Experimental investigation of the characteristics of NOx emissions with multiple deep air-staged combustion of lean coal

Fuel, 2020
Deep air-staged combustion is the most promising low-NOx combustion technology to reduce NOx emissions. Both the single and multiple air-staged combustion were adopted to understand the NOx evolution behaviors and to explore the efficient NOx reduction ...

Anthropogenic emissions of SO2 and NOx in Asia: Emission inventories

Atmospheric Environment, 1992
Abstract The anthropogenic emissions of SO2 and NOx for 25 Asian countries east of Afghanistan and Pakistan have been calculated for 1975, 1980, 1985, 1986 and 1987 based on fuel consumption, sulfur content in fuels and emission factors for used fuels in each emission category.

NOx emissions prediction based on mutual information and back propagation neural network using correlation quantitative analysis

, 2020
Information on Nitrogen oxide (NOx) concentrations play a significant role in aftertreatment systems. In this work, a method to estimate NOx emissions by means of mutual information (MI) and back propagation neural network (BPNN) was introduced.

Computations of NOx Emissions of Domestic Boilers

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2001
AbstractDue to severe regulations concerning pollutant emissions, practical devices using combustion to release energy must be designed from the start using accurate, predictive numerical tools. A partially premixed methane/air flame in a two‐dimensional configuration is investigated in this work.

NOx Chemistry and Emissions — I

2000
Nitrous oxide (N2O) concentrations in the atmosphere increase at an estimated rate of 0.7–0.8 ppb per year. The combustion of solid fuels and waste at lower temperatures (750–900 °C) constitutes a significant source of N2O. During stages of a coal particle combustion (pyrolysis-devolatilisation and char combustion) both volatile-N and char- N are ...

Kinetics modeling of NOx emissions characteristics of a NH3/H2 fueled gas turbine combustor

, 2020
The two major challenges for ammonia combustion in gas turbines are its high NOx emission and low burning velocity. Recently, while H2 doping has been proved as an effective means of improving the NH3 burning velocity, there is a knowledge gap on the ...

Modelling of In-Line Low-NOX Calciners—NOX Emission

Chemical Engineering Research and Design, 2003
The influence of the air combustion mixing into the main flow, operating conditions and fuel type on the level of NO emission in the in-line low-NO x calciners was investigated. The analysis was carried out using a heterogeneous mathematical model based on non-isothermal diffusion-reaction models for char combustion and limestone calcination.

Contributions of aircraft emissions to the atmospheric NOx content

Atmospheric Environment, 1997
Abstract The relative contribution of aircraft emissions to the total atmospheric NOx content is studied by means of the atmosphere general circulation model ECHAM, which was extended by a simplified (linear) NOx chemistry module with NOx and HNO3 as prognostic variables.

Nonlinear modeling of industrial boiler NOx emissions

Journal of the Air & Waste Management Association, 2022
Pollutant emissions into the atmosphere are recognized as a significant problem in fossil fuel combustion. The pollution emission measurement in industrial boilers is difficult and expensive but fundamental for monitoring and controlling. Frequently continuous emissions monitoring (CEM) system is out of service or useless due to obsolescence, high ...

Computational investigation of NOx emission in biogas combustion

Environmental Science and Pollution Research, 2023
Landfills and anaerobic digesters in the waste treatment processes generate biogas. Biogas can be used as a fuel and excess biogas is typically burned in a flare to reduce the greenhouse effect. However, burning biogas produces several pollutants, including CO2, NOx, and SO2.
