Computational simulation of flow, heat transfer and combustion in a vertical tube heat recovery system generator (HRSG) with a single angel roof, a dual angle roof and an air flow optimized evase are studied. Existing theoretical models for flow and gas combustion [1] are used to predict how the three kinds of roof shapes influence the flue gas and temperature distribution in the whole HRSG Sys...

The low frequency noise from heat recovery steam generator (HRSG) makes dominant contribution to the noise on the boundary of plant, which generation mechanism is investigated in this presentation. The non-stationary flow field and aeroacoustic noise is studied with hybrid numerical simulation, which is comprised of CFD method based on Large Eddy Simulation (LES) and acoustic analogy by using F...

Optimal revamping, sizing, and operation of an existing gas-turbine combined-cycle dual-purpose power/desalination plant – simultaneous electricity freshwater generation which operates with a heat recovery steam one-pressure level (1P-HRSG) multi-stage flash desalination process, is addressed. The sizes configurations the gas turbine unit are kept same as in through study. However, 1P-HRSG conv...

Background and Introduction In 2003 ETD held a successful International Conference and Workshop on HRSG Technology at which the importance of repair and maintenance technologies was recognised as a major factor in the successful and economic plant operation. As a relatively new, and rapidly evolving, technology HRSGs have had a history of faults, particularly in early models, which were not des...

Most of the advanced integrated energy systems need a heat recovery steam cycle (HRSC), either fired or unfired, that recovers the waste heat from gas turbines and process units in order to generate electric power and supply mechanical power to compressors, heat to endothermic processes, and steam to external users. The key feature of such HRSCs is the integration between the heat recovery stea...
