Market needs for steam turbines, widely used as drives
for power generation facilities and oil-refining machines,
are increasing as a result of deregulations in the electric
power industry and construction of new industrial
waste disposal facilities. This paper reports the characteristics
of a "NewC4" completely standardized
steam turbine. "NewC4" is a steam turbine with an output
power of 2000 kW or less, targeted at small-size private
power generation facilities in Japan. To achieve
high efficiency, this turbine has a smaller size and higher
rotation speed than the conventional type. And, with
its oiling device serving also as the turbine bedplate,
the "NewC4" is compactly designed. In addition, it is
capable of performing unattended operation through a
hydrodynamic emergency shut-off valve. By completely
standardizing the new steam turbine, a low price and
short delivery time were achieved. |
