Flue gas sampling challenges in oxygen-fuel combustion processes

摘要

There are increasing pressures on industrial producers to reduce pollutant emissions from their processes. These are mostly a result of the Clean Air Act Amendments. This paper specifically deals with NO and CO emission from combustion processes. These emissions have been monitored for many years from utility boilers in the power industry. However, they have only recently become of interest in high temperature combustion applications, because of the new environmental regulations. Typical industries include glass and metals production, where furnace temperatures are at about 2400 deg F. This paper discusses potential problems one may encounter in attempting to measure emission levels from high temperature oxygen-fuel combustion processes.
