NOVELTY - A food waste fuel comprises wastewater sludge, waste lime powder, waste coal, food waste and waste oil provided to feeder. The mixture is processed by a pellet molder (8), and a pellet arrangement machine (9) is arranged with a pellet. Driers (10-12) are utilized for drying the pellet, and fuel is supplied by a fuel tank (13) for combustion. Hot air is produced, and gas is generated in the driers. Drain water (16) ejected by a dust collection/purification unit (15) is purified and reused. Contaminant of the dust collection/purification unit is removed.    USE - Food waste fuel.    ADVANTAGE - The fuel enables preventing heat loss and air pollution.    DETAILED DESCRIPTION - A food waste fuel comprises wastewater sludge provided in a first feeder to be pulverized to size less than 1 mu m, a second feeder provided with waste lime to be pulverized to size less than 1 mu m, a third feeder provided with waste coal that is pulverized to size less than 1 mu m, a fourth feeder provided with food waste that is pulverized to size less than 1 mu m, a fifth feeder provided with waste oil, and a mixer is mixed with 4-6 weight% of tide, and a sixth feeder provided with (in wt%) wastewater sludge (10-15), waste lime powder (10-15), waste coal (30-35), food waste (25-35) and waste oil (5-10). The mixture is processed by a pellet molder, and a pellet arrangement machine is arranged with a pellet. Driers are utilized for drying the pellet, and fuel is supplied by a fuel tank for combustion. Hot air is produced, and gas is generated in the driers. Drain water ejected by a dust collection/purification unit is purified and reused. Contaminant of the dust collection/purification unit is removed. An INDEPENDENT CLAIM is also included for a food waste fuel resource system.
