1A Run-of-mine (ROM) Lump Coal is a large-sized coal grade that is sorted based on calorific value and ash content directly from the mining output. As a high-heat fuel, it is specifically designed for industrial combustion systems requiring massive power and output.

Key Features:

Large grain size: Ensures a long-lasting and stable burn.
High calorific value: Ideal for high-temperature demands.
Heavy industry compatibility: Optimized for large-scale production.
Reasonable pricing: Cost-effective for bulk consumption.
