Siemens has committed to gradually increasing the hydrogen capability of its gas turbines to at least 20% by 2020, and 100% by 2030. The first goal has already been achieved, with projects in place involving two SGT-600 turbines at Braskem in Brazil.
Power demand is not restricted to safe and stable locations. Power plants also operate in locations where there is a high risk, be it man-made or natural hazards. Carrying out operation and maintenance on large, static power plants under such circumstances can be challenging, and dealing with these challenges requires planning and preparation one wouldn’t consider in secure locations. How does one deal with such challenges? GTW has been examining the issue.
A mechanical efficiency of 34.5% coupled with extremely low emissions makes the MGT 6000 gas turbine among the most modern designs in the 6 MW category. Combined heat and power plants equipped with this turbine achieve efficiency of up to 90%.
Tampa Electric to reuse 1970s- vintage steam turbine in highly efficient HA-class combined cycle repowering project to boost site power, improve efficiency, cut emissions.
Egypt has completed construction of three combined cycle gas turbine projects in just 27.5 months. GTW was part of a press visit to Beni Suef, one of the massive 4800 MW plants, which all use Siemens’ advanced H-class technology.
GE’s 6B gas turbine fleet has reached 40 years of operation, with the first unit starting up in 1978 and still running. Now, GE has reached its first agreement to repower three 6B gas turbines at a site in Asia.
Europe’s first GE 9EMax gas turbine upgrade has been carried out at an IPP project in the Czech Republic. The upgrade will not only boost plant performance but will also lower running costs and extend plant life.
The reliable prediction of thermal loads in transition pieces is crucial to increase their life span. Power Systems Mfg. LLC (PSM) discusses best practices in transition piece design to allow aerodynamic pieces that optimize and combine improved cooling effectiveness with low pressure drop and reduced emissions operation.
The first GT36 gas turbine – Ansaldo Energia’s advanced H-Class machine – has completed the first phase of a comprehensive validation program. The tests confirm the machine’s high performance and low emissions over the entire load range.
