Description Paper from the AFRC 2016 conference titled LSR Investigation on a Demonstration-Scale Lab Furnace
Abstract This is the fourth in a series of recent American Flame Research Committee (AFRC) papers related to the motivation, simulation technology, simulation results, and lab testing of the LSR (Large Scale Recirculation) concept for application to oilfield steam generators and boilers.; At the 2013 Kauai AFRC meeting, the first paper was given on the regulatory and combustion system progression that led to the need and ability for single digit-capable, Ultra Low NOx combustion. A second paper was given on the computational framework for analyzing such a system - the High Performance Computing ARCHES Large Eddy Simulation (HPC LES) tools developed between the Department of Energy and the University of Utah (UU), including a validation against field data collected on a full-scale, 62.5 MMBtu/h steam generator equipped with a Fives North American Combustion MagnaFlameTM GLE (FNAC GLE).; The third paper, given at the 2014 Houston AFRC meeting, introduced the LSR arrangement: a lean premix primary combustion zone with a secondary, flameless combustion zone created by secondary fuel diluted by externally-provided Flue Gas Recirculation (FGR); it also presented simulation results for LSR on a 62.5 MMBtu/h steam generator to be less than 5 ppm NOx.; This fourth paper, for the 2016 Kauai AFRC meeting, describes demonstration-scale testing of multiple configurations of a 13.3 MMBtu/h, LSR-based system on a water-cooled test furnace at FNAC. Parameters of interest to the LSR investigation include the FGR flow rate within the LSR, LSR injector quantity (and implicitly velocity), and LSR premixedness.; Results from this demonstration-scale testing indicate that LSR may be a viable approach for industrial-scale steam generator and boiler applications.
