This invention relates to the field of fuel technology, specifically to a method for preparing a novel coal-based water composite fuel. The method includes: preparing an oil phase; preparing a mixed emulsion; and preparing the coal-based water composite fuel. This invention obtains a coal-based water composite fuel by mixing coal-based liquid wax No. 2 with a compound emulsifier, then emulsifying it with water, and finally mixing and maturing it with a coal-saving combustion aid. On the one hand, this invention solves the problems of traditional fossil fuels, such as reliance on petroleum resources, high sulfur and nitrogen impurity content, and excessive pollutant emissions during combustion. It also avoids the limitations of biomass fuels, such as low calorific value and easy coking, and synthetic fuels, such as difficult storage and transportation and high costs. On the other hand, it solves the problems of mediocre ignition performance and difficulty in controlling combustion temperature when coal-based liquid wax is directly burned, failing to utilize the "micro-explosion effect" to improve combustion efficiency, thus fully releasing the fuel potential of coal-based raw materials.
