Types Of Coal Used In Chimney( ITTA BHATTA) | ईंट भट्टा में इस्तेमाल होने वाले कोयले की पुरी जानकरी

Summary

The video discusses the optimal coal mix for improving furnace efficiency, focusing on the quality of Indian and imported coal. It compares the calorific values of coal from different countries like the USA, Indonesia, Australia, and China, and recommends mixing ratios for power generation. It also explores the benefits of using high-grade coal from Assam, Jharkhand, and Raniganj, and suggests strategies for maximizing furnace performance.

Takeaways

• 🌟 The discussion is about coal quality and the best mixing ratios for coal to ensure good furnace quality.
• 🔍 There are two types of important coal: one from the USA and the other from Indonesia, with Australia and China also mentioned.
• 📊 The Gross Calorific Value (GCV) of coal is measured in kilojoules per kilogram (kJ/kg), and it's related to the coal's heat power.
• 📈 High GCV coal, such as 7000 kJ/kg, is desirable for its high heat power, and mixing ratios of 50% are suggested if needed.
• ⚠️ Avoid using coal that is too old as it can lead to increased fire risk due to higher heat power.
• 🌍 For Indonesian coal, the GCV is lower, making it a cheaper option, with values ranging from 6000 kJ/kg for low grade to 7000 kJ/kg for high grade.
• 🏭 Indian coal comes from various regions like Assam, Jharkhand, and Raniganj, each with different coal qualities and GCVs.
• 📝 Assam coal is considered good for its high GCV, ranging from 7000 to 7500 kJ/kg, making it suitable for chimney furnaces.
• 🏗️ Jharkhand coal is slightly more expensive but offers good quality with GCVs between 5500 and 6400 kJ/kg.
• 🚢 Raniganj coal has a GCV of 6250 to 6550 kJ/kg and can be mixed with other types for a balanced quality.
• 🔄 Mixing different types of coal can be beneficial, with suggestions to mix 50% Assam with other types for optimal results.
• 💰 The script also touches on the economic aspect of coal selection, highlighting the balance between quality and cost.
