Abstract : From time immemorial, there have been 3E problems of energy, economy and environment. In particular, problems
of energy and environment become increasingly serious after the industrial revolution. The demand for gas as an ecofriendly
energy source is also increasing. With the demand, the installation and the use of gas boilers have also increased,
so the damage to human life by the waste gas (CO and CO2) continues increasing every year. Hence, the aim
of this study was to investigate the concentration of CO (Carbon Monoxide) by the length and the variation of the bent
tube of the exhaust pipe by installing a boiler with the same method as a household boiler and to discover the harm to
humans. For the effect of the length, the allowable concentration of CO is 50ppm, and the 3m of the once bent tube
starts exceeding the allowable concentration of CO after 5 minutes, and the 4m and 5m starts exceeding after 3 minutes.
In addition, the 1m of three times bent tube starts exceeding the allowable concentration of CO after 3 minutes.
