Definitions
- WO-2005/024398 it is known to measure the quantity of chemical species contained in a gas resulting from a metal treatment furnace, such as an electric arc furnace or a converter, by sampling a portion of the gas to be analyzed, its cooling to less than 300 ° C and measuring the amount of CO and / or CO 2 present in the gas using the coherent light signal emitted by a laser diode, said method providing a measuring said quantities with a response time of less than 10 seconds and a control of the oven in real time.
- a metal treatment furnace such as an electric arc furnace or a converter
- the main oxidant and the combustible material are injected into the combustion chamber at controlled flow rates, the combustible material is burned with the main oxidant in the combustion chamber, producing thermal energy. and fumes at a temperature above 600 ° C in the combustion chamber, and exhaust fumes thus produced from the combustion chamber through a discharge conduit.
- the exhaust fumes may contain residual oxidizable materials.
- the exhaust duct is provided with a diluent oxidizer inlet downstream of the combustion chamber.
- the residual oxidizable materials of the flue gases are burned with the dilution oxidant to obtain a flame inside the exhaust duct at the dilution oxidizer inlet.
- the flame intensity is detected inside the evacuation pipe and the main oxidant injection rate in the combustion zone is regulated as a function of the flame intensity detected.
- the process may be a batch process, a semi-batch process or a continuous feed process.
- the dilution oxidant inlet is typically an ambient air inlet in the exhaust duct (in English: "air gap"), but may also be an oxidant injector, such as an air injector enriched with oxygen or oxygen.
- the energy efficiency of the furnace 2 is significantly improved and effective treatment of fumes, including their filtering, is ensured.
