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 The absorption refrigeration cycle is a basic cycle that establishes the systems for utilizing mid-low temperature heat sources. A new thermal compressor model with a key parameter of boost pressure ratio is proposed to optimize the absorption-generation process. The ultimate generation pressure and boost pressure ratio are used to represent

Geometric and Thermodynamic Optimization of a Heat Recovery Steam Generator: A Constructal Design
Journal of Heat Transfer, 2012Heat recovery steam generator (HRSG) is a critically important subsystem of a combined cycle. The global objective of a HRSG is to heat the stream of water. The HRSG is composed of three major sections, including an economizer, an evaporator, and a superheater. In this study, a water tube HRSG is considered and its main design features are deduced from

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 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.

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.
