Oxygen Enriched Combustion System Performance Study

Show full item recordAbstract
The objective of this study is to identify
potential industrial applications for which oxygen
enriched combustion systems are technically,
environmentally and economically feasible and offer
significant energy savings and/or productivity
improvement, and then to verify the performance
of selected systems in research furnaces. Tests
of several commercial burner designs have been
conducted at scales of 1 x 10^6 Btu/hr and 10 x
10^6 Btu/hr. The burners represent both conventional
air fired designs and oxygen/fuel burners
designed primarily for very high oxygen levels.
The results of these tests indicate that over
50 percent fuel savings can be achieved with
oxygen enrichment compared to air under certain
conditions. The different burners demonstrated
distinct axial wall temperature distributions which
changed by varying degrees as the level of oxygen
enrichment was increased. NOx emissions increased
sharply as the level of oxygen enrichment was
increased for conventional air burners up to 35-50
percent oxygen. However, specially designed
oxygen/fuel burners showed very low NOx emissions
for 35 - 100 percent oxygen. The absolute levels
of the NOx emissions also depended on the furnace
temperature.
