“…The SIMPLEC algorithm of pressure-velocity coupling is adopted to obtain the pressure field. Moreover, the turbulence model of SST k-x [18,19] is finally selected for its stability and ability to offer relatively high accuracy in cylindrical fields [20][21][22].…”

“…There are several studies in literature using CFD to examine the emission levels of burners having various capacities and the results are verified experimentally. Šarlej et al [8] focused on CFD computation of an experimental low -NO x burner with a two-stage natural gas burner for capacities between 0.5 MW and 1 MW. Several alternatives were introduced to minimize NO x emissions.…”

Fossil fuels are still one the major sources of the energy production. Fuels, utilized in the power generation, especially in industrial scale applications, are almost hydrocarbons in gaseous, liquid or solid phases. In combustion of gaseous fossil fuels, besides the several other emissions carbon monoxide and nitric oxide which are identified as the main suspects of the environmental pollution are produced.In this study, the flow field and the emission statistics of an industrial scale gas burner were investigated numerically. The burner and the assembled combustion chamber have been modelled using ANSYS-Fluent software. The standards for flue gas emissions of gas burners defined in TSE EN 676:2000 Class-3 have been taken into account. One of the most important emissions of NO x level given in that standard, limited to be less than 80 mg/kWh, has been initially computed for the existing burner and then for the modified burner designs. Both the velocity and temperature fields are calculated and represented in terms of contour plots. The emission results are collected at the exit of the combustion chamber and the chamber wall temperatures have been also computed. The numerical model results were validated with the available experimental measurements obtained from on-site test facilities. ÖzFosil yakıtlar halen enerji üretiminin en önemli ana kaynaklarıdır. Enerji üretiminde, özellikle endüstriyel ölçekte uygulamalarda kullanılan yakıtlar büyük oranda gaz, sıvı veya katı fazlarda bulunan hidrokarbonlardır. Gaz fazındaki fosil yakıtların yanmasında, diğer bazı emisyonların yanı sıra çevre kirliliğinin ana şüpheli olarak nitelendirilen karbon monoksit ve nitrik oksit de üretilmektedir.Bu çalışmada, endüstriyel ölçekte bir gaz yakıcısının akış alanı ve emisyon istatistikleri sayısal olarak incelenmiştir. Yakıcı ve buna bağlı yanma odası ANSYS-Fluent yazılımı kullanılarak modellenmiştir. Gaz yakıcılarının gaz emisyonları için tanımlanan TSE EN 676:2000 Class-3 standardı göz önünde bulundurulmuştur. Bu standartta yer alan en önemli salımlardan birisi olan NO x seviyesi, ki 80 mg/kWh'den az olacak şekilde sınırlandırılmıştır, öncelikle varolan sonrasında ise iyileştirilen yakıcı tasarımları için hesaplanmıştır. Hız ve sıcaklık alan değerleri hesaplanmış ve kontur grafikleri olarak çizdirilmiştir. Salım sonuçları yanma odası çıkışında toplanmıştır ve ayrıca yanma odası duvar sıcaklıkları hesaplanmıştır. Sayısal model sonuçları firma bünyesinde var olan deneysel ölçme imkanları ile elde edilen verilerle doğrulanmıştır.
