Case Study of a Typical Underperformed Waste Heat Recovery Power Plant and Remedial Measures
Abstract: With the development of technology, the efficiency of combined-cycle gas turbine (CCGT) has crossed the barrier of 60%. In this paper, a typical problem of low-output generation of a CCGT plant is analysed. During 1st four months of operation of the plant, the sustainable steam turbine power output was between 36 and 36.5 MW against the design output of 37.2 MW. This marginal drop is acceptable considering the degradation factor …

A study on effects of mass flow rate and compressor pressure ratio on gas turbine cycle performance
Abstract: Gas turbines are rotating machines that work based on the energy of gases from combustion. Each gas turbine includes a compressor to compress air, a combustion chamber to mix air with fuel and ignite it, and a turbine to convert the energy of the hot, compressed gases into mechanical energy. Gas turbines have many advantages over steam turbines, such as small volume, quick installation, quick start-up, easy operation and the …

Design and Fabrication of Pedal Operated Air Compressor
Abstract: The first idea for powering the pump would be a stationary bicycle. Pedal power is simple, efficient, and practical. Its most familiar use is the bicycle for personal or cargo transportation. But pedals can also power small stationary machines. Since the system is to remain human powered and large amounts of power are required, having the operator use their stronger leg muscles was intuitive. A stationary pedal driven device seemed …

A Review on working of Gas turbine Operation
Abstract: The basic operation of a gas turbine is a Brayton cycle with air as the working fluid. Atmospheric air flows through the compressor, increasing its pressure. Energy would then be tried to introduce by spraying fuel into the air and igniting it to build a high temperature flow. This superheated steam gas enters a turbine, producing shaft work output in the process. The unutilized energy can be generated in the …

A Review on Two-Area Hydro-thermal Power System
Abstract: In a two-area system, there will be one automatic load frequency control (ALFC) loop for each control area. Practical aspects considered in this system are reheat turbine in thermal power plant and mechanical governor in hydro-power plant. Reheat turbine improves the efficiency of the system as it again utilizes the steam coming out from high pressure turbine (HP) to run the intermediate pressure (IP) turbine and low pressure (LP) turbine.Keywords: …
