Combined Heat and Power (CHP) essentials
'CHP essentials' introduces the concept of power and heat 'production possibility sets', starting at the cradle of CHP, i.e., the thermal power generation plant. The latter always occasions 'fatal' heat that is either recovered (the 'merit' of CHP) or wasted (condensing). This split paves the way to defining the production possibility sets of CHP plants, shown for steam turbines, internal ...

Towards an European Fuel Cell Strategy
Head of Unit 'Energy Consumption Technology' At the onset of the Fourth Framework Programme for Community research and technological development including demonstration, a ten year fuel cell strategy for Europe was published in 1995 jointly by DG XII (Directorate General for Science, Research and Development) and DG XVII (Directorate General for Energy). The interest of the European Community ...

Quantifying Combined Heat and Power (CHP) activity
In CHP plants without heat rejection facilities power, output is complementary to the recovery of heat, and all activity is cogeneration. CHP plants with heat rejection facilities can operate a mix of cogeneration and condensing activities. Quantifying the energy flows of both activities properly requires knowledge of the design power-to-heat ratios of the CHP processes (steam and gas turbines, ...

Thermodynamic analysis of an integrated gasification combined cycle power plant: effect of nitrogen supply on system performance
A comprehensive thermodynamic analysis of a conceptual integrated coal gasification combined cycle power plant is presented. Energy and exergy efficiencies and exergy destructions of each sub–unit are calculated. The effect of nitrogen, which is supplied from the Air Separation Unit (ASU) of the gasification unit to the combustion chamber of the gas turbine (GT) cycle, on system performance is ...

Exergy analysis of the steam-injected gas turbine
In this paper, the effect of steam injection in the combustion chamber on the exergy efficiency of a gas turbine was investigated. Cycle exergy efficiency, net power output and exergy destruction have been calculated for different mass flow rates and temperature of the injected steam. The range of variation of the mass flow rate was between 0 and 5.24% of the design air flow rate, and the ...

Comparative study of steam injection effects on operation of gas turbine cycles
In the present work, gas turbine cycles are modified with steam injection between the combustion chamber exit and the gas turbine inlet. Heat recovery steam generators, utilising the exhaust gases, provide these cycles with the injected steam at saturated vapour. The irreversibility of the different composing units of the cycles and the variation of gas properties owing to steam injection as well ...

Enhancing the dynamic performance of electricity production in steam power plants by the integration of transient waste heat sources into the feed-water pre-heating system
Since the deregulation of the energy market the enhancement of steam power plant's dynamic performance has become more and more important. Nowadays, peak load is a profitable product at the energy stock markets if it can be provided reliably. This is in contrast to many power plants running constantly at full load. A very promising technique to improve the peak load capability of such power ...
