Abstract
The mechanism of starting a fire from a kerosene fan heater by misusing of gasoline is similar to that from a wich-type kerosene heater. However, a combustion control device and many safety devices of a kerosene fan heater are different from those of a kerosene heater. Therefore, it is necessary to elucidate an outbreak of fire risk by these differences.
In this work, an outbreak of fire risk of a kerosene fan heater by misusing of gasoline was examined through combustion experiments. Then, we confirmed that the mechanism of starting a fire from a kerosene fan heater require fuel leakage as well as a kerosene heater. The difference of the structure of a kerosene fan heater influenced the outbreak of fire mechanism. And a flame sensor that is one of the safety devices was found to detect misusing of gasoline. Moreover, the GC analysis of each component of a burnt-out kerosene fan heater was found to be effective to prove misusing of gasoline.
