An ash pan is a flat, shallow container designed to collect and hold ash produced by the burning of fuel, such as wood, coal, or pellets, in a fireplace, wood stove, or furnace. Typically made of heat-resistant materials like steel or cast iron, the ash pan sits beneath the fire grate or inside the lower compartment of a stove or furnace, allowing ashes to fall into it as the fuel burns. Its purpose is to make ash removal easier, providing a convenient way to dispose of the debris without creating a mess.
