The slag extractor steel chain is a key component in the transportation of slag from the furnace or the bottom of the boiler to the designated disposal area. In coal-fired power plants, a significant quantity of slag is produced during the combustion process of coal. Its continuous operation ensures the smooth operation of the boiler and prevents the accumulation of slag, which could otherwise affect combustion efficiency and the normal operation of the equipment.
