High levels of power requirement and rising energy costs represent a major challenge for the steel industry. Gases created as a ‘free’ by-product during steel production processes serve as an attractive energy source option for efficient power generation. In addition to the economic benefit, using these gases as engine fuel reduced industrial CO2 emissions and saves natural energy sources. Substantial research has been completed on this application. Jenbacher installed its first commercial gas engine applications for coke gas in 1995 and for LD converter gas in 2004.
Coke Gas
A by-product of industrial coke production from pit coal, coke gas is created by high-temperature dry distillation of coking coals in the absence of oxygen. The gas mainly consists of hydrogen (50-60%), methane (15-50%) and a small percentage of carbon monoxide, carbon and nitrogen. With a calorific value of 5kWh/m3N, coke gas constitutes a high-value fuel for effective power generation with GE Jenbacher gas engines.
Blast Furnace Gas
Blast furnace gas is a by-product of blast furnaces where iron ore is reduced with coke into metallic (pig) iron. The gas has a very low heating value of around 0.9kWh/m3N, which on its own is typically not high enough for combustion in a gas engine. There is the possibility to blend this gas with other off gases and you should contact your local Clarke Energy office to discuss in more depth.
Converter Gas
Converter gas is created from pig iron during the steel production process. Steel-making technology can be categorised into two different processes: blow moulding or open hearth.
About 30 GE Jenbacher gas engines now run on either coke gas or LD converter gas. Underscoring GE’s technical expertise, these units recently reached a combined total of more than 1 million operating hours. In addition, by utilising these ‘free’ waste gases compared to using natural gas for power generation, the GE Jenbacher technology-equipped sites have achieved CO2 savings of about 2 million tonnes since commissioning.
