Tropicana Las Vegas was in a desperate situation with their two large fire tube water boilers that service the majority of the casino resort property. These boilers were operating below 70% efficiency. The boilers were only 10 years old and were experiencing multiple boiler tube failures and burner damage each year costing hundreds of thousands of dollars in repairs and lost revenue due to hot water shortages to the guest rooms.
University Medical Center had a need to replace most of their heating and domestic water boilers. As part of an Energy Conservation Project developed by AMERESCO the total energy savings from all plant upgrades, which included lighting, controls, high-efficiency motors, VFDs, new boilers and pumps, made the boiler upgrades possible. Four of the old boilers had already failed and five others had burners needing replacement. CO emissions from 5 of the existing boilers tested were over 1500 ppm.
James Down Towers is a 220-unit four-story apartment building, which is part of the Southern Nevada Regional Housing Authority. The existing boilers were over 20 years old and had shown leakage and need of replacement. In addition, one of the two boilers was in extremely poor condition, which prompted an emergency replacement during the middle of winter, 2021.
The Department of Air Quality Management reviewed the operating permit at Centennial Hills Hospital, and it was determined that the existing burners could not satisfy the emission limits.
The re-designed Hoover Dam Lodge included the replacement of two old 1.7 mmbtuh atmospheric domestic water heating boilers with three .75 mmbtuh condensing units. This exceeded expectations and resulted in considerable savings.
