300MW中储式W型火焰锅炉RB试验分析

Test Analysis of RB for 300 MW Indirect Coal W Flame Boiler

介绍了越南广宁电厂300 MW机组中储式W型火焰锅炉辅机故障快速减负荷(简称RB)试验的情况,针对中储式W型火焰锅炉的运行特点,采用了相应的控制策略,为机组长期、安全、稳定运行打下良好基础。对RB试验过程中出现的问题进行分析,并对控制回路参数及逻辑进行优化与改进,为同类机组进行RB试验提供了参考。

This paper introduces the indirect coal W Flame boiler Runback （Referred to as RB） function test of Quang Ninh Thermal Power Plant of Vietnam Phase II 2 x 300 MW Unit. Based on the operation characteristics of the indirect coal W Flame boiler, corre- sponding control strategy is used to lay a good foundation for a long-term, stable, safe operation. The problems appeared in the expeu- mental process are analyzed, optimizeing and improving the control loop parameters and logic, thus providing reference for the same type unit of RB test.
