The generated power and efficiency of gas turbine plants depend on the temperature of the inlet air. At high ambient temperatures, a power loss of more than 20%, combined with a significant increase in specific fuel consumption, compared to ISO standard conditions (15 °C), can be observed.

Up to recently 2-D solid oxide fuel cell (SOFC) modelling efforts were based on global kinetic approaches for the methane steam reforming and water gas shift reactions (WGS) or thermodynamic equilibrium. Lately detailed models for elementary heterogeneous chemical kinetics of reforming (HCR)...

This paper presents an exergetic analysis of a combined heat and power (CHP) system, integrating a near-atmospheric solid oxide fuel cell (SOFC) with an allothermal biomass fluidised bed steam gasification process. The gasification heat requirement is supplied to the fluidised bed from the SOFC...

Coal and lignite will play a significant role in the future energy production. However, the technical options for the reduction of CO2 emissions will define the extent of their share in the future energy mix. The production of synthetic or substitute natural gas (SNG) from solid fossil fuels...

The present study presents a three-dimensional numerical model for co-firing lignite and biomass in large-scale utility boilers. The model takes into account the non-spherical form of the biomass particle, which influences the drag coefficient and its devolatilization and combustion mechanisms....

A cooling dominated Hybrid Ground Source Heat Pump System (HGSHPS) is utilized to cover the energy demands of an office building. The energy demands are computed by TRNSYS 16.1, considering two different scenarios, based on different glazing properties. A ground loop consisted of a rectangular...

This paper presents the energy policy of the Republic of Cyprus government controlled areas from 1960 till 2006. It describes the sectors of electricity, petroleum, natural gas and renewable energy sources. It also deals with the marine layers of oil and with environmental aspects.

Within the carbon constrained world, biomass-based power production is expected to constitute one of the candidates for CO2 abatement. However, within the framework of a liberalised energy market, biomass power systems must be competitive from efficiency and cost point of view for their...

The need for a practical, economic and environmentally sound solution for waste wood arises from the requirements for resource conservation and recent regulations. Co-firing with coal is a promising option for the thermal recycling of waste wood. The overall environmental impact caused by the...
