The classical gas turbine process is characterised by air compression from its surroundings, heating fuel in the combustion chambers, hence causing created flue gases to expand and thus induce mechanical action. performance of depends on anything that affects airflow density and/or mass at compressor inlet. most obvious changes a reduction power an increase specific consumption following ambien...

In the marine engineering industry, turbocharged diesel engines are often used to generate electricity, and hot oil can be extracted after generating electricity. However, engine heat recovery distinguished from gas for nonturbocharged systems. The ideal air model Brayton cycle is evaluate feasibility of turbocharged/nonturbocharged cogeneration retrofits in systems, paper designed effect press...

Recently, cogeneration systems (CGS) have been installed in various factories and buildings. CGS is usually connected to various facilities such as refrigerators, reservoirs, and cooling towers, and produces various energies for electric loads, air-conditioning loads, heating loads, and hot water loads (fig.1). Since daily load patterns of the various loads are different, optimal operational pl...

Proton exchange membrane fuel cells (PEMFCs) are highly efficient power generators, achieving up to 50-60% conversion efficiency, even at sizes of a few kilowatts. PEMFCs have zero pollutant emissions when fueled directly with hydrogen, and near zero emissions when coupled to reformers. These attributes make them potentially attractive for a variety of applications including electric vehicles a...

The energy crisis in recent years has led to the use of thermodynamic cycles that work based on renewable energies. Low-temperature cycles—such as organic cycles—are suitable strategies for the application of renewable energies. The present study proposes a novel cycle through the integration of a two-stage compression refrigeration cycle with a combined Rankine power and ejector refrigerat...

Combined heat and power plants (CHPPs) allow for significant savings in primary energy resources a reduction environmental pollution. Mostly it is carried out using steam turbines. However, the eighties of twentieth century, new promising direction development cogeneration appeared. These are operating on organic Rankine cycle (ORC). An analysis innovations abroad required adaptation this to Ru...

It is expected that residential units may replace   traditional heat and power production systems with cogeneration ones. Among the different cogeneration systems, fuel cell based systems are a suitable choice due to their high efficiency, high power density, low emission and low noise. In this paper, a cogeneration system based on solid oxide fuel cells is examined. The system, including the f...
