Energy-saving and environment-friendly boiler capable of improving combustion efficiency

The invention relates to the related technical field of boiler equipment, and discloses an energy-saving and environment-friendly boiler capable of improving combustion efficiency, which comprises a coal furnace barrel body, a heat preservation tile body layer is arranged in the coal furnace barrel body, a coal combustion cavity is arranged in the heat preservation tile body layer, and honeycomb briquette fuel is stacked in the coal combustion cavity. The lower side of the coal combustion cavity communicates with a coal ash storage cavity, and a combustion auxiliary mechanism is installed in the coal ash storage cavity in a liftable mode. According to the energy-saving and environment-friendly boiler capable of improving the combustion efficiency, a combustion-supporting structure and a unique air duct structure are applied to the interior of the barrel, so that the effective combustion efficiency of honeycomb briquettes can be greatly improved, and the problem that carbon dioxide is generated due to insuffic
