Abstract: Disclosed is a method for removal of an unburned carbon contained in a fly ash material. The method comprises the steps of adding water to the fly ash to prepare a fly ash slurry; shearing the fly ash slurry using an agitating blade that can rotate at a high speed to generate an active energy on the surface of an unburned carbon by the shearing force, thereby imparting lipophilicity to the unburned carbon; and adding a collecting agent and a foaming agent to the slurry containing the lipophylized unburned carbon to cause the attachment of the collecting agent to the lipophylized unburned carbon, and at the same time, causing the attachment of the unburned carbon having the collecting agent attached thereto an air bubble to separate the unburned carbon by flotation.

Abstract: A plasma generating apparatus is provided with an impedance matching member, which is connected to a feeding line that supplies an antenna element with a high frequency signal, and has variable characteristic parameters for impedance matching; a distribution wire, which is arranged corresponding to the impedance matching member and connects the impedance matching member with at least two antenna elements; and a control section which changes at the same time impedance matching statuses of at least the two antenna elements connected to the impedance matching member through the distribution wire by changing the characteristic parameters of the impedance member. Thus, the number of impedance matching devices is smaller than that of the antenna elements, and a mechanism relating to impedance matching is made relatively small.

Abstract: A denitration process for removing nitrogen oxides contained in low-temperature exhaust gas at a high denitration rate; namely, a denitration process for reductively removing nitrogen oxides contained in an exhaust gas (x) containing nitrogen monoxide and sulfur dioxide. The process comprises a preliminary step 2 of partially oxidizing nitrogen monoxide in the exhaust gas to form nitrogen dioxide, a radical formation step 3 of adding a nitrogen compound and a hydrocarbon compound to a high-temperature zone 22 to form amine radicals (r), and a denitration step 4 of mixing the amine radicals (r) with the pretreated gas (p) containing nitrogen monoxide and nitrogen dioxide that was discharged from the preliminary step 2. As a result, nitrogen oxides in the exhaust gas (x) are reductively decomposed.
