DeltaV Distributed Control System Product Data Sheet September 2015 Smartprocess™ Heater Get maximum value from your heaters using Emerson’s Smart Porcess ™ Heater solution  Extend run-lengths by balancing pass outlet  Increase heater capacity while operating temperatures to prevent hot spots and excess safely, efficiently, and dependably coking  Reduce energy cost by minimizing excess air and optimizing fuel usage  Lower stack emissions by promoting complete combustion and maintaining optimal excess air  Improve outlet temperature control by automatically compensating for changes in fuel composition, charge rate, and feed temperature DeltaV Distributed Control System Product Data Sheet September 2015 Introduction Advanced Regulatory Control Scheme The primary function of the advanced regulatory control Fired heaters are a primary source of heat input to many strategy is to provide robust control of the heater outlet refining and petrochemical processes. The goal of these temperature while maintaining sufficient air for proper heaters is to raise the temperature of a given process stream combustion of the fuel. The combined coil outlet up to a target for use in reactors, distillation columns and oil temperature controller is used to set a master fuel demand fractionators. In many sites, fired heaters use a fuel str
