| Abstract: | Some problems are found in direct firing pulverizing system of a power plant, such as lack of mill capacity and large amount of coal stone. Through analysis of these problems, wind ring of coal mill is transformed, airflow speed of coal mill export duct is balanced, pulverized coal fineness of pulverized coal is optimized. After these measures, mill capacity is increased, coal stone coal is reduced, combustion and operation of boiler is perfected, unit economy is improved. |
