“…Within a stovetop burner, the flame spreads rather rapidly, propagating around full rim within a second. However, it may start at an arbitrary point in time after turn-on due to specific environmental conditions [5]. Figure 2 presents visible and IR images of the ignition process in a gas-stove (produced by Mabe, a Mexican subsidiary of GE), initiated with an electrical spark.…”

For the last 15 years we have been studying initiation and propagation of rapidly evolving processes in IR and developing the instruments to capture the essential features of combustion phenomena. We present an IR optical experimental setup to capture two spectral images of the same scene. We apply this technique to flame analysis in the mid-IR to determine the combustion efficiency, as measured by the CO-gas production.

“…Thereby, a small improvement in combustion characteristics can provide a significant enhancement on the fuel economy and emission [4]. A considerable amount of literature has been established due to the importance of this topic [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18].…”

“…They reported that achieving 10 % efficiency improvement is possible using porous burner. In another research, Strojnik et al [16] presented the combustion evolution for gas burner. The visualization study enabled to implement a more effective and safe design of the electric spark sequence, fuel influx ducts, and the combustion chamber configuration.…”

Domestic cookers are common tools of house appliances in the world and they have significant share in global energy consumption. Therefore, a small amount of improvement in efficiency would result in a huge drop in total energy and resource activity. This study aims at presenting numerically the thermal efficiency of a domestic burner with crescent-shaped flame channels by changing the distance from the cooker to the burner head and the diameter of the burner. The energy efficiency parameter was evaluated analyzing temperature distribution along the bottom surface of the cooker and unburnt HC, CO and NO emissions. Simulations have been carried out with methane as fuel for three different diameter and distance parameters. The results showed that the temperature on the surface and the emission values of unburnt CO, NO and HC decreased with increasing the cooker diameter and distance parameter.

“…[8,9,10,11] We studied fire propagation for domestic and industrial applications, to assess its initiation and evolution, with a particular emphasis on safety considerations. [12,13] Studying a home burner both in visible and in IR, we observed, for example, that the spark plug functioned to heat the air around it, rather than to heat the fuel, in the initial incorporation of the device. This resulted in a dangerous accumulation of fuel.…”

We examine the propagation of the Yarnell Hill Fire in Arizona, June 28 --July 3, 2013 to assess the nature of its complexity. We identify the critical fire growth that starts about 35 hours after the fire initiation. In a time span of three hours, the fire area is doubled. Within the following four hours, the direction of fire turns by about 180 degrees. An hour later, a pyrocumulonimbus cloud is observed above the fire area. To monitor complex fires, we propose implementation of an IR instrument to scrutinize fire remotely for behaviors, such as vortices and rotation, arising from combustion events, terrain characteristics, and outside influences. We propose a small reconnaissance plane circling to the side and above the fire area to search for anomalies in fire propagation and atmosphere during the fire consolidation during the initial 45 hours. Ideally, the observing instrument would be sensitive in IR region at about 4.5 microns where carbon oxide emits and water transmits the radiation.
