WIPO Patent Application WO/2020/149584
Kind Code:
A1
Abstract:
The present invention pertains to a multi-functional foam concentrate-type agent for inhibiting spontaneous ignition of soft coal, wherein the agent can: inhibit spontaneous ignition of soft coal and prevent spattering of soft coal, thereby preventing problems due to spontaneous ignition, such as a power plant malfunction, the wasting of soft coal, and the generation of foul odors; enable the operation of an economical, safe, and eco-friendly soft-coal power plant using inexpensive soft coal; and improve the pour point of soft coal so that the soft coal can be used even at -20°C. The present invention is characterized in that: a spontaneous ignition-inhibiting agent is prepared in the form of a water-soluble foam concentrate by using an antioxidant, an agent for inhibiting volatile activation, and an emulsifier compound; the spontaneous ignition-inhibiting agent prepared in the form of a water-soluble foam concentrate is mixed with water and air; and the resultant mixture is sprayed and applied as a foam onto soft coal.
