The invention provides an intelligent fuel system which comprises a digital coal field, an intelligent stacking material-fetching module and an intelligent collecting module, wherein the digital coal field adopts a 4D technique for showing the coal field information; the intelligent stacking material-fetching module is used for reasonably arranging the layout of the coal field and providing the optimal coal staking/fetching scheme; the intelligent collecting module is used for showing the production flow of the hardware equipment. The intelligent fuel system can help a power plant to completely eradicate all the human intervention or error factors and links in the whole process from the fuel entering the plant to the fuel entering into the furnace. Meanwhile, through the intelligent equipment, analysis tools, intelligent experts and knowledge base method, the fuel management becomes a powerful tool for bringing the sustainable economic benefit to the power plant.
