In a typical cement producing procedure, 25% of the total energy used is electricity and 75% is thermal energy. However, the process is characterized by significant heat losses mainly by the flue gases and the ambient air stream used for cooling down the clinker (about 35%–40% of the process...

The pre-combustion carbon capture technology based on coal gasification or methane reforming followed by (water gas shift reactors assisted with Pd-alloys membranes) WGS-MR is considered very promising for the production of a rich hydrogen stream that can be combusted in combined cycles....

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....

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...

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...

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...

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 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.
