Coal peas should be stored in a dry, covered area to prevent moisture absorption. Moisture reduces combustion efficiency and can cause blockages in equipment. Use raised platforms or pallets to keep coal off the ground and avoid contamination. Proper ventilation helps prevent spontaneous combustion. Regularly inspect storage areas and cover stockpiles with tarpaulins when exposed to weather. This care ensures coal peas maintain quality and perform well when used.

Coal peas are generally suited for industrial and commercial heating systems rather than residential use. Their size and combustion properties may not be compatible with typical household stoves or fireplaces. Residential coal fuel usually requires smaller, specially graded sizes or briquettes designed for clean burning indoors. Using coal peas in residential systems can lead to inefficient burning, increased smoke, and equipment damage.

Coal peas are larger than coal duff, offering more stable combustion and less dust. Fines tend to burn quickly but create more smoke and ash, which can clog boilers and stoke systems. Peas provide a balance between size and energy output, making them preferred for mechanical stokers and industrial boilers. Handling peas is easier and safer, reducing health risks from coal dust inhalation common with fines.
