Аннотация
The slagging rate in high-temperature zones and the furnace exhaust temperature in boilers firing high-ash coals increase with the ash content of coal. However, the slagging situation in pulverized-coal-fired boilers often improves with increase in the ash content of coal. This is because of the different effects of increase in the ash content on the slagging in different boiler zones and for different types of coal ash. The ash content affects the temperature of flue gas and the slagging properties; the effect of these factors can be either of the same or of opposite signs.
