Cogeneration System

A thermodynamic study of an indirect fired air turbine cogeneration system for the production of electricity and process steam has been made. Performance data showing the effect of compressor compression ratio and turbine inlet temperature on fuel utilization efficiency (first law efficiency), electrical to thermal energy ratio (power to heat ratio) and second law efficiency (exergetic efficiency) have been generated. Although fuel utilization efficiency and electrical to thermal energy ratio data do provide some useful information, it is the second law efficiency that provides the optimal design conditions. The performance data contained in this study should be useful to the decision-makers in the selection of optimal parameters at the system design stage of an indirect fired air turbine cogeneration system.

A previous study of an indirect fired air turbine cogeneration system has been extended to include the concept of reheat. The effects of the number of reheat stages and cycle pressure drops on system performance parameters (such as power and process heat production, fuel utilization efficiency, and second-law efficiency) are examined.

Cogeneration System

A previous study of an indirect fired air turbine cogeneration system has been extended to include the concept of regeneration. The effect of regenerator effectiveness and full regeneration as well as partial regeneration on system performance parameters (such as fuel utilization efficiency, power-to-heat ratio and second-law efficiency) are examined. An important conclusion of this study is that a regenerative gas turbine cogeneration system is capable of producing large power-to-heat ratios for various process conditions requiring the use of only moderate compressor compression ratio and moderately effective regenerators. It appears that this is an attractive system which could compete in a market that is currently dominated by internal combustion engines when a viable fludized bed air heater is available.

This paper describes coal-fired, indirectly heated, air turbine combined cycle cogeneration plants that employ atmospheric pressure external combustion of coal, an open cycle gas (air) turbine, and a steam turbine. Air to operate the air turbine is heated indirectly, by hot fluidized solids contained inside tubes. The result is a high efficiency system that burns coal (or almost anything that will burn), does not require extensive operator training or support facilities, and emits low quantities of sulfur, NOx and particulates. The plant is capable of supplying electrical power, process heat, steam, and clean hot air in varying quantities, depending on the application. Uses exist in the chemical, petroleum, mining, metallurgical, paper, and textile industries and in enhanced oil recovery.
