7FA Dual-Fuel Nozzle conversion

A recent project involved the installation of six Frame 7 Dry Low NOx 1.0 Dual Fuel units in Venezuela, and a decision was made to convert the fuel nozzles from a gas-only unit to a dual-fuel configuration. This decision was taken after determining that the lead time to supply all of the required sets would not meet schedule demands.

Hydrogen fuel blending system for GE 7FA turbines

GE 7FA Gas Turbines equipped with Dry Low NOx (DLN) combustion systems are often deployed in 100% pipeline natural gas applications. Although natural gas is available, some industrial and petrochemical sites prefer to look for ways to utilize process gases produced on-site to reduce plant operating costs.

Double impact: gas and steam turbines

In the previous part of this series, we saw how energy efficiencies of aircraft jet engines jumped, and how significant advancements were made further. In this article, we will discuss combined cycles.

2.5MW condensing turbine generator shipped to HTC campus

A new program: "Turbine Generator Maintenance, Inspection and Repair," which includes the construction and presentation of a 2.5MW condensing turbine generator, was recently started during during TGM's bi-annual Operations and Training Seminar at High Tech Central (HTC) Main Campus, 3800 Michigan Avenue, Fort Myers, FL. Although small, this particular turbine generator is representative of much larger units used in power plants throughout Florida and the US.

Electric vehicles

Every 10,000 miles driven in an electric vehicle (EV) equates to the amount of power needed by one home in the USA for a year, said Donald Karner, President and CEO of electric vehicle (EV) vendor ECOtality North America, at this year’s PowerGen conference.

New engine modifications for greater output and efficiency

Industrial gas turbine performance by OEMs and the bold moves taken by GE and Westinghouse to produce larger units were discussed in the third part of this series. More innovative models and modifications were introduced by Brown Boveri and GE in the coming years, for greater efficiency.

Southern Research develops new methods to capture pollutants

Engineers and technicians at the Birmingham-based Southern Research Institute have come up with new methods to measure the levels of mercury, trace elements, hydrogen chloride, and fine particles being emitted from power plants. Robert Dahlin, director of Southern Research's Power Systems and Environmental Research in Alabama said many plants have already installed or are in the process of installing scrubbers that can be optimized for capturing certain pollutants.

Art Titus is Elliott Group's COO

Elliott Group recently announced that Art Titus has been named Chief Operating Officer, succeeding outgoing COO Tony Casillo, who retired in December after 36 years with Elliott. Over the past six years, Tony Casillo led Elliott through a period of sustained growth and the closer integration of our global operations, said Yasuyuki Uruma, CEO of Elliott Group.

Invention of early jet engines and industrial gas turbines

The Rankine Cycle described in the second part of this series is working hand in glove with the gas turbine Brayton Cycle and has given us remarkable energy savings. With an improved part load heat rate, 65% combined cycle efficiency is targeted by 2016, which does not seem to be a distant dream.

GE technology to drive South Korea's first IGCC plant

Korea Western Power Co. (KOWEPO) has selected GE technology for its first integrated gasification combined-cycle (IGCC) power plant to be built in South Korea. The 300-megawatt "cleaner coal" facility, one of the first in Asia, will help the South Korean government meet its low carbon emissions targets, while bolstering the country's electricity supply.
