A Measurement of Intermediate Vector Boson Production in 1.8 TeV pp Collisions

The cross section for the production and subsequent decay to electron and neutrino of the W intermediate vector boson has been measured in 1.8 TeV /bar p/p collisions at the Collider Detector at Fermilab. An analysis of events with missing transverse energy greater than 25 GeV and an electron of transverse energy greater than 15 GeV from a data sample of 25nb/sup /minus/1/ gives sigma/center dot/B = 2.57 +- 0.56 +- 0.46nb, in agreement with theoretical predictions. 10 refs., 4 figs.

Nitrogen oxide abatement by distributed fuel addition (open access)

Nitrogen oxide abatement by distributed fuel addition

This research is directed towards the development of engineering guidelines that define the application of distributed fuel addition as a technique for NOx abatement. It is expected that multiple fuel and air addition in the post-flame of a combustion process will increase free radical concentrations which destroy nitrogenous species and thus help them decay toward their equilibrium concentrations, which can be very low in that region of the combustor. Screening experiments were conducted on a laboratory scale downfired combustor. The objective was to compare NOx emissions arising from various combustion configurations, including fuel and/or air staging. Although the primary focus of this research is on NO control, a secondary effort was directed towards the measurement of N2O emissions from various coal combustion processes. N2O has been identified as a trace gas responsible for stratospheric ozone depletion, and has been hypothesized to arise from combustion processes, in amounts roughly proportional to NO emissions. Results presented in this report showed that the ratio N2O/NO was far from constant. The introduction of secondary air into a combustion process was accompanied an increase in N2O emissions. The measured N2O was always less than 10 ppm even under the most favorable combustion conditions. Reburning with …

Nitrogen oxide abatement by distributed fuel addition. Quarterly report No. 3, February 1, 1988--April 30, 1988

This research is directed towards the development of engineering guidelines that define the application of distributed fuel addition as a technique for NO{sub x} abatement. It is expected that multiple fuel and air addition in the post-flame of a combustion process will increase free radical concentrations which destroy nitrogenous species and thus help them decay toward their equilibrium concentrations, which can be very low in that region of the combustor. Screening experiments were conducted on a laboratory scale downfired combustor. The objective was to compare NO{sub x} emissions arising from various combustion configurations, including fuel and/or air staging. Although the primary focus of this research is on NO control, a secondary effort was directed towards the measurement of N{sub 2}O emissions from various coal combustion processes. N{sub 2}O has been identified as a trace gas responsible for stratospheric ozone depletion, and has been hypothesized to arise from combustion processes, in amounts roughly proportional to NO emissions. Results presented in this report showed that the ratio N{sub 2}O/NO was far from constant.
