Parametric Study of Emissions from Low Calorific Value Syngas Combustion, with Variation of Fuel Distribution, in a Prototype Three Sector Burner
(2011) ASME 2011 Turbo Expo: Turbine Technical Conference and Exposition- Abstract
- The emission composition is measured for a prototype burner
while varying the equivalence ratio in discrete portions of the
burner. The burner is a three sector system, consisting of a
separate igniter, pilot/stabilizer and main burner. The design
allows for discrete control of equivalence ratio in each of the
three sectors. The ignition sector, designated RPL (Rich-
Pilot-Lean), operates from rich to lean equivalence values,
and serves to ignite the pilot sector, which, in turn, stabilizes
the main combustion sector. All three burner sections are
premixed. The burner is operated at atmospheric pressure
with inlet flows heated to 650 K (±8 K). Tests... (More) - The emission composition is measured for a prototype burner

premixed. The burner is operated at atmospheric pressure
with inlet flows heated to 650 K (±8 K). Tests were performed
for three gases: methane, a model syngas (10% CH4,
22.5% CO, 67.5% H2), and dilute syngas. The dilute gas
includes sufficient nitrogen to lower the heating value to 15
MJ/m3. The model syngas and diluted syngas are
representative of fuels produced by gasification process. The
burner emissions, specifically, CO, CO2, O2 and NOx, are
measured while holding the RPL equivalence value constant
and varying the equivalence ratio of the pilot and main
sectors. The equivalence ratios for pilot and main sectors are
chosen such that the total burner equivalence ratios remain
constant during a test sequence. The target total equivalence
ratio for each gas is chosen such that all experiments should
have the same flame temperature. (Less)
