🌟 Optimal Coal Mix for Quality and Cost

The first paragraph discusses the importance of selecting the right type of coal for various applications, focusing on the quality and cost-effectiveness. It highlights the significance of the calorific value (measured in GCV or Gross Calorific Value) of coal in determining its quality. The speaker mentions different types of coal imported from countries like America, Indonesia, Australia, and China, emphasizing the importance of prioritizing coal with a high GCV. The paragraph also delves into the specifics of Indonesian coal, explaining its lower cost due to its lower GCV and suggesting a mix of 50% Indonesian coal for optimal results. Additionally, the speaker advises against storing coal for too long to prevent issues like fire hazards due to high calorific value. The paragraph concludes with a discussion on Indian coal, specifically from Assam, Jharkhand, and Raniganj, and the different grades of coal available in the market.

Keywords

💡Coal

Coal is a black or brownish-black sedimentary rock primarily used as a fuel source in power plants and industrial processes. In the video's context, it is the main subject of discussion, with a focus on different types of coal and their quality in relation to their calorific value. For example, the script mentions 'America ka koyla' and 'Indonesia ka koyla' to compare different sources of coal.

💡Calorific Value (GCV - Gross Calorific Value)

The Gross Calorific Value (GCV) is a measure of the energy content of a fuel per unit of weight, typically expressed in kilojoules per kilogram (kJ/kg).
