convection heat exchange connected to main pipeline is installed in upper part of the pressurized vessel horizontally above the surface of liquid intermediate heat carrier. Steam generator, composed of flue tubes and immersed in intermediate liquid heat carrier, is positioned under tubular convection heat exchange. Inside each flue tube a turbulence promoter for gaseous products of combustion is installed. Upper ends of flue tubes are connected to smoke stack, and their lower ends are welded into the bottom of the pressurized vessel and connected to combustion chamber, wherein a burner device is positioned, which is connected to air supercharger by a forcing air duct. Pressurized vessel is connected to auxiliary vessel of normalizer of steam pressure of intermediate heat carrier, which auxiliary vessel comprises a stabilizing heat exchange and breathing pipe interconnected by lower ends. The upper end of stabilizing tubular heat exchange is connected by pressure control pipeline to upper part of main vessel. Auxiliary vessel is connected to lower part of pressurized vessel by return pipeline.

EFFECT: improved energy characteristics, reduced dimensions and metal cost of heater.
