What are the factors that affect the accuracy of fuel-gas flame temperature and heat readings?
?
What will be an ideal response?
?The data available for fuel-gas flame characteristics are not gathered in a consistent manner. Temperature and heat, for example, are very basic physical facts about the flame of a specific gas. But even these facts can be misleading. The flame condition, such as neutral, oxidizing, or carbonizing (carburizing), and/or the purity of the gases being used will affect the temperature of the flame. The method by which the temperature is measured also affects its value. The highest potential temperature values are determined by chemical analysis and by the calculation of the theoretical energy released. However, no combustion is perfect, so this temperature is never attained. An infrared analysis or optical pyrometer of the flame gives the highest temperature in the flame. But this temperature is concentrated in a thin layer around the inner cone and is so small that it is not of practical use.?The optical pyrometer and the infrared analysis both give an accurate temperature reading, but where the temperature is measured makes a difference.
