Boiler Ash

Boiler ash refers to the final product formed after certain physical and chemical changes under the action of high temperature caused by the combustion of minerals in coal in the furnace. Because ash and slag in boiler will cause soiling, slagging, corrosion and heating surface wear and other problems, affecting the normal operation of the boiler, ash and slag must be effectively and timely removed. Part of the ash and slag is discharged by the slag hopper behind the grate of the layer combustion furnace, the cold ash hopper under the furnace of the pulverized coal furnace, or the slag outlet and slag well at the bottom of the liquid slag discharge furnace. The slag needs to be transported to the slag field (or ash pond) by the boiler slagging device, which is called slagging. Timely transportation and treatment of high temperature slag is a necessary step for safe operation of boiler.
