Experts: Warfare Between Coal and Gas Is Nonexistent

Markets may currently favor natural gas, but coal, which has been diminished for “good reason,” will likely have a significant place as a reliable fuel for power generation, a diverse panel of U.S. coal experts—including a generator, a supplier, and a market analyst—suggested at CERAWeek by IHS Markit in Houston on March 7. Coal lost […]

Test Your Knowledge: Boiler Chemical Cleaning

Most engineers and operators know (or should know) that boiler tubes containing deposits create long-term reliability problems for the boiler. Long-term overheating of the metal will result from prolonged operation with heavy tube deposits. The tubes will first bulge and then fail. Because the deposits tend to be widespread, this generally means that large sections of […]

Public Service Co. of New Mexico (PNM) closed Unit 2 and 3 of the four-unit San Juan Generating Station (SJGS) near Farmington, New Mexico, in December 2017. Unit 2 came online when the plant opened in 1973 and is the oldest unit at San Juan. Unit 3 began operation in 1979. The shutdown of these two units will result in the reduction of energy generation of approximately 836 MW. PNM plans to replace the loss in generation with a diverse mix of increased renewable energy, existing nuclear power, natural gas generation, and increased power capacity from Unit 4.
