Patent number: 10731846Abstract: A boiler facility includes a boiler having a combustion chamber in which a burner is installed, a fuel pipe for supplying fuel to the burner, an air duct for supplying air sucked by a blower to the boiler, an oxygen supplier having an oxygen pipe connected to the air duct and a flow rate controller provided in the oxygen pipe, and a control unit. The control unit sets an air amount that is smaller than the reference air amount for burning the fuel, and controls the blower so that the set air amount is supplied to the boiler. Further, the control unit sets an oxygen amount for fuel combustion, and controls the flow rate controller so that the set oxygen amount is supplied to the air duct.Type: GrantFiled: July 27, 2017Date of Patent: August 4, 2020Assignee: GEESCO CO., LTD.Inventor: Sung-Ho Hong

Patent number: 8916119Abstract: The present disclosure relates to a method for removing nitrogen oxides (NOx) more effectively at 300° C. or below in boilers, gas turbines, incinerators, diesel engines, glass melting furnaces, etc. by selective catalytic reduction (SCR). To this end, an oxidation catalyst is mounted in front of a NOx-reducing device based on selective catalytic reduction and the NOx composition, i.e. the ratio of NO:NO2, in the exhaust gas is adjusted to about 1:1, such that de-NOx catalytic reaction is carried out under optimized fast SCR condition and de-NOx efficiency at low temperature can be maximized.Type: GrantFiled: October 20, 2011Date of Patent: December 23, 2014Assignee: GEESCO Co., Ltd.Inventors: Dae Woo Kim, Ha Kue Park, Jae Pil Jung
