I. Text Description Click here to view the details of the plan.
In the center of boiler furnace, the central temperature of combustion flame is between 1500~ 1700℃. At such a high temperature, most ash in fuel melts into liquid or is in a softened state. Because the water wall absorbs heat, the closer to the water wall, the lower the temperature from the center of the combustion flame. In general, with the decrease of temperature, ash will change from liquid to softened state and then to solid state. If the ash is still in a softened state and contacts the heating surface, it will be bonded to the heating surface due to cooling, forming coking.
