Solid fuel preparation – definition of briquetted coal Confirm the statement: “When finely ground coal is moulded under pressure with or without a binding material, the resulting fuel is called briquetted coal.”

Introduction / Context:Briquetting converts fine coal or coal dust into larger agglomerates for easier handling, transportation, and combustion. The definition focuses on forming under pressure, often with binders.

Given Data / Assumptions:

• Feed: finely ground coal or fines.
• Process: moulding or pressing under pressure.
• Binders: optional (e.g., molasses, pitch, bentonite) depending on coal rank and process.

Concept / Approach:Briquetted coal refers to densified, shaped products (briquettes) produced from fines. The essence is mechanical compaction (and sometimes thermal curing) with or without a binder to achieve strength and durability.

Step-by-Step Solution:Identify raw material: coal fines unsuitable for direct use.Apply compaction/moulding under pressure (with/without binder).Product obtained: briquetted coal — easier to store, transport, and burn.Hence, the statement matches the standard definition.

Verification / Alternative check:Industry practices (roller presses, piston presses) produce pillow or oval briquettes consistent with this definition.

Why Other Options Are Wrong:

• Restricting to specific coal ranks or additives is unnecessary; multiple feedstocks and binders can be used.

Common Pitfalls:Confusing “briquettes” with “coke” (destructive distillation) or “pellets” from ore fines; processes and products are different.

Final Answer:Yes
