摘要 |
A converter exhaust gas recovery apparatus includes a furnace top oxygen analyzer that analyzes an oxygen concentration in exhaust gas on an exhaust gas path and on an upstream side of a dust collection position where dust collection is performed and a furnace top CO analyzer that analyzes a CO concentration in the exhaust gas; and a furnace bottom oxygen analyzer that irradiates the exhaust gas that flows on a downstream side of the dust collection position with a laser light and analyzes the oxygen concentration based on quantity-of-light changes caused by a light absorption of the laser light. |
