Helping to meet industry challenges

To meet these challenges, the high volume of coke, blast furnace, and converter gases created in metals production and processing can be captured and used to efficiently fuel power generation for the industry. Using these gases to power turbines in power plants instead of discarding them as waste can help the industry save money and reduce harmful industrial CO2 emissions.

GE’s portfolio includes heavy-duty and aeroderivative gas turbine packages that can run on these alternative gases, as well as power conversion and productivity solutions created to help the metals industry operate more efficiently and cleanly.


The ability to handle a range of process gases

GE’s portfolio includes technologies that can capture, clean, and process gases produced during metals processing to power its turbines.

  • Coke oven gas is a byproduct of coal carbonization, or heating coal at a high temperature in the absence of air. This is used by the steel industry to convert iron ore. Coke oven gas is a combustible hydrogen and hydrocarbon gas mix that can be cleaned and used as a fuel source to generate energy.
  • Blast furnace gas (BFG) is a byproduct gas released when iron is converted with coke in a blast furnace. This BFG fuel—a combination of nitrogen, carbon dioxide, carbon monoxide, and a small amount of hydrogen—has a low combustion value on its own, but it can be combined with coke oven gas or natural gas to sustain combustion.
  •  Converter gas is a byproduct gas produced in the steel production process when iron ore is refined to liquid steel by refining it with oxygen or air, reducing its carbon levels, and providing adequate process heat or by extracting oxygen from the iron and then processing it with an additional heat supply, often electrical melting. It is primarily made up of carbon monoxide, as well as carbon dioxide and nitrogen plus small amounts of hydrogen and methane.

GE’s portfolio of gas turbines for the metals industry

GE offers a range of aeroderivative and heavy-duty gas turbines able to operate with alternative fuels based on common byproducts of the metals industry, such as coke oven gas, blast furnace gas, and converter gas. GE’s fuel treatment, turbines, and conditioning and fuel-delivery system allow for power generation in this industry that is cost-effective, efficient, and more environmentally friendly.

Generating cleaner electricity at Handan iron and steel

The 170-megawatt power plant at Handan Iron & Steel Group Ltd's mill in Handan City, China, selected GE technology to help use emissions from iron and steel production to generate cleaner electricity. Instead of burning waste gas in a boiler, off-gas from Handan's blast furnace and coke oven now power a GE 9E gas turbine to generate power.

"We're being challenged to advance our thinking and find new paths to growth. But this idea goes even further—we're not simply doing the same things better, we're doing something completely new. And that will have a huge impact on our efficiency, energy costs and carbon footprint."

Mr. Li Fujun

General director, power and equipment of Handan Steel Mills

Benefits to the Handan mill include higher efficiency and more output with fewer emissions when compared to traditional boiler technology for steel mills with blast furnace gas, coke oven gas, or Finex gas as byproducts of the steel mill process. The GE 9E gas turbine has also reduced costs for Handan by enabling them to buy less electricity from the grid with fewer emissions and a smaller footprint. GE’s power solutions are helping the Handan plant meet a variety of government objectives, including increased non-fossil fuel energy production, lower water consumption, greater energy efficiency, and reduced CO2 emissions.
