Two-stage combustion of plain and N doped oil

摘要: Number 2 fuel oil and doped with pyridine were burned in a well insulated two-stage combustion apparatus to investigate NO emissions reduction using rich-lean nearly adiabatic systems. The measured for baseline condition without secondary air addition these data compared the from two flowrates. For plain fuel, many of trends followed thermal arguments; however, second chemical formation mechanism was important first stage equivalence ratios greater than about 1.3. Burned gas composition measurements at exit showed that HCN NH 3 formed rich No. oil-air flames subsequent oxidation species lean contributed significantly emissions. When N burned, above phenomena limited minimum yield about. 20.
