      However, the CO 2 concentration of the exhaust gas discharged from the present coal firing power plants is low because the combustion air contains only about 21% of oxygen and the remaining 79% mostly in the form of nitrogen is discharged as exhaust gas. The recovery of CO 2 from this flue gas …

      CO (carbon monoxide) What it is: CO is the result of incomplete combustion. The goal of burner/boiler design is to achieve complete combustion in order to release all of the energy available in the fuel. If some carbon molecules cannot find some oxygen molecules, they will partially convert to CO (carbon monoxide) rather than CO2 (carbon dioxide).

      Reduced emissions of CO2, NOx, and SO2 from U.S. power

      For coal, the average decreases in NOx (72%) and SO 2 (71%) emission intensities were steady but important, because coal power plants emit the majority of NOx and SO 2 associated with electric power generation. The NOx emission intensities for natural gas power plants with combined cycle decreased rapidly between 1997 and 2012.

      Selective non-catalytic reduction involves the injection of a NOx reducing agent, such as ammonia or urea, into the boiler exhaust gases at a temperature of approximately 1400-1600°F. The ammonia or urea breaks down the NOx in the exhaust gases into water and atmospheric nitrogen. Selective non-catalytic reduction reduces NOx up to 70%.

      The most common heat transfer method for coal-fired boilers is the watertube method in which the hot combustion gases contact the outside of the heat transfer tubes, while the boiler water and steam are contained within the tubes. Coal-fired watertube boilers include pulverized coal, cyclone, stoker, fluidized bed, and handfed units.
