Waste-to-energy is an effective method of coal waste recovery and one of the possible solutions to the hydrocarbon depletion problem. The recovery of coal processing wastes and combustion of low-rank coal fuels involve technological challenges associated with long ignition delay, high toxic gas emissions, lower combustion zone temperature, and, hence, lower degree of combustion. To overcome these challenges, we propose a novel approach to intensify the combustion of coal slime and coal using hydrate gas. Hydrate contains methane and water. When heated, hydrate dissociates into water vapor and methane, which makes a promising gas–vapor mixture for energy generation. Using the research findings, we derived the effective conditions of hydrate regasification for the continuous supply of methane to the combustion chamber. The mathematical expressions formulated in this research relate the main characteristics of heat and mass transfer in the dissociation unit and in the combustion chamber. We also determined the regasification rates of gas hydrate exposed to electric heating in a system with a heat transfer fluid. A technological solution proposed on the basis of the research findings will increase the energy efficiency of coal processing waste recovery and reduce the anthropogenic emissions.
