Abstract
An odorant addition device for adding odorant to fuel gas in a gas system that consumes the fuel gas, the device including: an addition unit for adding the odorant to fuel gas to be consumed by the gas system; an environmental condition detection unit for detecting in the gas system an environmental condition regarding diffusion of odorant in fuel gas; and an addition adjustment unit for adjusting mode of odorant addition by the addition unit based on the environmental condition detected by the environmental condition detection unit. In this way, it is possible to detect leakage of fuel gas more reliably and improve safety dramatically, in a gas system that consumes the fuel gas as fuel.
