“…Taking advantage of CFD numerical simulation, Lancua et al studied the effects of using fuel gas and adding steam on NOx reduction in industrial burners with non-premixed flames [86]. The simulation tool ANSYS Fluent (ANSYS tutorial, 2015) was used to conduct a CFD analysis on a 300 kW swirlstabilized combustion chamber.…”

Effects of steam addition and/or injection on the combustion characteristics: A review

Due to increasing global energy demand and the fact that a major source of the required energy is generated from fossil fuels, the combustion process has turned into a topic of interest in converting fossil fuels to energy. An ideal combustion system is one that can combine high engine efficiency with low fuel consumption and low emissions. Increasing humidity is a technique used by researchers for influencing the combustion process. The present study aims to review previously conducted researches in this regard. Based on viewpoints of these researches, the reviewed studies were categorized into four groups: (1) the case studies used; (2) the methodology applied; (3) the design guidelines considered; and (4) the performance parameters studied. It can be concluded from the reviewed articles that nitrogen oxide (NOx) reduction is the most significant advantage of increasing humidity in the combustion process, and has led to the widespread use of this method. The other studied emissions either remained constant or their respective increases were negligible.

Abstract: Adequate supply of oxygen is essential for the complete combustion of fuel in the furnace of a boiler and defective duct design may cause serious loss in the boiler efficiency due to incomplete combustion. In boiler there is a system which controls the air flow rate reaching to the furnace. FD fan helps to build the pressure and force the air to pass through the duct and wind box. In wind box, this air will be sent to the furnace for helping combustion process. The main objective of this work was to simulate the flow of air from blower to the inlet of a wind box through rectangular split duct to see whether it could provide improved flow conditions and to see whether there was equal mass flow rate of air through both the legs of a split duct. The purpose of providing a split duct was to eliminate one blower which would otherwise be required for two separate ducts arrangement. A 3D model using CFD was prepared to capture the changes in the mass flow distribution in the duct at two different outlets. Through this analysis, it was found that the mass flow rates of air through the two legs of the split duct were not equal. The damping needs to be provided for the duct having longer length in order to have equal mass flow rate of air through both the legs of the duct.

“…This should include calculating and specifying the correlation, which can be useful to predict and extrapolate according to the existing data. Some of these correlations were involved in the CFD codes [1][2][3][4][5], but none of these relations gave a full explanation of combustion limits and the effect of parametric variations. Premixed combustion leads to low emissions [6][7][8][9][10] and more complicated relationships due to the influence of low fuel composition [11,12].…”

The most crucial phenomenon limiting gas turbine burner operation is the flashback and blowoff of flame in the combustor during gas turbine operation. In order to avoid this undesirable phenomenon, it is necessary to predict the operational map area of the gas turbine burner. Pure methane has been taken as fuel in this analysis, which attempts to construct a design map with two swirl numbers, 1.2 and 1.5. Different configurations for the outlet of the burner ranged from open flame with a normal nozzle, to cylindrical and conical confinements. The operation map area represents the allowance area of the burner when choosing the equivalence ratio and specified total mass flow rate. The results show that the workable area of the burner increases with the cylindrical and conical confinements, but shows no real difference between the two swirl numbers.
