“…The liquid-fueled ultra-high swirl flameless combustor was designed with the objective of simplifying the structural geometry of a liquid fueled flameless combustor and the overall combustion process to achieve flameless mode. It can be seen that most of the designs in previous works had complex geometries and were also quite miniscule compared to industrial scale [14]. Thus, a semi-industrial scale liquid fueled flameless combustor was designed using simple cylindrical geometry to minimize manufacturing cost and to prove that geometric structure has minimal effect on the success rate of achieving flameless mode.…”

This paper presents the experimental results of a simple cylindrical shaped, liquid fuelled flameless combustor which utilizes ultra-high swirl flow in the combustion process. 4 different swirl generator inlet configurations were tested in this work. Ethanol fuel were used during flameless mode. The experiments were conducted at equivalence ratio (F=1), with the flow rate of fuel set at 4.48*104 kg/s, and flow rate of air at 3.854*103 kg/s. The results revealed that by using all 12 tangential air inlets (swirl generator injectors), the swirl strength was reduced through evenly distributing the position of the injectors circumferentially. As a result, the combustor successfully suppressed the emission of NOx and CO to zero ppm for both gasses. It was also reported that flameless mode was established in all configurations, regardless of the swirl strength.

“…This also contributed into lower combustion operating temperature and peak temperature inside the combustion chamber. As a result, the cost of maintenance can be significantly reduced due to the increased machine lifetime in long term application [14].…”

“…Although the flow rate of fuel was observed to influence flame visualization and temperature distribution, the skewed swirl vane yielded the most enhanced highest flame shape and temperature profile when compared to twist and curved swirl vanes. In a study carried out by [21], a cylindrical single chamber flameless liquid fuel swirl based combustion reactor was proposed. This LFSB design utilizes maximum swirling effect and multiple air injection to increase fuel residence time as well as mixing time for achieving flameless mode.…”

Accurate monitoring and controlling of the temperature in the combustion chamber can raise the burner efficiency, combustion intensity, fuel consumption and reduce pollutant emission. However, except combustion is accurately monitored and controlled, high concentration of pollutant gases and products like carbon monoxide (CO) and soot can form in the combustion chamber. This paper compares the combustion thermal profiles in a liquid fuel swirl burner using developed straight edge and curve edge blade swirlers at (20, 30, 40, 50 and 60)° for 6, 8, 10 and 12 number of blades in order to optimize the temperature of the burner. Measurements were made in straight and curve blades liquid fuel swirl burner in order to study and compare the thermal characteristics of the straight and curve edge blades in optimizing the combustion dynamics. Similarly, measurements were made for burner without swirl generator and the combustion temperature assessed. Thermal profile was measured in the direction of flow via the six axial ports at distance ((d) =150, 350, 550, 750, 950 and 1150 mm) from the burner exit using Chromium-Zinc thermocouple. Results showed that the wavelength and oscillation of temperature decay in the same type of blade followed the same trend and the peak of combustion intensity is nearer the nozzle for curve edge blades than the straight edge blade. Six (6) blades performed best with the highest temperature in all the ports, while 12 blades gave the least performance. Findings further show that curve edge blade swirlers gave better performance than straight edge blade swirlers with highest temperature of (1065 and 1015) °C, respectively. Hence, it is recommended especially where high temperature and stability application is desirable
