This paper deals with the combustion characteristics of flue gas in infared mobile heaters. The experimental work has been performed to obtain the concentration levels and combustion characteristics of flue gas with varying chamber size and room temperature. The experimental results showed that oxygen depletion sensor device was operated at the oxygen concentration level of $18.3\%$ for all the chamber size. The combustion characteristics of oxygen and carbon dioxide show a linearity After 10 minutes the combustion property of carbon monoxide occurs at random without a level of oxygen and carbon dioxide in closed space of the heater. In these results, it is very important to prevent incomplete combustion through a sufficient ventilation, and accident prevention with a reduction of the oxygen and diffusion of toxic carbon monoxide.
