  • Flow Stability of Heat Recovery Steam Generators | J. Eng

    Mar 01, 2004 · This paper presents the results of theoretical flow stability analyses of two different types of natural circulation heat recovery steam generators (HRSG)—a two-drum steam generator—and a HRSG with a horizontal tube bank. The investigation shows the influence of the boiler geometry on the flow stability of the steam generators.Learn More

  • T&HE: LESSON - 27 STEAM BOILERS/GENERATORS, …

    Natural draft boilers: In this the draft is produced by natural circulation of air and gas.In effect the chimney, boiler and the outer air constitute a large U-tube as shown in Fig 27.3. The column of gases in the chimney is one vertical limb; the other limb is a column of cold outside air and the lower horizontal portion of the U-tube represents the boiler.Learn More

  • Modeling and simulation of a natural circulation water

    Oct 15, 2019 · A detailed model of a natural circulation water-tube boiler unit is developed using RELAP5/MOD3.2 including all the main components (steam generator, drum, heat exchangers, pipeline of steam and feedwater, and regulation and control system). The steam boiler model was developed from documented plant design, performance data reference and staff Learn More

  • Heat Recovery Steam Generators of Binary Combined-Cycle

    Jun 16, 2021 · In a horizontal gas flow HRSG, steam is generated in heated vertical tubes with natural circulation of the fluid, as in drum-type power boilers. Fig. 6. P …Learn More
