Innovative coal drying process benefits power plant

The system is designed with core safety principles: 1) Using low-temperature waste heat to slowly dry the coal without driving off volatiles; 2) processing the coal at just the right time before combustion to minimize the opportunity for moisture reabsorption and spontaneous combustion; and 3) using operating procedures and safety equipment to actively monitor and control the dryer conditions to respond …

DryFining Great River Energy

Reducing the amount of water in the coal through a drying process offers a number of benefits: Increases energy density and value of the lignite Reduces total volume of flue gases that must be handled throughout the system Improves overall power plant efficiency

Drying Technology an overview ScienceDirect Topics

The drying technology uses unused energy such as combustion flue gases or steam from on-site power plants to dry coal. The stabilization technology prevents spontaneous combustion from occurring in the process of stockpiling or transporting of coal after drying it.

Processinglow gradecoalto produce high grade products

Dry processing of coal requires no water and dry processing techniques are therefore very attractive considering our climatic conditions. Two dry processing technologies have been evaluated and implemented in South Africa, namely the FGX dry coal separator and X-ray sorting.

Coal Dryers Carrier VibratingEquipment, Inc.

Carrier vibrating fluid bed thermal dryers are typically used for coals with a larger size fraction, such as run-of-mine coal. Our vibrating fluid bed units are available in sizes up to 8 ft. wide x 50 ft. long with capacities up to 250 TPH in a single unit, depending on the thermal load. Carrier coal dryers utilize vibration which significantly assists in the fluidization of sticky and wet coals, and helps convey larger …
