Publisher Summary. The oxygen/recycled flue gas (O 2 /RFG) combustion system is one of the candidates to recover CO 2 from pulverized-coal firing boiler. This chapter investigates the characteristics for NO x, SO 2, and CO 2 emission from the system through combustion tests in the 1.2 MWt test furnace. The amount of NO x emitted from the stack was much less than ordinary air …

Industrial, Commercial, and Institutional (ICI) Boilers .

Industrial boilers are used in all major industrial sectors but primarily by the paper products, chemical, food, and petroleum industries. EPA estimates that the heat input capacity for these boilers is typically between 10 and 250 MMBtu/hr. However, larger industrial boilers do exist and are similar to utility boilers.
