Mathematical modelling and design of an advanced once-through heat recovery steam generator
The once-through heat recovery steam generator design is ideally matched to very high temperature and pressure, well into the supercritical range. Moreover this type of boiler is structurally simpler than a conventional one, since no drum is required. A specific mathematical model has been developed. Thermodynamic model has been implemented to suit very high pressure (up to 240 bar), suband sup...
متن کاملMulti-objective optimization of heat recovery steam generators
In this paper, a multi-objective method is used to optimize a heat recovery steam generator (HRSG). Two objective functions have been used in the optimization, which are irreversibility and HRSG equivalent volume. The former expresses the exergetic efficiency and the latter demonstrates the cost of the HRSG. Decision variables are geometric and operational parameters of the HRSG. The result...

متن کاملFull-scale CFD Simulation and Measurement in a Heat Recovery Steam Generator
Flue gas generated by the wastewater incineration entrains a large number of ash particles which are composed of alkali substances into the heat recovery steam generator (HRSG). The deposition of particles rich in alkali on the tube surface of heat transfer can reduce the heat transfer efficiency; even cause severe capacitylimiting plugging and unscheduled shutdown. In the present work, a full-...
متن کاملNumerical and Experimental Study on Mechanism of Low Frequency Noise from Heat Recovery Steam Generator
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...
