Most of the electric power produced worldwide is based on fossil fuel combustion, largely in plants operating with low efficiency cycles. The large amounts of fuel consumed in this process release harmful emissions including toxic nitrogen and sulfur oxides, mercury, and greenhouse gases such as carbon dioxide. The necessity to reduce the negative impact of power generation on the environment, ...

Due to the serious power shortage in Taiwan, many simple cycle gas turbine generation sets (GENSETs) that were originally designated to serve as peak load units are forced to operate continuously during the entire summer season. The retrofitting projects have been seriously considered to convert these GENSETs (which have the advantage of fast startup, but suffer from low power output and therma...

We show that a neural network can be successfully used in place of an actual model to estimate key unmeasured parameters in a gas turbine. As an example we study the combustion reference temperature, a parameter that is currently estimated via a nonlinear model inside the controller and is used in a number of critical mode-setting functions within the controller such as calculating the fuel-spl...

determination of the starter torque-speed diagram is a major task in the design or selection of a proper gas turbine starter. in this paper, the maximum power of the mgt-40 gas turbine starter was calculated based on the dynamics of the rotor, start-up logic, and compressor map. in a recent research, the pressure ratio was assumed as a linear function of the rotor speed and the required starter...

Biomass based Indirectly Heated combined heat and power plant can be an excellent option for community scale power generation. The thermal performance of such a plant employing air-turbo generator block and bottoming steam turbine block has been analyzed over a range of pressure ratio (2-16) and for different turbine inlet air temperatures (1073, 1273 and 1373K). The conventional GT combustion ...

With the adoption of a condition based maintenance philosophy, a major gas turbine engine manufacturer has initiated a project to develop and implement an Expert Diagnostic System (EDS) to supplement its automated machinery vibration condition assessment program. The goal of this work is to enhance operational readiness, to promote maintenance self-sufficiency and to reduce overall life-cycle c...

In this paper, an innovative power plant, constituted by a gas turbine in combined-cycle fuelled by a synthesis gas (or syngas), produced in a local biomass gasifier, is analyzed. The plant is integrated with an external combustion system, fed by cellulosic biomass, connected to a heat exchanger able to increase the air temperature, as in a regenerative cycle. The combustion products pass throu...
