    摘要: [PROBLEM] To provide a valuable substance recovery device, etc. that can keep equipment costs and operation costs low and can reduce a burden of gas processing after secondary combustion.
    [SOLUTION] A valuable substance recovery device 1 provided with a calcining furnace 11 that is attached to a cement firing device 2 and a return path 12 for returning an exhaust gas from the calcining furnace to the cement firing device. By effectively utilizing heat generated by the cement firing device in the calcining furnace for recovering valuable substances, equipment for supplying fuel for the calcining furnace becomes unnecessary and operation costs can be kept low. Acidic gases can be processed using a large amount of CaO present inside the cement firing device, making special processing device for processing the acidic gases unnecessary and making it possible to reduce equipment costs and operation costs significantly compared to the past. The calcining furnace is able to take in heat from a lower portion thereof and discharge the same from the return path, and can return the calcining furnace exhaust gas to an 800°C or higher temperature region of the cement firing device via the return path.

    摘要: To provide a method and facility for enabling CO 2 gas generated in a cement manufacturing facility to be separated and recovered at a high concentration. To this end, according to the present invention, the calcination of a cement material and the recovery of CO 2 gas generated in a calciner are performed by one of the following steps of: [1] superheating the cement material before calcination to at least the calcination temperature thereof in a superheating furnace and then mixing the superheated cement material with a new cement material before calcination in a mixer/calciner; [2] mixing, in the mixer/calciner, the cement material before calcination with a part of high-temperature cement clinker discharged from a cement kiln; and [3] using an externally heated calciner.

    摘要: A burner for pulverized coal has a coal duct (1) for pulverized coal and primary combustion air and a secondary combustion air duct (2) such that the coal and primary air and secondary air mix outside the outlet nozzles of the duct in a mixing zone at which combustion occurs. Coal distribution means (7) in the coal duct create, adjacent the outlet nozzle, at least one outer zone of flow spaced from the coal duct axis and at least one inner zone of flow nearer the coal duct axis. There are means (12) for slowing flow in the outer zone relative to the flow in the inner zone, prior to the mixing zone. To achieve good mixing, and promote NO x reduction, the coal concentration in the outer zone is higher than in the inner zone. The slowing means (12) may be radially inwardly projecting baffles.
