The invention discloses a fixed type self-bearing superheated steam generator in a compound cycle mode. The fixed type self-bearing superheated steam generator in the compound cycle mode comprises a smoke system and a water path system. The smoke system comprises a burner, a radiation hearth, a transitional connection flue, a superheater, an economizer and a chimney which are sequentially communicated in the movement direction of hot smoke. The water path system comprises a boiler fed water inlet, a steam outlet and a pipeline. The smoke system further comprises a double-drum horizontal heat exchanger. The superheater is located below the economizer. The double-drum horizontal heat exchanger is located below the superheater. A double-drum transversely arranged tube bundle is located inside the double-drum horizontal heat exchanger. The effect of injecting superheated steam into an oil layer is good, the recovery efficiency of crude oil is increased, and the heat energy utilization rate is greatly improved. The fixed type self-bearing superheated steam generator in the compound cycle mode is needed to solve the technical problem of high water content of steam.
Description
technical field [0001] The invention relates to a superheated steam generator in a fixed self-supporting composite cycle mode. Background technique [0002] At present, ordinary steam generators produced at home and abroad usually produce wet steam, and the dryness of the steam is controlled within 80% to avoid fouling on the inner wall of the boiler tube and affect safe operation. With the high-efficiency development of heavy oil and the continuous deepening of high-cycle production in the later stage, the water in the steam will not only not help the production, but will increase the volume of the formation pores, increase the water content of the produced fluid, and reduce the production of heavy oil . In order to effectively reduce boiler operating costs, implement the national policy of energy conservation, consumption reduction and emission reduction, and meet the higher requirements of thermal recovery equipment for new oil recovery technology at home and abroad, a f...
