JFE Steel Corporation has ordered a GE 9E gas turbine as well as a GE-designed 9A5 generator and associated equipment at its new 150 MW combined-cycle power plant. JFE's East Japan works produces about 8 million tons of crude steel annually, according to JFE.
Mitsubishi Heavy Industries Ltd in collaboration with Sinosteel Equipment & Engineering Co Ltd of China has received an order for two blast furnace gas fired gas turbine combined cycle power generation plants from Baotou Iron & Steel Co Ltd also of China. The power plants will be installed in Baogang expansion of their steelworks with the aim of effectively utilizing exhaust gas from blast furnaces and coke ovens on the premises to meet part of its electricity needs. MHI is the world's leader in the BFG-GTCC power generation system market.
In an opening ceremony on August 10, 2012, Northern California Power Agency (NCPA) officially dedicated the Lodi Energy Center (LEC). The new plant with an installed capacity of 300 MW is located in Lodi, California.
One of the most important factors that should be considered in the design (and operation) of any turbomachinery is the thermal structure (or the thermal arrangement). Appropriate materials, cooling systems and insulations (or thermal shields) should be selected for turbomachinery based on a proper thermal analysis.
ABB and Ansaldo Energia present new turbine control system
August 5 2012 -
ABB and Ansaldo Energia recently introduced the first turbine control system based on Symphony Plus technology. The new control system, developed specifically for Ansaldo Energia gas and steam turbines, has many pluses: reduced global management costs when compared with previous versions, better safety (also in relation to cyber security) and improved plant reliability and availability, in addition to greater management flexibility.
"My hobby is energy efficiency,” proclaimed Dr. Werner Janik, who sat down with Turbomachinery International at PowerGen Europe, in June. ABB’s global head of sales for Energy Efficiency and Service in Power Generation, discussed his experience helping energy facilities.
The original Digital Control System (DCS), Honeywell’s TDC 2000, began a revolution in industrial process control. What had previously been the realm of operators and pneumatic control systems slowly began to migrate into a microprocessor-based control chassis.
The history and evolution of turbomachinery control was linked to this progression, but it also took its own course, with specialists emerging, who focused solely on control, regulation and protection of the turbomachinery.
