Recovery boiler – Control functions An early paper divided the digital control systems for recovery boiler control into four groups. 1 This grouping also shows the main development stages of the computerised control for the recovery boilers in the pulp and paper industry. The first group performed only information tasks, such as reporting, alarming, and
