Siemens adds further performance
category to its entrained-flow gasifier portfolio
May
15, 2014 + + + Siemens Energy is adding a new
high-performance model, the SFG-850, to its range of entrained-flow
gasifiers. The SFG-850 is designed to enhance the profitability of future
gasification plants by reducing specific plant costs, along with the
associated production costs of synthesis gas. An SFG-850 gasifier can
convert around 3,000 metric tons of coal per day into more than 5 million
standard cubic meters (Nm3) of high-quality synthesis gas. The SFG-850 was
introduced to the market at the end of March 2014.
With a length of 22
meters, an outer diameter of 4.8 meters and weighing in at 380 metric
tons, the SFG-850 gasifier is among the world’s largest and most economic
entrained flow gasifiers. The new model can be completely fabricated and
tested at the factory. Despite its size and weight, the unit can be
transported to its installation location in one piece eliminating the time
and expense of field fabrication.
The SFG-850 gasifier
is based on the same technical design as Siemens’ current gasifier models,
the SFG-200 and SFG-500, which are operating at plants around the world.
The proven central burner design, and dry feed system have now been
optimized further in the SFG-850. As with its predecessor models the new
model stands out because of its high degree of fuel flexibility. All of
the proven advantages of Siemens gasifier technology, including its short
startup and shutdown times, and the tried-and-tested serviceability of its
water-cooled design contribute to its ability to maintain the high levels
of availability of today’s Siemens fleet.
The synthesis gas
produced using the SFG-850 can be used in large-scale chemicals projects,
such as for producing CTL, SNG, methanol or polypropylene, or for the
production of clean transportation fuels. In addition, Siemens can offer
an optimized configuration of gasifiers and latest-generation Siemens gas
turbines with the new SFG-850 gasifier. This will make power generation in
IGCC (Integrated Gasification Combined Cycle) plants more economically
appealing and, hence, more competitive than current solutions.
