Fuel technology — briquetted coal production: “Briquetted coal is produced from finely ground coal by moulding under pressure, with or without a binding material.” State whether this industrial statement is correct.

Introduction / Context:
Briquetting improves the handling, combustion, and transportation characteristics of fine coal (slurry, fines, dust) by agglomerating particles into larger, stronger shapes. Understanding how briquettes are produced is useful for fuel preparation and emissions control topics.

Given Data / Assumptions:

• Finely divided coal feed (fines or slack).
• Application of pressure in moulds or roll presses.
• Presence of a binder is optional depending on coal rank and process.

Concept / Approach:
Briquetting uses mechanical compaction, sometimes with thermal assistance, to form dense solids. Binders such as molasses, pitch, tar, or starch may be added to improve green strength and durability. Some high-rank coals can briquette without binder under suitable pressure/temperature due to plasticity of inherent resins/tars.

Step-by-Step Solution:
Start with coal fines, screen and dry as needed.Optionally blend with binder and water to a target moisture/consistency.Compact in presses or moulds at high pressure; optionally cure/dry to develop strength.Use or store briquettes, benefiting from reduced dusting and improved combustion control.

Verification / Alternative check:
Industry practice includes pillow briquettes and roller-pressed ovoids produced exactly by this description, confirming correctness.

Why Other Options Are Wrong:
“False” would deny a standard, widely deployed coal preparation method.

Common Pitfalls:
Assuming a binder is always mandatory; many processes achieve binderless briquetting depending on coal properties and process temperature.

Final Answer:
True
