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

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 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)
