Carbon monoxide emissions were less than 50 ppm. I don't know if anybody else has independent emissions test data documenting NOx ppms in the teens with boilers of this size operating from low fire through full capacity. Bambeck Systems, Inc., Santa Ana, Calif., provided a fully integrated combustion control system to operate the boilers. The relay module's nonvolatile memory stores historical information, such as the last six faults and cycle and hour of occurrence. The keyboard display module also provides extensive diagnostic and historical information.
Information is displayed in plain English as well as codes.
That's one reason Paul Koceski, central plant control specialist for CalTech, opted for the Honeywell system. CalTech also uses Honeywell's first-out expanded annunciator, which monitors 21 additional safety limits and control points. The expanded annunciator also shows the real-time status of the limits and controls, and expands fault information with more than 80 diagnostic messages. Koceski said the Honeywell control system saves CalTech operators time and work while improving safety. It makes it so easy to troubleshoot.
