Two boiler combustion models are proposed in this paper: one is a mathematical model describing the key dynamics of the real-time boiler thermal efficiency and the furnace one-dimensional NOx concentration distribution under conventional fuel and overfire air operations; the other recast from the first model is a control-oriented grey-box model with a data-driven furnace combustion submodel.
A minimum period of 30 min was between NOX-C89 infusion and the second CGRP-testing, which might be necessary for NOX-C89 distribution.
Results of a parametric study in a producing horseshoe furnace by increasing the height of the furnace with regard to NOx concentration distributions are presented.
The equipment of the van provides gas phase measurements of CO and NOx, number size distribution measurements of fine and ultrafine particles by an electrical low pressure impactor, an ultrafine condensation particle counter and a scanning mobility particle sizer.
We summarize results from an investigation of the spatiotemporal distribution of NOx storage and intermediate gas species in determining the performance of a fully formulated, Ba-based, lean NOx trap catalyst under lean/rich cycling conditions.
On the basis of this model, the effects of canyon geometry on the distribution of NOx and CO from traffic emissions were studied over the center of Beijing.
The model predicts the time evolution of concentration of CO, NOx, HC, soot size distribution, CO2, H2O, SO2, NO, NO2, HONO, HNO3, SO3, H2SO4, O2, H, H2, O, OH, HO2, H2O2, and some HC species in the combustor and turbine.
We propose that the observed evolution of N2O selectivity with sulfation can be explained by changes in the spatiotemporal distribution of NOx storage resulting in either increased or decreased number of precious-metal sites surrounded by nitrates.
Experiments were carried out to investigate the appearance, temperature distribution, and NOx emission index of two inverse diffusion flames, one with circumferentially arranged ports (CAPs) and the other with co-axial (CoA) jets, both burning LPG with 70% butane and 30% propane.
The distribution of NOX by traffic intensity, is displayed in Figure 2.
