timesDevelopment of High Efficiency Gas Turbine Combined Cycle Power Plant
Methods of CO2 reduction to prevent global warming can
be divided into two types: reduction of CO2 emissions and
recovery of CO2.
Over the last one or two years CO2 recovery has been
studied for a combined system of hydrogen gas turbine
combined cycle and EOR (enhanced oil recovery), where
petroleum coke is gasified and the gas is shifted by reforming
to CO2 and hydrogen.
It is well-known that power plants are responsible for
one third of the total CO2 emissions. Improving the heat
efficiency of a power plant by introducing a high-efficiency
gas turbine combined plant with an advanced gas turbine
leads directly to the reduction of CO2 emissions, and is
therefore an effective means of CO2 reduction.
This paper reports the gas turbine combined cycle plant to
reduce CO2 emissions, and describes its future prospects of
high efficiency.

timesBrayton Cycle: The Ideal Cycle for Gas-Turbine Engines
Power generation is an important issue today, especially on the West Coast. Demand is outweighing supply because of lack of incentives for the utilities industry to build additional power plants over the past 10-20 years. Electrical innovations (such as the personal computer) were not accounted for in earlier predictions of power utilization and, now, the country is in dire need of streamlining the current power plants while pushing through as many applications as possible for new power plants. In response to this situation, power generation engineers will be in high demand. These engineers must have a thorough understanding of thermodynamics and, in particular, the Brayton cycle.

timesFluid Mechanics, Thermodynamics of Turbomachinery
Two main categories of turbomachine are identified: firstly, those which absorb
power to increase the fluid pressure or head (ducted fans, compressors and pumps);
secondly, those that produce power by expanding fluid to a lower pressure or head
(hydraulic, steam and gas turbines). Figure 1.1 shows, in a simple diagrammatic
form, a selection of the many different varieties of turbomachine encountered in
practice. The reason that so many different types of either pump (compressor) or
turbine are in use is because of the almost infinite range of service requirements.
Generally speaking, for a given set of operating requirements there is one type of
pump or turbine best suited to provide optimum conditions of operation. This point
is discussed more fully in the section of this chapter concerned with specific speed.

timesCivil Jet Engines Technology Speed
Abstract. In this paper, the speed of technology of civil jet
engines is investigated. A fundamental limit is found to
exist by the second law of thermodynamics, but it is not
reached yet. A technology measure based on airplane
efficiency is derived and applied to jet airlines of different
sizes and time periods, ranging back to the 1960’s.

timesHeavy-Duty Gas Turbine Operating and Maintenance Considerations
Maintenance costs and availability are two of
the most important concerns to the equipment
owner. A maintenance program that optimizes
the owner's costs and maximizes equipment
availability must be instituted. For a maintenance
program to be effective, owners must
develop a general understanding of the relationship
between their operating plans and priorities
for the plant, the skill level of operating
and maintenance personnel, and the manufacturer's
recommendations regarding the number
and types of inspections, spare parts planning,
and other major factors affecting component
life and proper operation of the equipment.

timesGAS TURBINE TUTORIAL-MAINTENANCE AND OPERATING PRACTICES EFFECTS
the paper covered in detail degradation mechanisms and the impact of component degradation on overall gas turbine performance.
Proper design and selection of inlet systems and fuel treatment systems, together with proper maintenance and operating practices can significantly affect the level of performance degradation and thus time between repairs or overhauls of gas turbine. the authors have avoided presenting figures about the speed of degradation, because it is subject to a variety of operation and design factors that typically cannot be controlled entirely.

timesCombined Cycle Systems For the Utility Industry
BASIC POWER PLANTS:
There are many types of power generating power plants. The basic features of the three
most common types are described below. The steam plant, the simple cycle peaking
units and the combined cycle power plants basic features are described below. After the
basic features are described, much time will be spent on the combined cycle plant and the
components that make up such a power generation facility.
