Prospects of thermal power plants switching from ...

What we need is major changes in the energy industry towards environmentally effective use of coals and their processing wastes. In this research, we show the possibility of coal-fired thermal power plants and steam shops switching to coal-water slurries containing petrochemicals (CWSP). Extra calculations are made for fuel oil and natural gas.

COAL EXTRACTION AND PROCESSING

the process of subsurface coal extraction and thermal coal processing. Purpose Coal is used for its potential heat energy when burned and since the 1880s has been widely used to generate electricity in power plants. To to generate electricity coal is first burned inside a power plant and the heat generated by the coal is then used to heat water.
