摘要
针对国电谏壁发电厂8号机组1 025 t/h锅炉引风系统风机技术改造,基于现场试验和运行数据分析了改造的必要性,通过2种技术方案的比较,确定了采用以引风机为基础取代增压风机二合一的改造方案,并利用数据计算说明拆除增压风机和保留原引风机能够满足实际运行的各种工况要求。该方案实施后,机组满负荷运行时厂用电率下降0.2%,节能效果显著。
Focusing on the technical retrofit implemented on the induced draft fan system of the 1 025 t/h boiler of NO. 8 unit in Jianbi Power Generation Company, analysis on the field test results and operating data is performed. In this paper, through comprising two proposed technical schemes, it is finally determined that the scheme employing the induced draft fan to replace the booster fan is accepted. The obtained test data show that this proposal can meet the practical requirements. It is also found that, after performing this retrofit, the station service power consumption rate is reduced by 0.2 %.
