Publication number: 20120102834Abstract: A gasifier system which includes a reactor; a feedstock inlet; an oxidant inlet; a raw product gas outlet; and a recycle conduit, is provided. The reactor usually includes an upper section, a central section, and a lower section. The feedstock inlet is disposed in the upper section of the reactor to receive a carbonaceous feedstock. The oxidant inlet is disposed in the lower section of the reactor to receive an oxidant. The raw product gas outlet is disposed in the upper section of the reactor. The recycle conduit is configured to couple the raw product gas outlet to the lower section of the reactor, and to recycle a raw product gas from the upper section of the reactor to the lower section of the reactor. A method for converting a carbonaceous stream into a product gas in a gasifier system is also provided.Type: ApplicationFiled: October 29, 2010Publication date: May 3, 2012Applicant: GENERAL ELECTRIC COMPANYInventors: Surinder Prabhjot Singh, Vitali V. Lissianski, Aaron John Avagliano, Wolfgang Madl

Patent number: 6863005Abstract: In a method to decrease emission of mercury, a factor is selected to control a combustion process to generate a flue gas comprising fly ash with enhanced unburned carbon; the combustion process is controlled according to a factor selected from reburning fuel, flue gas temperature, OFA injection, coal particle size, LNB flow, LNB design, combustion zone air, stoichiometric ratio of fuel, fuel/air mixing in a primary combustion zone and fuel/air mixing in a secondary combustion zone to produce the flue gas comprising fly ash with enhanced unburned carbon and to vaporize mercury; and the flue gas is allowed to cool to collect fly ash with enhanced unburned carbon with absorbed mercury. A system to decrease emission of mercury; comprises a combustion zone that is controlled to generate a flue gas comprising fly ash with enhanced unburned carbon and that produces vaporized mercury; and a post combustion zone to cool the flue gas to collect fly ash with enhanced unburned carbon with absorbed mercury.Type: GrantFiled: December 1, 2003Date of Patent: March 8, 2005Assignee: General Electric CompanyInventors: William Steven Lanier, Charles M. Booth, Vitali V. Lissianski, Vladimir M. Zamansky, Peter M. Maly, William Randall Seeker

Patent number: 6471506Abstract: Various methods for decreasing the amount of nitrogen oxides released to the atmosphere as a component of combustion gas mixtures are provided. The methods specifically provide for the removal of nitric oxide and nitrogen dioxide (NOx) from gas mixtures emitted from stationary combustion systems. In particular, methods for improving efficiency of nitrogen oxide reduction from combustion systems include injecting metal-containing compounds into the main combustion zone and/or the reburning zone of a combustion system. The metal containing compounds react with active combustion species, and these reactions change radical concentrations and significantly improve NOx conversion to molecular nitrogen. The metal-containing additives can be injected with the main fuel, in the main combustion zone, with secondary or reburning fuel addition, or at several locations in the main combustion zone and reburning zone.Type: GrantFiled: November 6, 2000Date of Patent: October 29, 2002Assignee: GE Energy & Environmental Research Corp.Inventors: Vladimir M. Zamansky, Peter M. Maly, Jerald A. Cole, Vitali V. Lissianski, William Randall Seeker

Patent number: 6280695Abstract: Methods are provided for decreasing the amount of nitrogen oxides released to the atmosphere as a component of combustion emissions. The methods are carried out by forming a combustion flue gas in a combustion zone, the combustion flue gas including nitrogen oxides, injecting overfire air and droplets of a solution or a powder of a selective reducing agent into a burnout zone, and contacting the combustion flue gas with the overfire air and the selective reducing agent in the burnout zone to thereby decrease the concentration of nitrogen oxides therein. The selective reducing agent is provided in an aqueous solution or powder which is injected into the overfire air in optimized droplet or particle form prior to or concurrently with injection of the overfire air into the burnout zone.Type: GrantFiled: July 10, 2000Date of Patent: August 28, 2001Assignee: GE Energy & Environmental Research Corp.Inventors: Vitali V. Lissianski, Vladimir M. Zamansky, Richard K. Lyon, Roy Payne
