Thermodynamic analysis of a hybrid gas turbine/thermoacoustic heat pump/refrigeration engine
Possible performance enhancement of small gas turbine power plants through the application of thermoacoustic systems is examined. The thermoacoustic subsystem is powered only by the waste heat of the gas turbine. Two different gas turbine configurations are considered: a Thermoacoustic refrigerator assisted gas turbine (TRG) and a Combined thermoacoustic heat pump and refrigeration assisted gas ...

Quantifying Combined Heat and Power (CHP) activity
In CHP plants without heat rejection facilities power, output is complementary to the recovery of heat, and all activity is cogeneration. CHP plants with heat rejection facilities can operate a mix of cogeneration and condensing activities. Quantifying the energy flows of both activities properly requires knowledge of the design power-to-heat ratios of the CHP processes (steam and gas turbines, ...

Cogeneration Renovation of Cofely`s Saint Quentin Installation - Case Study
In 2012, Cofely’s Picardie branch, the site’s exploiter, entrusted the renovation of a cogeneration installation in Saint Quentin, in the Aisne province, to Clarke Energy. Initially, this “boiler room” consisted of a turbine installed in a soundproof enclosure. Cofely could either renovate the existing turbine, or replace it with a gas engine. Cofely’s main ...

EU regulation of combustion plant - A power industry perspective
Any installation that contains combustion plant with an aggregated thermal input greater than 50 MW is regulated under the Industrial Emissions Directive (IED) which requires that Best Available Techniques are applied to emissions control. Individual plant with a thermal input greater than 50 MW are regarded as Large Combustion Plant and additional provisions apply, including mandatory Emission ...

Diesel economy is the benefit for the future
Diesel fuel is a liquid product which is used as fuel in the diesel engine. It is received by oil distillation from kerosene and gas-oil fractions. It represents quite viscous and difficult evaporated combustible liquid. Generally it consists of carbons, some percentage of hydrogen, oxygen, sulfur and nitrogen. Such type of fuels is intended for high-speed diesel and gas-turbine engines of land ...

Design and Analysis of a High Pressure Ratio Mixed Flow Compressor Stage
I. Introduction Smaller frontal area and high thrust to weight ratios of mixed flow compressor stage has resulted in its application for small gas turbine engines in aviation sector [1] . The efficiency and reliability of the compressor depends to a great extent on flow behavior in its flow passage and its interaction between impeller and diffuser. The complex turning of the flow not only in the ...

SpectrOil — The Accurate and Dependable Choicefor In-Service Oil And Fuel Analysis
Introduction The basis of modern oil analysis programs is the use of optical emission spectroscopy (OES) to measure the ppm (parts per million) levels of wear metals, contaminants, and additives in oil samples. Whatever an oil lab may need to measure, multi-elemental analysis is the core of an in-service oil analysis program. This paper gives an overview of Rotating Disc Electrode Optical ...

Combined Heat and Power (CHP) essentials
'CHP essentials' introduces the concept of power and heat 'production possibility sets', starting at the cradle of CHP, i.e., the thermal power generation plant. The latter always occasions 'fatal' heat that is either recovered (the 'merit' of CHP) or wasted (condensing). This split paves the way to defining the production possibility sets of CHP plants, shown for steam turbines, internal ...

Guidetubes for wide range of turbine inspections
Guidetubes are a great accessory for your 4mm borescopes. The combination of borescopes and guidetubes allow you to inspect turbines without taking apart said turbine. They’re essential for directing borescopes into specific areas during the inspection process, and with the use of articulating borescopes, they’re perfect for snaking through tight spaces and around corners. Most ...
