Energy-saving boiler capable of reducing fire coal consumption rate

The invention belongs to the technical field of boiler combustion, and particularly relates to an energy-saving boiler capable of reducing fire coal consumption rate, which comprises a heat insulation shell, an adaptive clamping cover is fixedly connected to the top end of the heat insulation shell, a water supply device is slidably connected to the axis of an inner cavity of the adaptive clamping cover, and a storage box is fixedly connected to the lower end of the heat insulation shell. A material partition plate is arranged in an inner cavity of the heat insulation shell. When the boiler is used for heating water in the fixed base, the storage box transports refined coal to the upper portion of the partition plate through the threaded push rod for combustion, and due to the fact that the coal can be crushed and separated when extruded by the flat laying rotating plate and pushed by the threaded push rod, the coal can be combusted, and the coal can be combusted; therefore, the coal conveyed to the upper por
