[0002] Coal slurry is a mixture of coal and water, also known as water-coal slurry. It is a low-pollution, high-efficiency, pipeline-transportable coal-based fluid fuel that replaces oil and is obtained through physical processing of about 65% coal, 34% water and 1% additives. It has changed the traditional way of burning coal and has shown huge environmental protection and energy-saving advantages. Especially in recent years, after adopting the technical route of waste resource utilization, the environmentally friendly water-coal slurry successfully developed can greatly improve the environmental protection benefits of water-coal slurry without increasing costs. Under the guarantee of my country's abundant coal resources, water-coal slurry has also become the most basic and economical clean energy to replace oil, gas and other energy sources.
