To answer the question of whether it is feasible to implement IIoT technologies in coal mines, one must understand the major components of IIoT systems and compare them with those that already exist in coal mines. By examining the IIoT technologies used in other industries, the following system core components are identified: (1) things, such as machines and people equipped with sensors ...
Coal and air pollution. When coal burns, the chemical bonds holding its carbon atoms in place are broken, releasing energy. However, other chemical reactions also occur, many of which carry toxic airborne pollutants and heavy metals into the environment.. This air pollution includes:

This must not be mixed up with the efficiency of power plants like nuclear, coalfired or natural gas turbine. These technologies are based on a thermodynamic cycle, which efficiency is in the order of 35%. This means that the combustion of coal, for example, will produce heat, which will be converted into mechanical energy and then into electricity. The global transformation is summarized on ...
