Controlling NO_xEmissions From Steam Generators

Effectiveness in the Use of Natural Gas for the Reduction of Atmospheric Emissions: Case Study—Industrial Sector in the Metropolitan Region of Santiago, Chile

“…PM, which results from the incomplete burning of natural gas, consists of hydrocarbons of high molecular weight. The resulting PM has a size smaller than 1 m. [5][6][7] METHODOLOGY Two scenarios were considered consisting of all of the stationary combustion sources from the industrial sector during 1997 and 2000, respectively. These two scenarios correspond to situations without and with natural gas, respectively.…”

Applying the Random Forest Method to Improve Burner Efficiency

“…When organizing the operation mode of the combustion devices of power plants, it is required to organize the influence of heat and mass transfer processes and aerodynamics on the ongoing chemical reactions in such a way as to ensure the most complete and environmentally friendly fuel combustion [1,2]. At high temperatures, a certain amount of toxic nitrogen oxides is formed in the combustion chamber in the form of NO, NO 2 , N 2 O 4 , N 2 O 5 , etc., along with emissions of SO 2 , CO 2 [3,4]. In calculations, it is conditionally assumed that nitrogen oxides emitted into the atmosphere consist only of NO 2 .…”

Energy utilization and environmental control technologies in the coal-electric cycle

“…However, by the utilization of a combination of control techniques, an average reduction in emissions of 37 percent has been achieved for coal-fired units (3). Higher reduction efficiencies are likely possible for specific situations; however, more research is required, especially for coal-fire power plants (76).…”
