Coal in small particle form (usually <10 mm). Due to its fine size, coal fines ignite easily and allow more even heat distribution.<\/p>\n
Coal with larger particle sizes (typically from 10 mm to 200 mm). This type remains in solid lumps with less breakage and dust.<\/p>\n
Coal imported from Indonesia, available in both fines and lump forms. It is well known for its cleanliness, stable calorific value, and competitive pricing.<\/p>\n

\u2705 Coal Fines \u2013 Advantages<\/h4>\n
\u2714\ufe0f Lower cost and operating expenses<\/strong>, suitable for standard systems.
\u2714\ufe0f Ideal for small to medium industrial boilers<\/strong>, cement production, agricultural drying, bricks, and tiles.<\/p>\n\u274c Coal Fines \u2013 Disadvantages<\/h4>\n
\u26a0\ufe0f Lower calorific value compared to lump coal of similar grade<\/strong>, meaning higher consumption to achieve the same heat output.<\/p>\n
\n\u2705 Lump Coal \u2013 Advantages<\/h4>\n
\u2714\ufe0f Lower ash content<\/strong>, cleaner operation \u2192 protects boiler tubes and reduces maintenance frequency.<\/p>\n\u274c Lump Coal \u2013 Disadvantages<\/h4>\n
\u26a0\ufe0f Higher price<\/strong>, reflecting higher processing costs and calorific value.<\/p>\n
\n\ud83d\udccc 4. Key Characteristics of Indonesian Coal<\/h3>\n
\ud83d\udccc Low sulfur content (<1%) \u2192 reduced SO\u2082 emissions
\ud83d\udccc Stable calorific value (around 3,800\u20136,800 kcal\/kg depending on grade)
\ud83d\udccc Competitive pricing compared to Australian coal or high-grade domestic coal<\/p>\n
