A few facts are interesting: only 10% of electricity (20000 MW) is generated in coal-fired plants. Most of the other 90% is generated approximately equally by oil, natural gas, hydro and nuclear means. Most of the coal-fired plants are PF systems (an IGCC system, 58 200 t /day was dismantled in 1997).

The Acid Deposition Control Program is being implemented in two phases and has two major goals: reduction of total SO2 emissions by 10 million tons below 1980 levels by 2010, and reduction of NOx emissions from coal-fired boilers that will contribute to the overall target of a 2-million-ton reduction below 1980 levels by 2000.

2018-9-18 · NOx: New bituminous coal-fired boilers can be designed for NOx emissions from 150-250 mg/MJk,l if the boiler is equipped with low NOx burners; anthracite-fired boilers may produce emissions around 500 mg/MJf.i. Fig 3.4 below shows the uncontrolled NOx emission from coal combustion depending on firing technique and boiler size.

For example, in recent years the world crude oil price has ranged from about 15–35 $/barrel, or about 2–5 $/GJ.10 Coal is generally cheaper than oil, whereas natural gas is more expensive. The difference in price reflects the different costs of recovery, storage, and transport. and then only for boilers that operate at a high pressure
