GE Bats 1000 And 1001

Natural-gas powered engines used for power, steam, cooling for Salfi Textile Mills in Karachi

Posted on April 7, 2014

Tata Energy, a part of Tata Industries, has selected two of GE’s 3.3 MW Jenbacher J620 cogeneration gas engines to power Tata’s Salfi textile mills in Karachi, Pakistan’s largest city. The project represents GE’s 1000th and 1001st Jenbacher gas engines to be installed in the country.

In addition to generating electricity, the Jenbacher units also will recover heat from the engine exhaust to produce steam for the mill’s production processes and recover heat from the engine’s jacket water to produce chilled water to support cooling needs at the facility.

Capable of utilizing a variety of gas types including natural gas, flare gas, biogas, biomass, landfill gas and other gaseous fuel types, the Jenbacher engines will enable Tata to reduce its on-site energy production costs, gain greater electrical efficiency of 43.5% and further improve overall efficiency of the power plant by making effective use of the engine exhaust heat and jacket water heat, GE said. Once Tata installs the new engines by August 2014, the company plans to retire its existing, less-efficient generator sets.

The company said its Jenbacher engines generate a total of 1445 MW to power some of Pakistan’s major industries, including the energy, chemical and manufacturing sectors. This includes approximately 873 MW to Pakistan’s textile industry.
