Description Paper from the AFRC 2017 conference titled Field Measurements of Flame Scanners in a Gas-Fired Boiler under Controlled Operation Charges
Abstract Real-time monitoring of coal-fired utility boiler flames has been in active commercial implementation for at least two decades. One such system - Flame Doctor® - relies on numerical analysis and pattern matching of flickering dynamics as measured by visible-IR flame scanners installed on each burner. This diagnosis system can monitor up to hundreds of burners in large furnaces and allow operators to optimize the unit for combustion efficiency and emissions. Field experience has shown that significant improvements in emissions performance can be achieved with changes to just a small number of burners, and the ability to monitor all flames, especially where visual access is not possible, is of great utility for plant operation.; We have begun adapting the successful Flame Doctor paradigm to gas-fired furnaces and process heater systems. As a first step, we present here analysis of field data acquired from a six-burner gas-fired furnace firing natural gas. A portable Flame Doctor system monitored the output of custom visible-UV flame scanners, and the furnace operating parameters were varied through a series of controlled experiments. We show how the statistical changes in the furnace flame response show promise for a gas-fired flame-monitoring system which would be applicable from single-burner process heaters to large, multi-burner furnaces.
