    Coal is a solid particle. In thermal power plants the coal is ground to a fine powder and then burned. This is to ensure that each coal particle comes into to contact with air so that the chemical reaction can take place. If the furnace is only provided with the theoretical air there may be a possibility that some coal particles do not get sufficient air. If this happens that part of the coal Mar 01 2018 · 1. Introduction. In 2014 the share of electricity produced in the world from coal combustion was 40.8 .While this share will need to be drastically reduced in the coming decades to reach the current CO 2 emission targets it is nonetheless important to keep on increasing the efficiency of the existing assets worldwide in order to limit their global environmental impact.
