Abstract
Steel work gases (blast-furnace gases, coke-oven gases, converter gases, etc.) are burnt with an exhaust gas from a gas turbine, optionally with a supply of natural gas and of air, in a combustion section between the outlet of the gas turbine and the inlet of a recovery boiler, the steam from which is utilized especially for producing electrical energy.
Claims20
A combined installation located adjacent a steel work plant producing waste gas, the installation comprising:
- a gas turbine having an exhaust gas outlet supplying turbine exhaust gas;
- a recovery boiler having a hot gas inlet;
- a combustion section located between the exhaust gas outlet and the hot gas inlet;
- supplying means for supplying at least part of a waste gas from a steel work plant;
- and
- burner means, connected to the supplying means, for burning at least part of the waste gas in the combustion section to provide heat to the recovery boiler.
A gas treatment installation, comprising:
- a gas turbine unit having an exhaust hot gas outlet;
- a combustion section connected to the exhaust hot gas outlet and having a combustion section gas outlet;
- a recovery boiler having with a hot gas inlet section connecting to the combustion section gas outlet, the recovery boiler providing boiler exhaust gases;
- burners located in the combustion section to provide heat to the recovery boiler;
- and
- a gas feed line connected to the burners for supplying a waste gas to the burners from a work plant producing the waste gas.
A gas treatment installation, comprising:
- waste gas lines from a steel plant;
- a gas turbine unit having an exhaust hot gas outlet;
- a combustion section connected to the exhaust hot gas outlet and having a combustion section gas outlet;
- a recovery boiler having with a hot gas inlet section connecting to the combustion section gas outlet;
- and
- burners located in the combustion section and connected to the waste gas lines, the burners providing heat to the recovery boiler using waste gas receiving from the waste gas lines.
