Description Paper from the AFRC 2015 conference titled Flameless Heater Performance Two Years of Operation
Abstract The flameless crude heater designed by Great Southern Flameless (GSF) has; been operating continuously since March 15, 2013. During this 2 year run length (2.5 years by the time this paper is presented), GSF has spent many hours collecting and analyzing performance data. The; conclusions of this analysis will be presented in the GSF paper with documentation to support the conclusions.; What is certain is that traditional rules of thumb for designing conventional refinery heaters must be rewritten for flameless heaters.; We will cover in detail the following:; 1) NOx emissions equal to or lower than NOx emissions with traditional; combustion plus an SCR system.; 2) Equalization of peak to average radiant flux rates. API 530 ratios do not; apply to flameless heaters with double fired radiant coils.; 3) Tangential firing with associated significant increase in radiant section flue; gas mass circulation. 4) Elimination of any possibility for hot flue gas or flame impingement on the radiant process coil.; 5) Significant increase in run length and coil life by eliminating hot flue gas or flame impingement.; 6) Significant reduction in the overall heater size.; 7) Significant reduction in the process coil surface area.; 8) Significant improvement in traditional radiant section efficiencies.; 9) Significant shift in duty load from the convection section to the radiant section.; 10) Elimination of the requirement for filter/coalescer.; 11) Improved safety and reliability (availability) when compared to traditional combustion with varying refinery fuel gas composition.; 12) Scale up to any heater size while maintaining symmetry of combustion and heat flux to the double fired coil from the bottom to the top of the radiant section.; 13) Significant reduction in price when compared to a traditional double fired heater with air preheat system.; 14) Ever greater reduction in price when compared to a traditional double fired heater with air preheat and SCR system. Great Southern Flameless has presented to the AFRC and IFRF numerous papers since 2009 detailing the projected and actual NOx reduction associated with GSF flameless combustion. This paper will document the significant improvement in all other areas of heater performance, operation and pricing.
