摘要

Years ago, as a technical leader in the utilities group of a large company, I was sent to an industrial facility in the Southeast to test the combustion efficiency of two 120,000-PPH steam boilers as part of a plan to reduce stack emissions and bring the boilers into compliance with new stricter emissions requirements. During a preliminary inspection of the boilers and auxiliary systems, I noticed both of the 100-hp boiler feedwater pumps were running. That was not normal. The boilers were installed as a 100-percent-redundant system. The steam load averaged 70,000 to 90,000 PPH from summer to winter. Generally, one boiler was to be in service and the other in standby mode using a continuous-blowdown heat-recovery concept to keep it warm at line pressure. I knew from visiting the facility previously the boiler feedwater pumps also were intended to be 100-percent redundant. With a steam load of 90,000 PPH, there was no good reason for two pumps to be operating. I went to the control room to further review the distributed-control-system data and to talk to the utilities crew.
