Zusammenfassung:The present invention relates to a multi-functional spontaneous ignition inhibitor in a form of a foam concentrate for bituminous coal for inhibiting spontaneous ignition of bituminous coal and at the same time preventing scattering, preventing problems such as power plant operation failure due to spontaneous ignition, bituminous coal waste, odor generation and the like, enabling an operation of bituminous coal power plant in an economical, safe, and eco-friendly way using low-cost bituminous coal, and improving a flow point so that the inhibitor can be used at minus 20 degrees Celsius. The present invention is to prepare a spontaneous ignition inhibitor in a form of a water-soluble foam concentrate using an antioxidant, a volatile activation inhibitor, and an emulsifier compound, and is to mix the spontaneous ignition inhibitor in a form of a water-soluble foam concentrate with water and air to disperse and apply the same on the bituminous coal in a form of foaming. 본 발명은 유연탄의 자연발화를 억제함과 동시에 비산을 방지할 수 있도록 하고, 이를 통해 자연발화로 인한 발전소 가동장애, 유연탄 낭비, 악취발생 등의 문제를 예방할 수 있도록 하며, 저렴한 유연탄 사용으로 경제적이고 안전하며 친환경적으로 유연탄발전소를 운영할 수 있도록 하고, 유동점을 개선하여 영하 20도에도 사용할 수 있도록 한 포원액 형태의 다기능성 유연탄용 자연발화억제제에 관한 것이다. 본 발명은 산화방지제, 휘발분활성화억제제, 유화제 화합물을 이용하여 수용성의 포원액 형태(Foam Concentrate)로 자연발화억제제를 조성하고, 수용성의 포원액 형태로 조성된 자연발화억제제를 물 및 공기와 혼합하여 포 형태(Foaming)로 유연탄에 분산 및 도포하는 것을 특징으로 한다.
