Smoke wind and pulverized coal in thermal power plants

How do thermal power plants affect emissions?

Emissions from thermal power plants are influenced by many factors. CO2 and SO2 emissions are influenced by the chemical composition (particularly carbon and sulfur content) of coal and the coal usage per unit of electricity. NO emissions are influenced by the excess air used during combustion and the coal usage.

Are coal-fired power plants a source of air pollution?

The major attention has been paid to CO 2 emissions of the coal combustion but coal-fired power plants (CFPPs) may be also significant sources of other air pollutants such as SO x, NO x, particulate matter (PM) and trace pollutants (Córdoba et al., 2012a).

What are the emission control technologies for coal-fired power plants?

The particulate matter emission control technologies for coal-fired power plants have been developed since the 1960s, including cyclones (Wang 2020). The particulate size and composition generated during coal combustion depend on the coal quality, the boiler type, and capacity (Rallo et al. 2012).

Why is pulverized coal firing important?

Pulverized coal firing enabled the construction of larger boilers and power plants and became the predominant firing method for large steam-generating power plants beginning in the late 1920s [9, 10].

How do coal-fired power plants affect the environment?

Large amount of gaseous and particulate emissions from coal-fired power plants has different environmental impacts associated with them. High concentration of greenhouse gases (such as CO 2) is emitted from coal-fired power plants.

What is a coal fired power plant?

Note the two tall smoke stacks where the combustion products go into the atmosphere and the shorter, wider cooling towers. Coal fired power plants also known as coal fired power stations are facilities that burn coal to make steam in order to generate electricity. These stations, seen in Figure 1, provide ~40% of the world's electricity.
