Biomass based Indirectly Heated combined heat and power plant can be an excellent option for community scale power generation. The thermal performance of such a plant employing air-turbo generator block and bottoming steam turbine block has been analyzed over a range of pressure ratio (2-16) and for different turbine inlet air temperatures (1073, 1273 and 1373K). The conventional GT combustion ...

This paper describes a construction and characteristics of a coal-gas-burning high e ciency power plant which emits no carbon dioxide (CO 2 ) into the atmosphere. In the plant, CO 2 gas and superheated steam are used as the main and sub working uid, respectively, of a closed dual uid gas turbine power generation system. It is assumed that a coal gas whose principal compositions are CO, H 2 , CO...

Maintainability is an important character which is given by product design process. The maintainability design criteria and measure index used in product maintainability analysis are summarized and discussed in this paper. A product maintainability design method is studied by integrating the product feature model, maintainability design criteria with measure index. Product feature model can be ...

This paper presents a hydrogen powered hybrid solid oxide fuel cell-steam turbine (SOFC-ST) system and studies its optimal operating conditions. This type of installation can be very appropriate to complement the intermittent generation of renewable energies, such as wind generation. A dynamic model of an alternative hybrid SOFC-ST configuration that is especially suited to work with hydrogen i...

This document sets forth procedures for establishing maximum emissions levels for all fossil-fuelbased thermal power plants with a capacity of 50 or more megawatts of electricity (MWe) that use coal, fuel oil, or natural gas.1 Conventional steam-producing thermal power plants generate electricity through a series of energy conversion stages: fuel is burned in boilers to convert water to high-pr...

In this publication, we present an energy and exergy analysis of the Szewalski binary vapor cycle based on a model of a supercritical steam power plant. We used energy analysis to conduct a preliminary optimization of the cycle. Exergy loss analysis was employed to perform a comparison of heat-transfer processes, which are essential for hierarchical cycles. The Szewalski binary vapor cycle cons...

exergy analysis of an integrated molten carbonate fuel cell-turbo expander-steam turbine hybrid cycle has been presented in this study. the proposed cycle has been used as a sustainable energy approach to provide a micro hybrid power plant with high exergy efficiency. to generate electricity by the mentioned system, an externally reformed molten carbonate fuel cell located upstream of the combi...

the exergy analysis is a proper method for performance evaluation of industrial systems. a generic and detailed analysis of the gpcss on the second gas pipeline of iran  is made by the means of exergy. the two main improvement measures of fuel pre-heating and steam injection technologies are presented for the current conventional stations. steady state equations regarding the second law of ther...
