Coal utilities are currently the major source of electricity in India. Share of coal fired power is usually in the range of 60%–65% (Ministry of Power 2020; Department of Industry 2020).Though the share of solar and wind power has increased over the last two decades, coal would continue to dominate the electricity sector in India in next few …
Introduction. Since the 1970s various technologies to control emissions of nitrogen oxides (NO x) have been used in countries with relevant emission standards.However, this is not the case in India, which has high-ash coals and until recently did not have NO x emission standards. NO x emissions control legislation has been …

Combustion is a chemical process in which a substance reacts rapidly with oxygen and releases heat as product. The original substance is called the fuel and the source of oxygen is called the oxidizer (Mathieu 2006).. Oxygen is required for any combustion process and ambient air is the most common source of oxygen that …

According to the U.S. Mine Safety and Health Administration, there were 104,895 fatalities from coal mining and other coal-related activities in the United States between 1900 and 2020.
In the burner area (burner A–E), the CO 2 content increases and reaches its highest mass fraction because in that area a combustion process occurs where CO 2 reacts with coal from the coal burner. This combustion reaction, if it occurs completely, will convert O 2 into CO 2 .
Introduction. Dilip Kumar, Deepak Kumar, in Sustainable Management of Coal Preparation, 2018. 1.5.2 Combustion. Coal combustion is an age-old practice for the generation of electricity but the quality requirements for various types of combustion systems are different. There has been considerable improvement in combustion technologies, of …
In the pulverized coal-natural gas co-firing combustion mode, the concentration of CO approaches zero at the end in the gaseous diffusion flames [56], while for coal flames, a small but finite amount of CO remains due to downstream char combustion in the heterogeneous combustion zone where CO is formed [57]. Once …
