4 Combustion of Fossil Fuels
The burning of fossil fuels is an abrupt reaction of fossil fuel chemical elements (C, S, H, N) with oxygen in the surrounding air. Of special concern is the NOx-emission from the burning of coal and fuel oils, especially the hazardous emissions from diesel fuel burning. This chapter discusses NOx formation, boiler NOx reduction, diesel fuel hazardous emission control and alternatives, and NOx control of internal combustion (IC) engines. Numerical calculations on gaseous fuel thermodynamic state, natural gas and coal combustions, and steam power are also presented.
