Thermodynamic Optimization of Dual Pressure Heat Recovery Power Generation in Cement Production
2012 Asia-Pacific Power and Energy Engineering Conference, 2012The optimization goal for a waste heat revovery power generation system is to obtain maximum power output per ton clinker without increasing the heat rate of the cement production. The genetic algorithm theory was utilized to abtain the optimal match of thermodynamic parameters.

Abstract A general formula for the overall efficiency of a system in terms of the efficiencies of its components is used to optimize the flowsheet of an absorption heat pump. We demonstrate that the exergetic efficiency diagram ηe, i vs load (the portion of exergy input λi) gives a general approach for treating any process.

Optimal thermodynamic and economic volume of a heat recovery steam generator by constructal design
International Communications in Heat and Mass Transfer, 2012Abstract The ratios of gas flow to steam flow are huge in heat recovery steam generators (HRSGs) compared to other steam generators. So the volume which is occupied by components of the HRSG such as economizer, evaporator and superheater is important factor when the HRSG is applied in structures including buildings and ships.

Abstract In recent years, biomass gasification has emerged as a viable option for decentralized power generation, especially in developing countries. Another potential use of producer gas from biomass gasification is in terms of feedstock for Fischer–Tropsch (FT) synthesis – a process for manufacture of synthetic gasoline and diesel.

Abstract A new integrated energy plant is suggested and studied in the current research, aiming at enhancing the exergetic efficiency and minimizing the total product cost of a waste-to-energy (WTE) plant. For the integration, the condenser of the WTE plant is substituted with a thermoelectric generator.

Abstract Multi-objective genetic algorithms are used to optimize the structure, assignment of configuration and load resistance of a two-stage thermoelectric generator, where Skutterudite and Bi2Te3 are chosen as upper stage and lower stage TE leg materials, respectively. Heat convection and radiation are considered on the top of the upper substrate.
