Gas, Steam Turbine Market Grew 339% in 1999
Unprecedented growth of nearly 339% last year in the gas and
steam turbine market was fueled by the rise in combined cycle
configurations, a manufacturing method that has dramatically
increased efficiency in electricity production and become
increasingly popular with power plant producers, according to a new
research report by Frost & Sullivan.
The report, "North American Gas and Steam Turbine Markets"
concludes that several factors have contributed to the turbine
industry's growth, which last year generated revenues of $8.22
billion. Researchers believe that there will be continued strong
sales through 2006, mostly because of the combined cycle
configuration. Some turbine manufacturers are reporting order
backlogs now stretching to 2004.
In this configuration, one or more gas turbines are combined
with a steam turbine, and as exhaust is discharged from the gas
turbine, the fumes are captured in a heat recovery steam generator,
and thus, drive the steam turbine.
"This type of configuration is often near 60% efficiency,
compared to a single gas turbine in a simple cycle that generates
35% to 40% efficiency," said analyst Max Mayer. "This configuration
has contributed to the market for associated products like steam
turbines and heat recovery steam generators, which have both shown
solid increases in sales."
The combined cycle configuration allows more versatility for
power producers. With a two-gas, one-steam turbine configuration,
one of the gas turbines may be turned off during low-load or
maintenance periods, while the rest of the machine runs at an
Gas turbine manufacturers and power plant producers are
especially interested in the market's outlook and plan to focus in
the next several years to bringing more combined cycle systems on
line, especially in high brownout areas and regions with high
"Improving efficiency rates is a driving force in turbine
technology," Mayer said. "Turbines are the most efficient
generating source in combustion technology used to create
electricity. Slight improvements in efficiency percentages
translate to lower costs for power plants and thus lower prices for
