Basket ash is a term commonly used in the realm of coal power plants. It refers to the bottom ash that collects in the furnace of the power plant's boiler. This type of ash has a different consistency than fly ash, which is carried up and out of the boiler through exhaust stacks. Synonyms for basket ash include coal ash, clinker ash, and furnace bottom ash. These terms all refer to the same product, which is the ash that accumulates at the bottom of the furnace. Despite the varying names, the properties, and utilization of the product is the same, making it an essential byproduct of the power production process.
