20130298809 | METHOD FOR CONTROLLING NOX CONCENTRATION IN EXHAUST GAS IN COMBUSTION FACILITY USING PULVERIZED COAL - An object of the invention is to provide a method for controlling an NOx concentration in an exhaust gas in a combustion facility that uses a pulverized coal, which can easily control the NOx concentration in the exhaust gas to be discharged from a fuel facility that uses the pulverized coal as the fuel to or below a regulation value according to the Air Pollution Control Law and the like, and can also reduce an amount of a denitrifying agent or the like to be used, which is necessary for the control, by controlling the NOx concentration on the basis of the properties of the pulverized coal beforehand. The invention further includes: measuring a reaction velocity of each of chars corresponding to a plurality of types of pulverized coals beforehand; determining a relationship between the NOx concentration in the exhaust gas and the reaction velocity in advance; blending the plurality of the types of the pulverized coals so that the reaction velocity of the char becomes such a value as to correspond to a target NOx concentration or below, on the basis of the relationship; and supplying the blended pulverized coal to the combustion facility as the fuel of the combustion facility. | 11-14-2013 |
20140120486 | CEMENT PLANT - There is provided a cement plant including a chlorine bypass apparatus capable of efficiently reducing the chlorine concentration in a cement kiln due to exhaust gas extraction by a small amount, by preventing calciner exhaust gas low in chlorine concentration from contamination and extracting a part of kiln exhaust gas high in chlorine concentration. In the invention, a baffle wall | 05-01-2014 |
20140366499 | CHLORINE BYPASS DEVICE - The present invention provides a chlorine bypass device which can cool exhaust gas quickly by mixing extracted exhaust gas with cooling air at high efficiency, thereby produce fine chloride dust, and increase dust recovery efficiency.
