ABSTRACT:
There is a process for operating a utility boiler. The process has the following steps: a) continuously adding one or more slag control agents, one or more oxygen-generating agents, and a fuel oil to a furnace of the utility boiler; b) providing air to the furnace; c) burning the fuel oil to generate heat and an exhaust gas; d) periodically or continuously varying the dosage rates of the one or more slag control agents and/or the one or more oxygen-generating agents to maintain to substantially maintain one or more emissions variables in the exhaust gas within pre-determined limits. There is also a method for reducing emissions from a utility boiler and a method for reducing slag deposits within a utility boiler.
