The Effect of Temperature on the Emissions of Shale Gas Combustion in USA

Öz

The turbulent, non-adiabatic, and non-premixed combustion of shale gas and air in a cylindrical combustor is computationally investigated under the effects of equivalence ratio, wall temperature, fuel and oxide inlet temperatures. The results indicate that the mass fractions of NO come to the maximum values at 0.97, 1.03, and 1.03 equivalence ratios for Fayetteville, New Albany, and Haynesville. The rising equivalence ratio raises CO emissions for all the shale gas. The rearing oxide inlet temperature increases NO mass fractions up to 290 K for Fayetteville and 308 K for New Albany and Haynesville. It also enhances CO emissions. The escalating fuel inlet temperature boosts NO mass fractions. However, it reduces CO emissions at all the shale gas combustion. The ascending wall temperature uplifts both NO and CO mass fractions.

ABD’de Kaya Gazı Yanmasının Emisyonları Üzerinde Sıcaklığın Etkisi

Öz

Silindirik bir yakıcıda kaya gazı ve havanın türbülanslı, adyabatik olmayan ve önkarışımsız yanması ekivalans oranı, duvar sıcaklığı, yakıt ve oksit giriş sıcaklıklarının etkileri altında hesaplamalı olarak incelenmiştir. Sonuçlar NO’in kütle kesitlerinin Fayetteville, New Albany ve Haynesville için 0.97, 1.03 ve 1.03 ekivalans oranlarında maksimum değerlerine ulaştığını göstermektedir. Artan ekivalans oranı tüm kaya gazları için CO emisyonlarını yükseltmektedir. Yükselen oksit giriş sıcaklığı Fayetteville için 290 K ve New Albany ve Haynesville için 308 K’e kadar NO kütle kesitlerini artırmaktadır. CO emisyonlarını da yükseltmektedir. Artan yakıt giriş sıcaklığı NO kütle kesitlerini artırmaktadır. Bununla birlikte, tüm kaya gazları yanmalarında CO emisyonlarını düşürmektedir. Artan duvar sıcaklığı hem NO hem de CO kütle kesitlerini yükseltmektedir.
