Numerical Analysis and Experimental Validation of a Mono-block Natural Gas Burner

Abstract

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 was 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 emission of NOx 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.

Mono-Blok Tipte Bir Doğal Gaz Yakıcının Sayısal Analizi ve Deneysel

Abstract

Fosil 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 NOx 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 ölçe imkanları ile elde edilen verilerle doğrulanmıştır.
