Heavy industrial facilities sometimes are required to meet regulations that involve more than NOx emissions and result in more complex systems and installations. The case studies here examine customer applications and key challenges.

Retrofit of dual fuel power generating station to meet NOx and CO emissions
The Saguaro Power Company is a subsidiary of NRG Energy, Inc. that operates a power generating station in Henderson, Nevada and provides electricity to the surrounding Las Vegas Area. The company was using an auxiliary Volcano O-Type Watertube Boiler with dual fuel capability to burn natural gas or a combination of natural gas and hydrogen fuels at 249 million BTU per hour. The auxiliary boiler keeps the steam system in a hot standby mode to quickly bring the power plant back online if the main system goes down.
New emission regulations imposed by the Clark County Air District, required reducing the level of NOx emissions to 12 ppm and the CO stack emissions to less than 1 ppm and would require Saguaro Power Company to make changes to their existing equipment. While Saguaro Power Company was faced with the challenge of meeting these tight emission requirements, they were also concerned with minimizing any loss in boiler capacity. Read more
