Planar Temperature in Flames: How You Can Measure It??Enurga
In order to ensure that the flames in the furnace are the right for the purpose, it’s important to conduct a thorough analysis of combustion. However, keep in mind that there are plenty of sub-products created by combustion such as temperature. And since temperature needs to be controlled, a proper analysis of combustion is very important for measuring the exact planar temperature in flames.
Another reason why analysis is important is that it helps you know the flame propagation modes such as positively and negatively stretched flames and planar flames, as well as their impacts on the equivalence ratio and flow rate. It also tells you about the effect of different parameters including the heating rate, channel aspect ratio, and divergence angle on the formation of planar flames.
But, how do you conduct combustion analysis?
Spectrometer, on the other hand, is the equipment that is used for combustion analysis. This device can be used for plenty of applications including:
- Gas concentration, soot volume and temperature fraction measurement in flames
- Flame impairment and solid surface studies
- Emission tomography
- Combustion research
- Measurements of flame spread, etc.
Additionally, a spectrometer can also be utilized for different industrial uses including measuring temperature and other components in gas turbine combustor, measuring the temperature of the turbine blade, monitoring the molten and hot metal process, etc.
How do spectrometers work?
Spectrometers basically have a window-mounted on the interface place that allows the radiation to enter the port of the device. The radiation is passed through a set of mirrors, and the pair of calcium fluoride prisms then scatters the radiation. The dispersed or scattered radiation falls on to PbSe array that furthermore changes the radiation into the current.
Besides, there is also a drive circuit that transforms the currents to voltages and extends and sends them to the data acquisition board. On the data acquisition board, there is an InfraSpec graphical user mounted on it that turn the voltages into spectral radiation to be analyzed and interpreted for understanding varying components as well as temperature in the flame.
You can find many good options of spectrometers that are available out there if you want to use the device for different applications. However, before choosing any random brand, make sure you research about it as there are many similar companies that offer solutions and devices for measuring the temperature as well as other elements in flame. Consider the price factor, workings and durability of the device, and ensure you choose the one that is best suited for your needs.
