Performance Analyzing Test of a Pulverizing System |
| |
| Abstract: | Because of the high flow resistance of the coarse particle separator, the ball mill's intermediary bunker type pulverizing system of Guangzhou Power Plant's boiler No.1 has but a bad performance and poor profitability., Moreover the efficiency of the fine particle separator is also poor with tertiary air containing too much pulverized coal. Therefore, a retrofit was undertaken. The paper describes the coal conveying system's state before retrofit and in detail test results after retrofit and optimizing adjustment. |
