Greater operating safety One problem with conventional boiler control systems has been the speed with which they detect problems and either take corrective action or report it to operators. In many cases, operators must intervene and correct the problem or eliminate safety hazards. Microprocessor-based systems eliminate the delay between detection and correction, and they can be programmed to take specific actions in the event of hazardous conditions, eliminating the need for operator intervention. They can even be programmed to notify remote personnel the moment problems develop. Even tasks such as starting a boiler can be made safer.
Operators typically estimate system-purge requirements.
By monitoring conditions within the boiler, the control system can determine the purge requirements for the boiler and automatically implement them along with the automated startup sequence. Reduced emissions One motivating factor behind the development of microprocessor-based controls is the push to limit boiler emissions. To meet these new standards, manufacturers updated boiler designs to include the use of flue gas recirculators and low-NOx cones on burners. But microprocessor-control systems have been one of the most effective means of limiting emissions. By constantly monitoring flue gases, the systems can quickly detect and correct operations to bring the boiler in compliance with the stricter standards.
