Super Boiler Technology

The Super Boiler is the culmination of more than seven years of DOE-sponsored research and development by the Gas Technology Institute, Des Plaines, IL and its partner, Cleaver-Brooks, Milwaukee, WI. It is supported by many environmental and energy saving interest groups.

In July, 2006, the Gas Technology Institute and Cleaver-Brooks installed a 300 hp high-pressure steam Super Boiler that has been running 24 hours a day, five days a week with excellent results. After more than 6,000 hours of operation, fuel-to-steam efficiency has been consistently in the 93% to 94% range, and NOx levels have been less than 9 ppm. Annual gas savings have averaged nearly 13%.

Cleaver Brook hopes to be able to replace 25% of aged operating boilers with the new technology. “(This technology) can be applied to existing boilers,” Dan Willems, vice president product engineering, Cleaver-Brooks says. “You can get very close to 90% efficiency.
