Abstract:
A method of controlling a boiler in which control is based on information from a control Matrix applicable to the specific operating parameters of said boiler comprising:(i) providing at least one fluorometer, one or more analytical devices and a controller; (ii) programming said at least one fluorometer and controller using planning information from a control Matrix for boilers being treated with treatment programs selected from the group consisting of: (a) Polymer Based All-in-One Product; (b) Residual Phosphate Polymer Product with Scavenger and Condensate Corrosion Inhibitor Fed Separately; (c) pH/Phosphate Product with Polymer, Scavenger, and Condensate Corrosion Inhibitor Fed Separately; (d) All-Polymer Product with Separate Scavenger and Condensate Corrosion Inhibitor Fed Separately; and (e) pH/Phosphate Polymer Product with Scavenger and Condensate Corrosion Inhibitor Fed Separately; wherein, in each of these treatment programs the Scavenger is selected from the group of oxygen scavengers consisting of Gallic Acid, Hydroquinone, Propyl gallate, 3,4-dihydroxybenzhydrazide, 2-hydroxybenzhydrazide, 4-hydroxybenzhydrazide and salicylal carbohydrazone; (iii) using said at least one fluorometer and said one or more analytical devices to determine the status of system factors; (iv) determining the pattern of changes in the readings from step (iii) over time; (v) comparing the changes in readings in steps (iii) and (iv), with the patterns listed in the control Matrix to determine what corrective action(s) is recommended; and (vi) using said controller to automatically implement said corrective action(s).
