ABSTRACT
Chemical technology has been implemented as a significant means of energy saving and environmental reduction of emissions in oil-fired steam generation. Applications include combustion improvement, slagging modifications, fouling prevention, corrosion inhibition and particulate emission control. Chemical technology offers savings in steam generation through: (a) elimination of equipment replacement; (b) reduction of fuel costs and (c) reduction of operating expenses at the same time that particulate and acidic stack emissions, referred to as “extreme air pollution,” can be achieved to meet current requirements of the regulatory agencies. The operating experience at a utility with a cold-end neutralizing additive to lower the acid dew point is detailed.
