BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating medium filling apparatus, and more particularly, to a moving heating medium filling apparatus for an explosion-proof facility that can be used in an explosion-proof area where a separate electric facility is difficult to use.

Large-scale power plants such as firepower, nuclear power, and hydroelectric power for current electricity production have advantages in terms of economies of scale, but they generate large amounts of greenhouse gas and are distant from consumers, resulting in transmission loss, and power transmission and substation facilities, And there are social and environmental negative factors.

Accordingly, in recent years, there is a need to develop various renewable energy such as solar light, micro gas turbine, and gas engine. In particular, biogas has been attracting attention in terms of utilization of waste resources, and many technologies and researches are being conducted in domestic and overseas for the utilization of biogas.

As a part of this research, there has been a progress in the development of a power generation system that applies biogas produced from household garbage or livestock manure to a gas engine in Korea.
